The biggest challenge with XRF…

• XRF analysis is only as good as the standards used to set up the calibrations

– International standards

– Vendor-supplied standards

– In-house standards

– Custom standards

– “Standardless”


PANalytical Solutions for the Middle East

• OIL TRACE & VHG Calibration Sets– For the oil & fuels industry

• ADPOL & TOXEL– For the polymers & plastics industry

• WROXI– For the mining & cement industries and academia

• CEMOXI– For the cement industry

• OMNIAN– Standardless analysis for everyone

• Customized solutions for our customers3Middle East Workshops April 2012

PANalytical Solutions: Oil & Fuels Industry

• OIL TRACE– Is a package that contains mathematical

corrections for the analysis of oils and fuels

– S in petroleum products

– Fe, Na, Sb & K for process efficiency

– Additives & stabilizers in lubricating oils

– Wear metals in lubricants

– S, Ni, Cl and V in waste oil

– Petroleum coke analysis



• Automatic dark matrix (COH) corrections– ensures that all types of petrochemical liquids can

be analyzed with the same package



• Independent of sample volume, density & mass

– Wedge effect (fluorescence volume geometry –FVG) correction




Calibration



Sample Analysis


• VHG Laboratory Standards– Individual calibration sets

• S in diesel

• S in white oil

• S in isooctane (gasoline)

• S in biodiesel

• S in crude oil

• Pb in gasoline

• Wear metals in oils and fuels

• Additives in lubricating oils9Middle East Workshops April 2012

Example: Sulfur in Petroleum Products

• Sulfur in diesel according to ISO 20884:04 & sulfur in oil according to ASTM D2622-10


Oil Trace - Sulfur in Petroleum Products


• Precision of the results (norm conformity)

Oil Trace - Sulfur in Petroleum Products


Oil Trace – Additives in Lubricating Oils

• Analysis of additives in lubricating oils according to ASTM D4927 & D6443


PANalytical Solutions: Polymers and Plastics

• ADPOL – Developed by PANalytical & DSM-Resolve

Polymer R&D Laboratory

– Specifically for the analysis of F, Na, Mg, Al, Si, P, S, Ca, Ti, & Zn as additives in plastics and polymers



• ADPOL Package Contains– 4 polyethylene based CRM’s (40 mm x 2 mm)

– 1 blank

– All as pressed disks (ready for use)

– Duplicates of the CRM’s

– Certificates

– CD for setup


Example: Analysis of sub-ppm Ti in polyolephins


• Ti is a constituent of the relatively expensive Ziegler-Natta catalyst system, used in the production of polyolephins

• Determining [Ti] is important for quality control and catalyst recovery

Example: Analysis of sub-ppm Ti in polyolephins



• TOXEL– Similar to ADPOL

– For the analysis of toxic metals, including Cr, Ni, Cu, Zn, As, Br, Cd, Ba, Hg & Pb in polyethylene


PANalytical Solutions: Minerals

• WROXI– Wide Range Oxides

– Minerals analysis module for mining,

cement and other applications where the

analysis of oxides is important




1. Fuse the standards

2. Setup calibrations

3. Fuse your unknown samples

4. Analyze the unknowns against calibrations



WROXI



• Accuracy of WROXI



• Accuracy of WROXI continued…


• Accuracy of WROXI continued


PANalytical Solutions: Cement

• CEMOXI– Cement Oxides

– Cement analysis module,

specifically for the cement industry

(adapted from WROXI)

– Covers the analysis of raw materials,

raw mix, clinker & cement


PANalytical Solutions: Cement


PANalytical Solutions: “Standardless”

• OMNIAN– Analysis of all sample types without dedicated

calibrations

– Large elemental range

– Market-leading accuracy





• 2 Steps in the “Standardless” Approach1. Identify the elements (not required for

conventional approach)

• Advanced algorithms for the determination of background, peak search & match and line overlaps

2. Quantify the elements

• Scan-based measurement for the full elemental composition (default / fast scan)

• Combined with peak measurements for higher precision and lower detection limits



• Elemental ID & quantification for all sample types– Calibrations set up with a selected range of reference

materials to calibrate instrument response

– Elemental range: O to U

– Adaptive Sample Characterization (ASC) corrects for sample matrix variations and automatically selects the correct calibration for the sample

– Finite Thickness (FT) correction for thin/low density samples

– Fluorescence Volume Geometry (FVG) corrections for liquids and low density samples

– Dark Matrix corrections

– Most sample types, including solids, pressed powders, fused beads, loose powders & liquids


“Standardless” Examples


NIST 1831 Glass Standard

Low alloy steel standard (BAS SS 405)



Poplar leaf standard GSV3



etc…….
