Follow the path that your carrier gas or detector fuel gases take to get to the GC. They start at either a gas tank or a gas generator, and travel through long lengths of tubing, pressure gauges, various fittings, and valves. Each is a potential culprit for introducing contaminants into your gas stream, which ultimately degrades chromatography results and shortens column life.
Typical contaminants, such as moisture, oxygen, and hydrocarbons wreak havoc with GC columns and detectors. Capillary and packed columns can degrade when exposed to moisture or oxygen, particularly at high temperatures. Detector performance may also be compromised. Since the detector can actually “see” the contaminants, spikes, baseline noise, and drift result.
Why Use Gas Purifiers?
A clean gas stream helps guarantee the quality of your GC analysis and the reliability of your results. It also helps prolong column life and minimize detector noise. Gas purifiers act as an insurance policy, protecting your instrumentation and analytical columns from these contaminants. They will not however, convert low purity gas into ultra high purity gas. Alltech carries a variety of gas purifiers in three different styles. See Table 1 for details.

Choosing the Right Gas Purifier for Your Application
There are a variety of gas purifiers available. Some remove a specific contaminant while others remove multiple contaminants from your gas stream. There are several factors you need to consider when selecting purifiers for your application. These include contaminants potentially present in your gas stream, gas purity levels required, flow and pressure limitations, space availability, and desired convenience when replacing spent traps.
Moisture, hydrocarbon, and oxygen traps are the most commonly used purifiers for GC applications. Moisture traps are typically packed with molecular sieves. After extensive heating, these crystalline structures lose their water of hydration opening a cavity that is readily filled with any compound that can fit. Water fits perfectly. However, it will also remove HCl, CO2, SO2, Cl2, or any gas with an effective diameter smaller than water.
Hydrocarbon traps are packed with an activated charcoal that adsorbs any organic compound larger than methane. Size and molecular weight of the organic contaminants will greatly effect the capacity of the trap, and to a smaller degree, trap efficiency. Activated charcoal has a higher capacity for larger (>C4) hydrocarbons than for smaller hydrocarbons.
Oxygen traps are packed with a metal catalyst. Oxygen is the most detrimental contaminant to analytical columns. It produces irreversible oxidation damage particularly to polar stationary phases. Refer to Table 2 for a recommendation of what purifiers to use for various GC applications.
Gas Purifiers and Traps
Table 1 - Gas Purifier StylesSTYLE BASEPLATE CARTRIDGE IN-LINE
You will also need to consider what physical characteristics your purifier should possess to meet your application requirements. Do you require 1/8" or 1/4" fittings, or are you performing bulk gas purification that requires 1/2" fittings? What are the pressure requirements of your application? This will determine if you need a purifier with a polycarbonate, glass, or metal body. Where will you be installing the purifier and is your installation space limited? This will determine the dimension and style of purifier you should choose.
Purifier Styles
Alltech offers three purifier styles – in-line, baseplate, and cartridge. The in-line style is the traditional style that is most commonly used. It can be directly installed into your gas lines with no support depending on its dimension or can be easily mounted on the wall with mounting clips. In-line purifiers must be removed from the gas line to be refilled or regenerated. We recommend installing them with quick-connect connectors and keeping an extra purifier on hand.
The baseplate and cartridge purifiers sit on the countertop making them easy to access when it is time to replace spent traps. Both styles can be installed in series with shut off valves allowing you to easily isolate them from your gas lines when it is time to replace them. Baseplate units allow you to easily refill the purifier with new adsorbent material. Cartridge purifiers allow you to quickly remove the spent purifier from your gas line and replace it with a new one.
Purifier Capacity
Purifier capacity indicates the amount of contaminant a trap is capable of removing before it reaches its point of saturation. It is dependent on both the adsorbent’s capabilities and purifier’s volume. You need to consider the amount of impurities in your gas stream and the volume of gas you need to purify. If you are purifying a large volume of gas or a less pure gas, you should select a high capacity trap with a large volume adsorbent bed that will trap and retain more contaminants.
Purifier Efficiency
Purifier efficiency is the most important purifier characteristic. It indicates how effective the adsorbent is at removing the desired contaminant from your gas stream. If your application requires high purity levels or the lowest detection limits, select a purifier that is packed with a highly efficient adsorbent material that removes contaminants to ppb levels.

