描述

一般說明

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.

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）

應用

Nukol Capillary GC Column may be used in the quantitative determination of C₂-C₈ free carboxylic acids in dairy products by gas chromatography. 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.
