Nickel tubing may be substituted for glass in the fabrication of gas chromatographic columns for use with samples of biological interest. Comparisons of separations of mixtures of steroids, narcotic alkaloids, phenothiazines, and amphetamines on stainless stell, glass, and nickel packed columns showed little or no observable sample decomposition on glass or nickel as contrasted to complete loss of certain compounds on stainless steel. The nickel columns are easily prepared, durable, economical, and not subject to breakage.
在制备用于分析具有生物学意义的样品的气相色谱柱时,可以用镍管代替玻璃。对甾体、麻醉性生物碱、吩噻嗪和苯丙胺混合物在不锈钢、玻璃和镍填充柱上的分离情况进行比较,结果表明,与某些化合物在不锈钢柱上完全损失形成对比的是,在玻璃柱或镍柱上几乎没有观察到样品分解。镍柱易于制备、耐用、经济且不易破损。
