Abstract: In the pharmaceutical industry, gas chromatography (GC) is routinely used for analyzing volatile and semivolatile compounds. While GC is frequently employed for quantitative reporting of residual solvents in raw materials and finished products, this technique is also now gaining popularity for the impurity testing of process gases, such as nitrogen. Molecular sieve PLOT capillary GC columns are the column of choice for analyzing these gases, due to their ability to separate light components. In this article, the authors provide an overview of process gas testing and example chromatography specifically for the pharmaceutical industry.
