Agilent 7820A GC System can be used to simply determine formic acid in acetic acid
This document presents an analytical method for determining formic acid in acetic acid using the Agilent 7820A Gas Chromatograph. The method utilizes a micro thermal conductivity detector (pTCD) and an Agilent J&W DB-FFAP capillary column to achieve better separation and repeatability compared to previous packed column methods.
