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.
For Liquid Chromatography (Circle 391)
For Gas Chromatography Diatomite Supports (Circle 392)
The Chromosorb LC-Series is the newest of the Chromosorb lines. Currently two supports are available. LC-1 is the first diatomite-based support compatible with all liquid phases. LC-2 is a pellicular packing specifically developed for high-speed, highefficiency liquid-solid chromatography. LC-3, 4, 5 and 6 will be available in the very near future.
Johns-Manville has a complete line of diatomite supports for gas chromatography too. Chromosorb A, G, P and W are specially processed diatomite supports available acid washed or non-acid washed for a variety of analyses. Chromosorb G, Ρ and W can be ordered with a DMCS treatment. Chromosorb 750 and high 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.
Porous Polymers (Circle 393) 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. Count on his support, count on our more consistent supports.
