GC-MS

가스 크로마토그래피 질량 분석법(GC-MS)은 가스 크로마토그래피와 질량 분석법의 장점을 결합한 분석 방법입니다. 이 두 가지 기술을 결합하여 테스트 샘플 내에서 다른 물질을 식별해낼 수 있습니다. GC-MS가 사용되는 분야는 예를 들어 약물 검출, 공항 보안, 환경 분석 또는 알려지지 않은 샘플 식별 등 광범위합니다.

응용 분야 요구 사항

  • 가벼운 기체에 대한 우수한 펌프 속도

  • 높은 신뢰성

  • 낮은 전력 소비

How does it work?

A GC-MS is a combination between a gas chromatograph (GC) and a mass spectrometer (MS). The gas chromatograph is used to separate the sample which is carried through a capillary by an inert gas (typically Helium) and the mass spectrometer to identify the individual components. The output of the GC is then fed to the MS where the sample is ionized and put through a mass filter (typically a quadrupole or ion trap) and then analyzed. In some cases the sample can be further analyzed by using additional quadrupoles or TOF systems.

Product portfolio

All modern GC-MS systems are using a turbopump to reach the required vacuum levels. Pfeiffer Vacuum manufactures a broad range of pumps with the highest available reliability combined with excellent pumping speeds for light gases. To reach the essential pressure range, a backing pump is mandatory. The typical options for GC-MS systems are Rotary vane pumps, Scroll pumps or Diaphragm pumps. To measure your working pressure, Pfeiffer Vacuum offers a wide range of gauges. Several interfaces are available to ensure a proper connectivity between the different Pfeiffer Vacuum products using only one controller for all devices.
