Application of GC1290 Gas Chromatography:

GC1290 gas chromatography is a chromatographic analysis method with gas as the mobile phase, which is mainly used for the separation and analysis of volatile substances. Gas chromatography has become one of the most important separations and analysis methods, and has been widely used in the fields of medicine and health, petrochemical industry, environmental monitoring, biochemistry, and so on.

Features of the Gas Chromatography:

1. Control system: designed for monitoring and controlling the instrument via the computer.
2. Column Compartment/oven with superior thermal performance, multistage (10 ramps) programmed temperature control function. (supported by “control system”).
3. Advanced built-in data acquisition system, supporting real-time instrument status monitoring, detection signal acquisition, and PC control.
4. Column oven accommodates up to 3 chromatographic columns, and supports quick heat-up and rapid cool-down with the automated back-door opening. (400℃ to 50℃ in 6 min at 25℃ ambient).
5. Flexible sample introduction system: 3 sample injectors could be installed and operated simultaneously with independent temperature control.
6. High sensibility and stability detector.
7. 2 independent and analog signals output.
8. Clarity software, compatible with GLP/FDA-21 CFR Part11 requirements and regulations. (electronic records and signatures).
9. Special analyzers, like RGA, NGA, PINDA, etc. according to ASTM standards.

Gas chromatography and accessories:

1. Carrier Gas System + Sample Introduction System + Separation System + Temperature Control System + Detector
2. Carrier Gas System: air source/ purification and desiccation device/ flow rate control device
3. Sample Introduction System: sample injector
4. Separation System: chromatographic column(packed column and capillary column)
5. Temperature Control System (Column Oven): constant temperature and programmed temperature
6. Detector: FID/ FPD/ NPD
