GCMS (Gas Chromatograph and Mass Spectrometry)
What is Gas Chromatograph and Mass Spectrometry (GCMS)?
GCMS (Gas Chromatography and Mass Spectrometry) is an integrated device of GC and MS, a precise analytical instrument for detecting what (qualitative) and how many (quantitative) compounds are. GC separates the vaporized samples into the chromatographic column, and the separated compounds enter the MS for detection. It can be widely used in environmental protection, food safety, electronics industry, flavor and fragrance industry, textile industry, petrochemical industry, pharmaceutical industry, judicial appraisal, and other fields.
Features of Gas Chromatograph and Mass Spectrometry
- Independent research and development of GC system with electronic flow and pressure control (EFC, EPC);
- Independent research and development and efficient filament, electron emission efficiency is high, the largest up to 350 mu;
- Single quadrupole mass with pre quadrupole analyzer effectively reduces the sample measurement process of quadrupole pollution;
- High energy conversion with an electron multiplier provides excellent sensitivity;
- Import of mechanical pump and molecular pump excellent vacuum system, ensure the high stability and reliability of the system;
- Equipped with a full range of vacuum gauges, real-time monitoring vacuum conditions;
- A perfect protection system to ensure that the instrument is an abnormal condition of the protection system of key parts, prolong the service life of the instrument;
- The advanced RF power digital compensation technology can make all the quality within the scope of the mass spectrum peak to achieve high sensitivity and resolution.
Application Areas of GCMS
GCMS is widely used in the environmental protection industry, electronics industry, textile industry, petrochemical industry, flavor and fragrance industry, pharmaceutical industry, agriculture and food safety, and other fields;
- Industrial fields: textile electronics, plastics, cosmetics.
- Food safety: pesticide residues, flavors and fragrances, additives, packaging materials.
- Environmental protection: atmosphere, water quality, soil, solid waste.
- Bio-pharmacy: pharmaceutical factories, drug testing.
- Petrochemical industry: oil refineries, chemical plants.
- Public prosecution and law system: criminal investigation, analysis of hazardous materials, identification of physical evidence.
