WebThe Principle of Tandem Mass Spectrometry Tandem mass spectrometry is based on coupling mass spectrometers together in a series to analyze complex mixtures. The method uses two mass filters arranged sequentially with a collision cell between them. The filters can be used in static or scanning mode to select a particular mass-to-charge (m/z ... Webdetection feature of ion chromatography is also what makes it one of the most compatible and useful form of liquid chromatography front-end to be coupled with MS. To implement suppression (also known as «desalting» in the MS field), the effluent of the IC separation column passes through a membrane device called a suppressor. The Figure 2.
