Which chromatography methods pair well with mass spectrometery instrumentation?

Homework Answers

Answer #1

Gas chromatography-mass chromatography (GC-MS) method pair is suited with mass spectrometry instrumentation.

GC-MS is an analytical method to identify different substances within a test.

GC separates the chemical mixture into of pure chemicals. MS identifies and quantifies the chemicals.

GC-MS is used

1) To detect substances in luggage or human beings.

2) criminal forensics

3)Food ,beverage &perfume analysis

4) Environmental monitoring& cleanup

5) law enforcement
