Modern gas chromatography with MicroTek detectors-
sensitivity plus specificity ELECTRON CAPTURE FOR HALIDES The ultimate in sensitivity. High temperature units using Ni63 (Micro-Tek patent pending) have already revolutionized many analyses involving chlorides. FLAME PHOTOMETRIC FOR PHOSPHORUS AND SULFUR This exclusive system (Melpar patent pending) has made nanogram sensitivity routine, even in several thousand times excesses of other compounds. ELECTROLYTIC CONDUCTIVITY FOR HALIDES AND NITROGEN The unique Coulson unit (U.S. patent 3309845) now extends similar performance to halides and nitrogen-containing compounds. It offers completely new possibilities in the analyses of many pesticides, alkaloids and amino acids.
MT 220 Gas Chromatograph with four-column four-inlet system and electron capture, flame photometric and Coulson detectors plus new total solid-state dual-channel electrometer and temperature programmer.
COMBINATION SHOWN FOR THE FIRST TIME AT CLEVELAND
Sensitivity used to be the only major requirement for a good gas chromatograph.Now, thanks to a new generation of specific detectors, you can pick out many trace components without interference even from large excesses of other materials. The MicroTek detector combinations can bring literally a new dimension into your analytical work.
