Get the most consistent chromatography with more consistent Chromosorb® supports. Whether you're doing gas or liquid chromatography, the consistency of your results often depends on the consistency of your support material. For the most uniform results time after time, specify Chromosorb. Only Chromosorb diatomite supports are quality controlled from the ground up by one manufacturer. Only Chromosorb offers you three types of column packings to fit your needs.

The Chromosorb LC-Series Johns-Manville has a is the newest of the complete line of diatomite Chromosorb lines, supports for gas Currently two supports are chromatography too. available. LC-1 is the first Chromosorb A, G, Ρ and diatomite-based support W are specially processed compatible with all liquid diatomite supports phases. LC-2 is a available acid washed or pellicular packing non-acid washed for a specifically developed for variety of analyses. high-speed, highChromosorb G, Ρ and W efficiency liquid-solid can be ordered with a chromatography. LC-3, 4, DMCS treatment. 5 and 6 will be available in Chromosorb 750 and high the very near future. performance grades of W and G are highly efficient diatomite-based supports specifically designed for biomedical and pesticide analysis. A fluorocarbon resin, Chromosorb T, is used for separation of highly polar or reactive compounds.

The Chromosorb Century Series consists of eight porous polymer packing materials made of crosslinked resin with a uniform rigid structure of a distinct pore size and having different surface characteristics. They have found wide application in a number of difficult separations, i.e., water, gases, alcohols, fatty acids, glycols, etc. For technical assistance about any chromatographic situation, contact Jack Denboske, Johns-Manville, Box 5108-FM, Denver, CO 80217.
