Ultra-Sensitive, Completely Safe, Ionizing Detector Analyzes Fixed Gases and Both Organic and Inorganic Compounds Column Temperature Programming—Either Manual or Automatic
The new Burrell Kromo-Tog Model K-7 is designed for the most accurate chromatographic analysis possible. Its thermionic emission ionization detector has greatly increased sensitivity, speeds analysis and permits use of small diameter columns and smaller samples. It is the only method that will analyze both organic and inorganic compounds as well as fixed or permanent gases. Superior standard equipment includes a gas sampler, column temperature indicator, automatic controller for constant or programmed temperature operation, built-in flowmeter, and flash vaporizer. Potentiometer recorder, offered separately, mounts next to Model K-7 on laboratory bench or table top. McLeod gage has adjustable closed end that enables reading three ranges on a single scale. The linear scale is 100 mm. long, and the three ranges are 0 to 1.0 mm. in 0.01-mm. divisions, 0 to 0.1 mm. in 0.001-mm. divisions, and 0 to 0.01 mm. in 0.0001-mm. divisions.
