Title: Chapter 3 Gas chromatography (GC): Principles and applications
Abstract: This chapter focuses on gas chromatography (GC), which is widely used in foods, petroleum products, pesticide and pesticide residues, pharmaceutical products, environmental monitoring, and clinical chemistry. The major advantages of modern GC reside in the high resolution, the speed, the sensitivity, the precision, and the accuracy that characterizes it. A GC system is composed of four major components: carrier gas source, sample introduction system, column, and detector. GC has become a well-established and powerful analytical technique, but there are some limitations to it. It requires an auxiliary spectroscopic system to confirm the identity of peaks. Another major limitation is that GC is applicable only to thermally-stable volatile compounds. The flame ionization detector (FID) is the most popular detector for GC. It utilizes a flame produced by the combustion of hydrogen and air. For optimal FID operation, the carrier, hydrogen, and air flow must be properly set and adjusted.
