FiD Gas chromatograph Introduction
The GC112N FID gas chromatograph is a microcomputer based, high-performance, low-priced, and newly designed universal gas chromatograph. It has the advantages of high stability and reliability, simple and reasonable structure, convenient operation, and beautiful appearance. This instrument has a wide range of applications and is suitable for trace detection of pollution in environmental protection, atmosphere, water sources, etc; Analysis, monitoring, and research of toxins; biochemistry; Clinical application; Pathological and viral research; Food fermentation: petrochemical industry; Petroleum processing; Oil analysis; Geological and mineral exploration research; Organic chemistry; Synthesis research; health quarantine; Analysis and research on public hazard detection. The main components of GC112N gas chromatograph
GC112 FID gas chromatograph is equiped with a FID detector.FID is the abbreviation of Flame flame ionization detector which is a high sensitivity universal detector.
It has response to almost all organic substances, but has no response or very little response to inorganic compound substances, inert gases or undivided substances in the flame.
FID gas chromatograph need use pure hydrogen as flame gas.pure nitrogen as carrier gas.you can consider onsite hydrogen generator and nitrogen generator to replace dangerous gas cylinder.
