Electron ionization (EI) is a unique and advantageous ionization technique typically employed in gas chromatography-mass spectrometry (GC-MS). Here are presented two different approaches to benefit from EI in liquid chromatography-mass spectrometry (LC-MS). The first EI-based interface exploits EI ...

ESI‑MS is electrospray ionization MS that produces ions using an electrospray where high voltage is applied to a liquid to create an aerosol. This method is used to determine the molecular weight of proteins, peptides, and other macromolecules [3]. This method is used at IDT over MALDI-...
Electrospray ionization mass spectrometry (ESI-MS) is nowadays one of the cornerstones of biomolecular mass spectrometry and proteomics. Advances in sample preparation and mass analyzers have enabled researchers to extract much more information from biological samples than just the molecular weight. In par...
