WebJan 19, 2016 · The B solvent is generally an HPLC grade organic solvent such as acetonitrile or methanol with 0.1% acid. The acid is used to the improve the chromatographic peak shape and to provide a source of protons in reverse phase LC/MS. The acids most commonly used are formic acid, triflouroacetic acid, and acetic acid. 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 ...

WebFast protein liquid chromatography (FPLC): FPLC is a system similar to high-performance liquid chromatography that is used to separate or purify proteins and other biomolecules from complex mixtures. The main difference between FPLC and HPLC is the standard working pressure. FPLC columns can only be used up to maximal pressures of 3-5 MPa. http://hiq.linde-gas.com/en/analytical_methods/liquid_chromatography/high_performance_liquid_chromatography.html
