Accucore - Core Enhanced TechnologyTM

Solid Core Particles – 2.6µm diameter particles with a solid core generate high speed, high resolution separations without excessive backpressure

Advanced Bonding Technology – Optimised phase bonding creates a series of high coverage, robust phases

Tight Control of Particle Diameter – Enhanced selection process keeps particle size distribution to a minimum and produces high efficiency columns

Automated Packing Process - Enhanced automated procedures ensure that all columns are packed with the highest quality

Kinetic Plots

• Allows for fairer comparisons of analytical systems • Van Deemter just compares pure separation ability

• Incorporates time of analysis

• Analysts want FASTER chromatography • Van Deemter plots do not specify the time of analysis

• Incorporates pressure limitations of systems

• Van Deemter does not account for a pressure limitation on system

Impedance

• Devised by Knox and Bristow in 1977 • Defines the resistance a compound has to moving

down a column relative to the performance of that column

• Allows for pressure to be incorporated

• Often plotted with a reverse axis • Mimics van Deemter plot • Minimum value optimum conditions

• Often plotted as a dimensional form
