One of the chromatographic methods, systems in which the mobile phase is gas are called gas chromatography. Qualitative and quantitative analyzes of organic substances that can be made volatile without decomposing with temperature in gas chromatography are performed. The current system includes flame ionization (FID) and electron capture (ECD) detectors.
Application Fields
· FID is
sensitive to all compounds containing C-H bonds.
· ECD is often used in the analysis of chlorinated pesticides, as it provides significant improvements in the detection limits of highly electronegative halogenated organic compounds and aromatic pollutants.
