Chromosorb "Century Series" polymer supports are now available in 5 grades for more versatility than ever. Chromosorb 101 Fast, efficient separation of free fatty acids, glycols, alkanols, alkanes, esters, ketones, aldehydes and ethers.
Chromosorb 102 For light and permanent gas and low molecular weight compounds. No tailing of water and alcohols.
Chromosorb 103 Efficient, quick separation of amines, amides, alcohols, aldehydes and ketones.
Chromosorb 104 Highest polarity. Efficient separation of nitriles, nitro-paraffins, xylenols, and oxides of nitrogen and ammonia.
Chromosorb 105 Intermediate polarity. Separates aqueous mixtures containing formaldehyde and acetylene from lower hydrocarbons, water from organic compounds.

Industry Items An exclusive agreement for marketing a clinically oriented communicating computer system developed by Com Comp, Inc., Hauppauge, Ν. Υ., has been signed by Coulter Electronics, Inc., of Hialeah, Fla. Under the agree ment, Com Comp and Coulter will be working jointly on the development of additional products for computer man agement of medical and particulate data. Corning Data Systems, 3900 Elec tronics Dr., Raleigh, N. C. 27602, offers software programs that provide crystallographers with three-dimensional crystal structure plots. The software makes maximum use of the interactive graphics and built-in hard-copy fea tures of the Corning 904 terminal and is compatible with existing time-sharing crystal-structure analysis programs. The program is called TJnitcell. Indacom, Inc., 151 Route 10, Succasunna, N. J. 07876, 201-384-6105, is a newly formed company. Its first new product is a Polaroid X-ray align ment, jig designed specifically for use on the Polaroid XR-7 Land diffraction cassette for positioning and alignment of samples during X-ray transmission and back reflection Laue photography.
