GCMS (Gas Chromatograph and Mass Spectrometry)


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
  • 1. Independent research and development of GC system with electronic flow and pressure control (EFC, EPC);
  • 2. Independent research and development and efficient filament, electron emission efficiency is high, the largest up to 350 mu;
  • 3. Single quadrupole mass with pre quadrupole analyzer, effectively reduce the sample measurement process of quadrupole pollution;
  • 4. With high energy conversion with electron multiplier provides excellent sensitivity;
  • 5. Import of mechanical pump and molecular pump excellent vacuum system, ensure the high stability and reliability of the system;
  • 6. Equipped with a full range of vacuum gauge, real-time monitoring vacuum conditions;
  • 7. Perfect protection system to ensure that the instrument is abnormal condition of protection system of key parts, prolong the service life of the instrument;
  • 8. 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;
