Introducing an entirely new GLG column packing for fast, efficient separation
Chromosorb* 101 Chromosorb 101 is a porous polymer resin developed and synthesized by .Johns-Manville for use as column packing in gas-liquid chromatography. It is especially effective in the rapid, efficient separation of free fatty acids, glycols and alcohols, and also separates esters, ketones, aldehydes, ethers, and both aliphatic and aromatic hydrocarbons. Chromosorb 101 is thermally stable at temperatures in excess of 325°C. Consequently, its applicability extends to high molecular weight (C22) compounds. For more specific information, write for our bulletin FF-177. Johns-Manville, Box 1960, Trenton, N. J.
Johns-Manville *Chromosorb is a Johns-Manville registered trademark for its brand of products developed for use as support material or adsorbents for gas chromatography.
You get better water for less cost— Two cartridges in Series give you more than twice as much pure water as two single cartridges separately. You get 15-megohm purity and you can use (the color change tells you) the left one to complete exhaustion, before replacing it with the right hand one. A new Cartridge on the right side brings you back to full potential again. Write for a copy of NEW Bui DX-268 for a complete description of operation, capacity, and costs.
