"Gas Chromatography/Mass Spectrometry (GC/MS)" explains how GC-MS works and its applications.
What is GC-MS?
GC-MS is an analytical method that combines gas chromatography and mass spectrometry to identify compounds in a sample
It can be used to detect unknown compounds, identify safety hazards, and perform qualitative and quantitative analysis
How does GC-MS work?
The gas chromatograph separates the molecules in a sample by passing it through a capillary column
The mass spectrometer then analyzes the separated molecules by breaking them into ionized fragments and detecting their mass-to-charge ratio
What are some applications of GC-MS?
Drug detection
Environmental analysis
Explosives investigation
Food safety
Water contamination analysis
Petroleum product analysis
Forensic urine drug testing