Gas Purifier Installation Order
The order in which you install purifiers into your gas lines is very important. Figure 1 demonstrates the correct order for installing purifiers into your carrier gas line. The moisture trap should be placed first in line. Both hydrocarbon and oxygen traps will adsorb water. Installing a moisture trap before these traps prevents them from becoming prematurely saturated with moisture. It also allows them to more effectively remove their specified contaminants from the gas stream. The hydrocarbon trap should be placed after the moisture trap. A high capacity oxygen trap and an indicating oxygen trap should be placed closest to the GC. We recommend installing the series of purifiers as close to the GC as possible.
Gas purifiers should be installed in a vertical position to prevent channeling. Channeling is a phenomenon that occurs when a purifier is installed in a horizontal position. The adsorbent bed settles and the gas stream passes over the top of the bed rather than through the bed. The gas stream does not sufficiently interact with the adsorbent bed to effectively remove impurities.
Gas purification systems simplify purifier installation in to your gas lines. Systems are available as multi-adsorbent single purifiers or compact panels that contain multiple purifiers.
Purifier Replacement/Regeneration
You need to replace your gas purifiers before they are fully saturated. You can either change them at a predetermined time interval or use an indicating trap that changes color as it becomes saturated. There are potential problems with scheduled replacements. Undetected leaks or accidental exposure to air during cylinder changes can prematurely saturate gas purifiers. Early breakthrough means your column and detectors are exposed to a constant stream of damaging contaminants. An indicating trap located downstream from a high capacity trap is the best way to determine when it’s time to replace a spent trap. Some purifiers contain both the high capacity and indicating adsorbent in the same purifier body while others rely on a separate trap that serves solely as an indicator. Either way, purifier replacement should coincide with the first signs of color change in the indicating adsorbent.

PTFE FerrulesPTFE ferrules are completely inert and an economical
choice. They have an upper temperature limit of 250°C. PTFE ferrules conform well to the shape of the column upon compression and can be reused if handled carefully.
Graphite FerrulesThese 99.95% pure graphite ferrules can be used at
temperatures up to 450°C without producing bleed or decomposition products. The one-piece design requires no back ferrules. Graphite ferrules are very soft and conform well to the column on compression. These ferrules can be reused as long as care is taken not to overtighten them.
Vespel® FerrulesVespel® ferrules do not cold flow, are easily reusable,
and withstand temperature up to 350°C. At high temperatures, Vespel® may adhere to glass or metal.

Vespel®/Graphite FerrulesComposites of Vespel® and graphite combine the
advantages of the two materials. They are less likely to adhere to the column than Vespel® but are more durable than graphite. Ferrules are easy to reuse and stable at temperatures to 400°C.
Two types of composites are available. The VG1 composite is 85% Vespel®/15% graphite and suitable for all-purpose applications. The VG2 type is 60% Vespel®/40% graphite and exhibits added lubricity.

SWAGELOK® Tube FittingsSWAGELOK® Tube Fittings provide a leak-proof,
torque-free seal at all tubing connections and eliminate costly, hazardous leaks in instrumentation and process tubing.
All the action in the fitting moves along the tube axially instead of with a rotary motion. Since no torque is transmitted from the fitting to the tubing, there is no initial strain which might weaken the tubing.
CAUTION: Do not mix or interchange parts of tube fittings made by other manufacturers with SWAGELOK® tube fitting parts.

