Gas chromatography–mass spectrometry (GC-MS) is a powerful analytical technique used to separate and analyze volatile and semi-volatile compounds. It combines the separating power of gas chromatography (GC) with the detection and identification capabilities of mass spectrometry (MS).
The GCMS-QP2010 SE is a single quadrupole gas chromatograph-mass spectrometer offering stable and cost-effective analysis for challenging compounds. A high-performance quadrupole mass filter ensures high sensitivity in both quantitative and qualitative analysis. The GCSMS-QP2010 SE is compatible with multiple sample introduction methods to enable a greater range of applications.
Principle: Separates components of a mixture based on their distribution between a stationary phase (inside a column) and a mobile phase (an inert gas like helium or nitrogen).
Components: Includes a column (typically packed or capillary), a sample injector, an oven to control temperature, and a detector to monitor separated compounds.
Principle: Determines the mass-to-charge ratio (m/z) of ions produced from molecules after ionization, providing structural information and quantitative data.
Components: Involves an ion source (e.g., electron ionization, EI, or chemical ionization, CI), mass analyzers (e.g., quadrupole, time-of-flight, TOF, or ion trap), and detectors for ion detection.
Gas Chromatograph (GC): Separates analytes based on their volatility and interaction with the stationary phase.
Mass Spectrometer (MS): Detects and identifies separated analytes based on their mass-to-charge ratio and fragmentation pattern.
GC Phase: The sample is vaporized and injected into the GC column, where it undergoes separation based on its affinity for the stationary phase.
MS Phase: As compounds elute from the GC column, they are ionized in the MS ion source and fragmented. The resulting ions are separated based on their mass-to-charge ratio in the mass analyzer, and the detector records the abundance of each ion.
Environmental Analysis: Detection of pollutants in air, water, and soil samples.
Forensic Science: Identification of drugs, explosives, and trace evidence.
Food and Beverage Industry: Analysis of flavors, additives, and contaminants.
Pharmaceuticals: Drug testing, metabolite identification, and quality control.
High Sensitivity: Capable of detecting compounds at trace levels.
Selective Detection: Ability to distinguish between compounds with similar structures.
Quantitative Analysis: Provides quantitative data based on peak intensities.
