Information,
Microcalorimeter Model 351 RA microcalorimeter measures minute amounts of heating power, with a resolution of ±0.5 μνν. The calorimeter operates on the princi ple of voltage generation by heat con duction. Precise control of the environ ment around the calorimeter cells is provided by a water bath controlled to ±0.0002 °C in an air bath controlled to ±0.02 °C. The temperature range of the bath is 0 °C to 60 °C. Tronac, Inc. 421

Array Processor Digilab Hi-Comp 32 is a 32-bit array processor that enables users of the company's FTS-IR spectrometers to perform Fourier Transform calculations, including phase correction, apodization, and data transfer, in less than 1 s. The processor plugs into the computer used by the spectrometers. Applications range from real time GC/IR to high res olution gas phase spectroscopy. Price, $12 500 to $15 000, depending on the requirement for an expansion chassis. Bio-Rad Laboratories 422
Anion Exchange Columns SynChropak AX300 columns have a 10 μνη macroporous support with a poly merized amine coating. These HPLC columns can be used to analyze pro teins, isoenzymes, herbicides, nucleo tides and other anionic substances. The ion-exchange capacity of a 25 cm X 4.1 mm column is 25-50 mg for oval bumin. Elution protocols are similar to those on DEAE gels. SynChrom, Inc. 427
Concentrator Universal Automated Concentrator (UNACON) transfers undiluted solutes onto the GC capillary column after se quential traps remove the diluting sol vent (gas or liquid) from the samples. An integral flame ionization detector monitors sample processing, permitting the necessary control. The concentra tor accepts headspace or liquid injec tions, sparges aqueous samples, ther mally desorbs solids or sorbent tubes, and samples ambient air. It is available with or without an integral, tempera ture-programmed GC oven. Envirochem Inc. 435
