Gas Chromatography System
GC-4000
Gas Chromatograph GC4000 is capable of detecting wide variety of compounds. GC4000 can be customized to meet your needs by choosing detectors and injectors. 3 kinds of detectors (FID, TDC, PDD*1) and 4 kinds of Injectors (Direct Injector, Split / Splitless Injector, Direct Injector with septum purge, Insert Injector) are available.
