LIQUID CHROMATOGRAPH ANALYSIS METHOD AND LIQUID CHROMATOGRAPH ANALYZER

To provide a liquid chromatograph analysis method and a liquid chromatograph analyzer with which it is possible to measure a plurality of components included in a sample accurately and easily in a short time.SOLUTION: Provided is a liquid chromatograph analysis method for quantifying a plurality of components included in a measurement sample by a liquid chromatograph, including: a preprocess step for isolating each individual component from the plurality of components; and a quantification step for adjusting the measurement condition of liquid chromatograph of each component and performing quantification so that, with an elution time when each component is quantified by one time of liquid chromatograph while the plurality of components coexist being assumed to be T0, each isolated individual component can be quantified by liquid chromatograph in an elution time of less than T0 within ±10% of difference in elution time between individual components.SELECTED DRAWING: Figure 2 【課題】試料に含まれる複数の成分を液体クロマトグラフにより正確、簡便かつ短時間で測定できるようにした液体クロマトグラフ分析方法及び液体クロマトグラフ分析装置を提供する。【解決手段】測定試料に含まれる複数の成分を液体クロマトグラフで定量する液体クロマトグラフ分析方法であって、複数の成分から個々の成分を単離する前処理工程と、複数の成分が混在したまま一回の液体クロマトグラフで各成分を定量したときの溶出時間をＴ０としたとき、単離した個々の成分毎に、それぞれＴ０未満の溶出時間で、かつ個々の成分の溶出時間の差が±１０％以内で、液体クロマトグラフで定量できるよう、各成分の液体クロマトグラフの測定条件を調整して定量を行う定量工程と、を有する。【選択図】図２
