说明

一般描述

应用：将酸官能团引入相中使该色谱柱具有酸性，可用于分析挥发性酸性化合物。可以对难分析的羧酸（游离脂肪酸）以优异的峰形和最小的吸附量进行分析。
USP编码：该色谱柱满足USP G25及G35要求。
相：

• 键合的
• 酸改性的聚乙二醇

温度限制：

• 60 °C至200 °C (等温)或220 °C（程序性的）

应用

Nukol capillary GC column may be used for quantitative determination of free volatile fatty acids (FVFA) from dairy products.[1] It may also be used for the determination of the free concentration of valproic acid in human plasma by equilibrium dialysis followed by solid-phase microextraction (SPME) and capillary gas chromatography.[2]
