What is Gas Chromatography Mass Spectroscopy (GCMS)?
Gas Chromatography-Mass Spectroscopy (GCMS) combines powerful separation technology with precision mass detection to identify unknown compounds, quantify specific substances, and analyze complex mixtures with exceptional accuracy.
Our Process
Sample Introduction
The sample is injected, vaporized, and carried by an inert gas.
Separation
The vaporized sample moves through a column, separating compounds by boiling points and interactions.
Ionization & Detection
Compounds exiting the column are ionized, forming charged fragments that are detected and recorded.
Data Analysis
The resulting mass spectrum identifies the compounds and quantifies their concentrations.
