Determination of formic acid content in industrial glacial acetic acid

Name: Packed column
Fixative: Sebacic acid
Carrier: GDX-103
Fixing fluid: carrier=7:100
Material: stainless steel/glass
Specification: 2m*3mm
Application: Agilent 7890
Application: Determination of formic acid content in industrial glacial acetic acid Gas chromatography


As an important organic acid, glacial acetic acid is mainly used in vinyl acetate, acetic anhydride, cellulose acetate, acetate and metal acetate. It is also used as a solvent and raw material for pesticides, pharmaceuticals and dyes in the manufacturing of photographic drugs. , Textile printing and dyeing and rubber industry have a wide range of uses.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. proposed a gas chromatography analysis method for determining the content of formic acid in industrial glacial acetic acid. Using sebacic acid/GDX103 as the stationary phase, using a thermal conductivity detector, using ethyl acetate as the internal standard for quantification, the measured results are very close to the results of chemical analysis, and the minimum detection amount can reach 0.13 μg. , With satisfactory accuracy and precision.
