EXHIBITION linear programmed temperature gas chromatograph, Model 500 linear pro grammed high temperature gas chromato graph, Model 40 linear temperature pro grammed gas chromatograph, Model 141 safety ignition unit—Schoniger oxygen flask, Hamilton microliter syringes, Halop o r t - F and other specialized column m a terials for gas chromatography, auto matic attenuator for gas chromatography, power supplies for thermistor and hot wire detectors.
TRITIUM-CARBON RADIO CHROMATOGRAPHS The chromatogram strip is scanned from both sides with two windowless flow counters (see insert). The chromatogram strip constitutes a part of the cathode of the detector, insuring highest sensitivity for tritium beta rays. Total background 3 0 counts/min. The scanning head can be decontaminated through immer sion in an ultra-sound bath or in boiling detergent. Gas consump tion: 1 No. 1A cylinder lasts for 4 0 0 0 hours.
Booth: I I I Forma Scientific, Inc. Box 649 Marietta, Ohio Exhibiting: Bacteriological hood, new electronic controls, a n d Dew-designed vacuum oven.
