Answer Posted / Alok Kumar Pandey
Dichlorobenzene, nitrobezine, and t-butyldi sulfate are often used as internal standards in Gas Chromatography (GC) headspace analysis. They serve as references to ensure accurate quantification of the analytes of interest. Dichlorobenzene and nitrobezine have different retention times than most common volatile organic compounds (VOCs), making them suitable for calibration. t-Butyldi sulfate is a silylating agent that enhances the response of VOCs, improving sensitivity.
