The first separation of acids by gas chromatography (GC) coincides with the inception of GC itself. In 1952 James and Martin pioneered GC by demonstrating the separation of the C1 to C12 aliphatic acids on a stationary phase of silicone oil DC 550 containing stearic acid or H3PO4 and quantifying using a special titrimetric detector. Since then, the GC analysis of acids has been extended to a very wide variety of species and samples. To enable ready application of GC, the acids are usually converted to suitable volatile derivatives for resolution on efficient columns. As they are eluted they must be identified by an appropriate technique, the most definitive being mass spectrometry (MS). Various applications are presented in this article.
