名称:填充柱
固定液:癸二酸
担体:GDX-103(0.18-0.125mm)
固定液:担体=7:100
材质:不锈钢/玻璃
规格:2m*3mm
应用:安捷伦7890,岛津2014
应用:工业冰乙酸中甲酸含量的测定 气相色谱法

冰醋酸是最重要的有机酸之一,甲酸是冰醋酸中的主要杂质,其含量的多少直接影响冰醋酸的质量.现行国内外标准方法是利用化学方法对冰醋酸中微量的甲酸进行测定,其操作步骤繁琐,费时费力,完成测定工作约需要几个工作日,无法满足贸易结算的快速测定的需要.

浩瀚色谱(山东)应用技术开发有限公司提出了测定工业冰乙酸中甲酸含量的气相色谱分析方法。以癸二酸/GDX103为固定相,采用热导检测器,用乙酸乙酯作内标物的内标法定量,所测结果与化学分析法结果十分接近,最小检出量可达0.13μg,具有较满意的准确度和精密度

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
