WebElectrospray ionization (ESI) ESI is a soft ionization technique used to ionize non-volatile or thermally labile samples amenable to analysis in the liquid phase such as those separated by liquid or ionic chromatography (LC or IC). The ESI source applies a high voltage to the liquid sample stream, generating a fine mist of charged droplets. WebA versatile tool for the analysis of polymers, insoluble samples and a broad range of compounds, which cannot be introduced into GC directly. Pyrolysis gas chromatography mass spectrometry (Py-GCMS) can be used to characterize most materials including insoluble and complex materials at trace levels often without any sample pretreatment …
