✦ Synopsis

The research described herein concerns the use of the headspace technique coupled with gas chromatography for the quantitative determination of water in solid chemical compounds and pharmaceutical products. Samples were dissolved in alcohol and the water reacted with calcium carbide. The generated acetylene was measured with a flame ionization detector and related to the original amount of water in the sample. Samples were also analyzed by the Karl Fischer titration technique and the two sets of experimental data were subsequently compared.
