一般描述

适合HPLC的水通常用作阳离子和阴离子色谱中等度洗脱的溶剂。此外,它还可作为组分用于制备标准储备溶液,以及在水浴氮气流下蒸发以在LC-MS-MS分析前浓缩样品。

应用

水可用于:
  • 作为溶剂,在细胞裂解过程中制备缓冲液。
  • 在HPLC–UV–二极管阵列检测中作为流动相的一部分,用于分离和检测分析物。

The analysis of amino acids by gas chromatography mass spectrometry (GC-MS) after their derivatization with N-(t-butyldimethylsilyl)-N-methyltrifluoroacetamide was investigated as an alternative approach for the determination of free (FAA) and combined amino acids (CAA) in aerosols. This technique showed excellent linearity
