很久以来,气液色谱法就是分析很多种类有机化合物的一种重要技术。气液色谱法通常能对混合物中的一种或多种组份快速、方便地进行定性和定量分析。有机物分子适合于气液色谱分析的重要标准是:有机物要有足够的挥发性——能从色谱柱洗脱出来;在洗脱温度下对热和对化学品稳定,与柱填充物及构成气液色谱的任何材质不以任何方式发生反应。显然,只有极少数染料及其有关化合物能符合这些标准,应用气液色谱法分析染料的文献很少也证明
For a long time, gas-liquid chromatography is an important technique for analyzing many kinds of organic compounds. Gas-liquid chromatography often enables rapid and easy qualitative and quantitative analysis of one or more components in a mixture. Important criteria for organic molecules to be suitable for gas-liquid chromatographic analysis are: The organics should be sufficiently volatile - to elute from the column; thermally and chemically stable at the elution temperature, as opposed to column packing and makeup gas Liquid chromatography of any material does not react in any way. Obviously, very few dyes and their related compounds meet these criteria, and the literature on the analysis of dyes using gas-liquid chromatography rarely justifies
