GC1120 Gas Chromatography

GC1120 Gas Chromatography is a kind of instrument for qualitative and quantitative analysis of multicomponent complex mixture by using chromatographic separation technology and detection technology. Generally, it can be used to analyze the thermal stable organic compounds in soil, such as volatile organic compounds, organic chlorine, organic phosphorus, polycyclic aromatic hydrocarbons, phthalates, etc.

Application of GC1120 Gas Chromatography

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 GC1120 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.
  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. M6 software, compatible with GLP/FDA-21 CFR Part11 requirements and regulations. (electronic records and signatures).
