Advanced Gas Chromatography

Application of Gas Chromatography

  1. Drugs and Pharmaceuticals – GC is used not only in the quality control of this field but also in the analysis of new products and the monitoring of metabolites in biological systems.
  2. Environmental Studies – GC is often used for air pollution analyses. Many chronic respiratory diseases (asthma, lung cancer, emphysema, and bronchitis) could be results of air pollution. Air samples can be very complex mixtures, and GC is unique adaptable to the separation and analysis of such mixtures.
  3. Petroleum Industry – The petroleum companies were among the first to make widespread use of GC. The technique was successfully used to separate and determine the components of various petroleum products.
  4. Clinical Chemistry – Gas chromatography is adaptable to such samples as blood, urine, and other biological fluids. Compounds such as proteins, carbohydrates, amino acids, fatty acids, steroids, triglycerides, vitamins, and barbiturates are handled by this technique directly or after preperation of appropriate volatile derivatives.
  5. Pesticides and their Residues – GC in combination with selective detectors such as electron capture, phosphorus, and electrolytic conductivity selectors have made the detection of pesticides and their measurement relatively easy.
  6. Foods – The determination of antioxidants and preservatives in food is an extremely active part of the GC field. Adaptations and sample types are almost limitless.
