Model 2 1 B Electrometer

INCREASE T H E SENSITIVITY OF YOUR GAS CHROMATOGRAPH The LOENCO Single or Dual Hy­drogen Flame Ionization Detectors, in conjunction with the Model 21 Β Electrometer, make a gas chroma­tographic quantitative analysis of organic compounds in parts per billion possible. This represents a sensitivity range several orders of magnitude beyond that of a ther­mal conductivity detector. Either of these detectors can be installed in the oven of your gas chromatograph or are available with the LOENCO Model 7 0 Dual Column Programmed Gas Chroma­tograph or the LOENCO Model 1 5B Series Gas Chromatograph. For complete information write for Data Sheet LOE-10.
