The CRAC research centre applies state-of-the-art GC and GC-MS techniques for analysis of gas, liquid and solid samples of organic compounds. A Varian GC-MS system (CP-3800 GC coupled to Varian 2000 MS),  is used for qualitative and quantitative analyses of hydro­carbon mixtures including carbonyls, aromatics, PAHs etc. The MS has a mass range up to 650 m/z and is also equipped with a chemical ionisation unit. An automatic injector for gas samples is also available.
