General description
毛细管GC柱也称为开口管柱。载气流过中心孔，并且在整个柱长上不受限制。
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：
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
- 60 °C至200 °C (等温)或220 °C（程序性的）
Application
Nukol毛细管气相色谱柱可用于乳制品中C2-C8 游离羧酸的气相色谱分析。也可用于通过平衡透析，固相微萃取（SPME）和毛细管气相色谱法测定人血浆中丙戊酸的游离浓度。
The Nukol column is used for the analysis ofvolatile short-chain fatty acids (SCFAs). The Nukol column is specificallydesigned for volatile acids, allowing for the effective separation andquantification of these compounds in fecal samples. The GC system with theNukol column facilitates the measurement of SCFA concentrations, which are important metabolic products of gut microbial fermentation.