AT™ Steel - Activity Tested Steel TubingDelivers the Strength of Stainless Steel and the Inertness of Deactivated Fused Silica
• Flexible, and strong • Maximum temperature limit of 340°C to 350°C
A combination of chemical vapor deposition techniques and silicone chemistries transform durable stainless steel tubing into a chromatographically inert material. AT™ Steel activity tested steel tubing is suitable for sample loops, transfer lines, capillary and packed GC columns.
AT™-Steel may be cut with standard tubing cutters or high speed wheel cutters and can be rinsed with common solvents to remove particulates and contamination that have built up during use. To ensure a truly inert pathway, use AT™-Steel treated fittings. Sold separately below.
Choosing a Tubing MaterialA number of options are available for packed column tubing. The most inert material is glass, which should be used for active compounds. Glass-lined tubing and AT-steel™ provide the inert surface of glass combined with the mechanical strength of a metal column. Metal tubing provides an economical and rugged column for suitable application. Passivated nickel tubing can frequently be used with active compounds such as phenols and amines. Stainless steel tubing is recommended for hydrocarbon, fixed gas, and solvent analyses where column inertness is less of a concern. PTFE tubing is extremely inert, but due to temperature limitations and poor column efficiency, PTFE is generally only recommended for the analysis of corrosive gases which are too reactive for glass.
HI-EFF® Stainless Steel tubing meets the exact specification required to fabricate GC columns. Tubing is specially tempered for easy bending. Type 304 is the most commonly used for GC. Type 316 offers more corrosion resistance.

With so many septa to choose from, choosing a septum for your application can be a confusing task. There are a number of criteria you need to consider when selecting a septum.
1. Make and Model of Gas Chromatograph – This will determine what size of septum you need. Alltech carries a full range of septum sizes to fit most gas chromatographs.
2. Performance – A high performance, low bleed septum is desirable so that septa bleed does not interfere with the chromatography of your sample. Keep in mind that all septa bleed to some extent. The amount of bleed visible to the detector is affected by several factors which include:
- The composition and pretreatment of the septum material.
- The sensitivity setting of the detector amplifier.
- The type of detector. - The injection port setting. - Isothermal or temperature programming. - The type of injection (direct, splitless,
split, etc.)
Choose a high performance septum such as Alltech’s ThermoRed or XLB septa to minimize septa bleed.
3. Injection Port Temperature - The temperature of the septum never reaches the injection port temperature setting. The center of the injector heated zone, where the sample is deposited, is regulated to correspond to the injector port setting. Be sure to select a septum with a maximum temperature that exceeds your injection port temperature.
4. Penetration/Resealing Qualities - Ideally, you want a septum that is soft and easily penetrated by a syringe needle and has excellent resealing properties. This will prevent you from bending syringe needles and coring of the septum to give you longer septum life. Excellent resealing properties will prevent leaks that might adversely affect your chromatography or damage your analytical column.

The JADE™ Mechanical Inlet works like a miniature airlock. First, the syringe needle passes through a needle guide forming an annular seal. Next, the needle guide encounters the ball-and-seat valve, unseats the ball, and enters the injection port. When the needle is removed from the ball valve, a powerful return magnet pulls the ball back onto the seat, sealing the injection port.
The elegantly simple ball-and-seat is the system’s most technologically complex component. For the utmost in reliability, it uses sophisticated materials and close tolerances found in the most advanced instrumentation.
The JADE™ Inlet’s long lifetime, heat resistance, and low-maintenance design make it the obvious solution for autosampling. After the JADE™ Inlet is installed, there’s minimal need for operator attention, enabling chromatographers to focus on more important tasks instead of monitoring septum failure.
Ultimately, the JADE™ Inlet serves as a vital link in implementing online GC applications where system longevity, reliability, and low maintenance are absolute requirements.

Installing a JADE™ Inlet*
After removal of the septum nut and septum, clean out old septum particles. A polyimide gasket (included) is placed in the septum well.
A one-time bake-out step is recommended to remove residual septum materials from the injection port. The brass bake-out plug (included) is installed on the adapter nut for this step. The bake-out plug is removed when done.
The adapter nut is threaded on to the injection port finger tight.
The JADE™ Inlet body is threaded into the adapter nut finger tight. With the appropriate wrench in place on the adapter nut, tighten the valve body 1/4 to 1/2 turn using a 1/2" wrench. The completely assembled JADE™ Inlet is now ready for worry-free operation.

The Valco® 2-position helical actuators permit the application of controlled, constant torque for the actuation of rotary devices. Minimum actuation pressure is typically less than 30psig for operation of Valco® sample injection and switching valves. Low internal leakage permits either pulsed or continuous operation with low gas consumption.
Actuators are designed for room temperature operation, but high temperature versions are also available. Valves intended for mounting in ovens or heated detector zones are used with a stand-off assembly which locates the actuator out of the heated zone and supports both valve and actuator.
