结果发现，无论是重量百分比还是体积百分比都可以直接计算，因为在低浓度下，样品的比重非常接近1.00。表七比较了丙酮的气液分离层析和化学法测定结果。化学法用盐酸羟胺测定总羰基，w7h以丙酮计算。众所周知，其中一些样品含有大量的醛和酮，但每种情况下都需要一种特定的丙酮测定方法。除了常规应用之外，双色谱仪在快速采集大量样品、特殊的中试工厂研究以及“这是什么？”方面发挥了巨大的作用。样本。
It was found that either weight or volume per cent could be calculated directly, because at low concentrations the specific gravity of the samples was very close to 1.00. Table VII compares the results obtainedby gas liquid parti-tion chromatography and chemical method for acetone. The chemical method determines total carbonyl by hydroxylamine hydrochloride, w7hich is calculated as acetone. It was known that some of these samples contained traces of numerous aldehydes and ketones, but a specific acetone determination wras desired in each case. In additionto the routine applications, the dual chromatograph has been invaluable in trouble shooting large number of samples rapidly, special pilot plant studies, and “what is it?” samples.
