Gas Chromatography (GC) is a universal separation technique applicable to complex mixtures. The technique uses differences in volatility and analyte-column interaction to achieve the desired separation. GC is commonly used to analyze mixtures for identification and quantification. Assay and trace level analyses are achieved with minimal sample preparation.
A wide variety of special detectors is available for quantification and specific identification of various classes of compounds. Various ancillary GC techniques, such as headspace/GC-MS, pyrolysis/GC-MS, and other multidisciplinary techniques, are available to solve client problems.
GC techniques are cost effective and encompass a wide range of analytical problems. GC can be used for:
- Quantification by direct injection or headspace/gas chromatography to determine composition of solvent blends and additives in manufactured products
- Identification and quantification of residual monomers and solvents in product formulations
- On-line monitoring of reactions or emissions for kinetic studies, emission testing, and specific environmental surveys
- Trace-level analysis of analytes for industrial hygiene surveys, product contamination, environmental studies, and waste analysis
- Pyrolysis/GC and pyrolysis/GC-MS for identification of thermal decomposition products of polymeric materials
