保留参数，最好是Kovats指数，可以用来识别混合物的色谱分离组分，以及它们的化学衍生物。为了对峰进行可靠的关联，必须结合使用其他主要的光谱鉴定方法。有两种不同的应用Kovats索引的方法，即表匹配和/或I和ΔI值的增量预测。文中给出了两种方法的应用实例。详细讨论了保留增量的推导和有效范围，由于柱极性和仪器参数的原因，保留参数的推广使用直到最近才受到限制。就如何克服这些困难以及为获得准确数据而可能进行的更正和标准化提出了建议。
Retention parameters, preferably Kovats indices, can be used to identify chromatographically separated components of mixtures, and in addition, chemical derivatives thereof. For reliable correlations of peaks, combined use of other mainly spectroscopic identification methods is necessary. There are two different methods of applying Kovats indices which are table matching and/or incremental predictions of I and ΔI values. Examples for the application of both methods are given. The derivation and the range of validity of retention increments is discussed in more detail.The extended use of retention parameters was limited until recently because of a lack in data reproducibility due to column polarity and apparatus parameters. Proposals are made as to how these difficulties may be overcome and as to the corrections and standardizations which may be made in order to obtain precise data.
