Determination of formic acid content in industrial glacial acetic acid
Determination of formic acid content in glacial acetic acid for industrial use

Name: Packed column
Fixative: Sebacic acid
Carrier: GDX-103 (0.18-0.125mm)
Fixing fluid: carrier=7:100
Material: stainless steel/glass
Specification: 2m*3mm
Application: Agilent 7890, Shimadzu 2014
Application: Determination of formic acid content in industrial glacial acetic acid gas chromatography

Glacial acetic acid is one of the most important organic acids. Formic acid is the main impurity in glacial acetic acid, and its content directly affects the quality of glacial acetic acid. The current domestic and foreign standard method is to use chemical methods to determine trace amounts of formic acid in glacial acetic acid. The operation steps are cumbersome, time-consuming and laborious, and it takes about several working days to complete the measurement work, which cannot meet the needs of rapid measurement of trade settlement.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. proposed a gas chromatography analysis method to determine 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
