TSINGTAO UNICOM-OPTICS GC9790Series Gas Chromatographs are new generation products. Instruments adopt the most advanced microcomputer control system and large LCD with both Chinese and English display. Carry out all control and analysis on PC. Built-in A/D converter is available for option, Chromatography signal output digitally. High liable and high sensible micro current amplifier heightens the FID detection limit. New model TCD detection sensibility heightens 5 times than common TCD.
