Liquid use experience and contraindications 1. Acidic substances are suitable for negative ion detection, so the mobile phase is more alkaline to promote its dissociation,
LC-MS can acquire a total ion chromatogram by acquiring mass spectra. Since electrospray is a soft ionization source, there are usually few or no fragments,
1. What is the matrix effect?When analyzing drugs in biological samples by liquid-mass spectrometry (LC-MS)-based methods, some common extracts from the samples may have an
Liquid Chromatograph Mass Spectrometer (LC-MS) is an instrument that combines liquid chromatography and mass spectrometry. It combines the efficient separation of thermally unstable and high-boiling
