    • A method for reducing total sample complexity in native or digested biological sample(s), before analysis thereof by mass spectrometry, comprising the following steps: a) selecting a fraction from the entire native or digested biological sample(s) on the basis of pI-value, said fraction comprising native or digested sample representing a subset of or the entire substance population in the sample, said fraction being obtained by e.g. anion exchange chromatography, isoelectric focussing or chromatofocussing; b) separating native or digested sample substances from each other, wherein said separation is by cation exchange chromatography; and c) analysing aid substances by mass spectrometry. The invention also relates to a system for reducing total sample complexity in the above method, comprising a high capacity charge-selective column (anion exchange, isoelectric focussing or chromatofocussing) coupled to a MDLC work flow path comprising a cation exchange column and a RPC column. The system is followed by a MS/MS instrument.
    • 一种在通过质谱分析之前降低天然或消化的生物样品中的总样本复杂性的方法,包括以下步骤:a)基于pI从整个天然或消化的生物样品中选择一个级分 所述级分包含表示样品中的子集或整个物质群的天然或消化样品,所述级分通过例如 阴离子交换层析,等电聚焦或色谱聚焦; b)将天然或消化的样品物质彼此分离,其中所述分离是通过阳离子交换色谱法; 和c)通过质谱分析辅助物质。 本发明还涉及一种用于降低上述方法中的总样品复杂度的系统,其包括耦合到包含阳离子交换柱和RPC柱的MDLC工作流路的高容量电荷选择性柱(阴离子交换,等电聚焦或色谱聚焦) 。 该系统后面是MS / MS仪器。
