Direct Probe EI-MS Testing Services

Impact Analytical provides direct probe EI-MS testing services on a wide range of materials for many different applications. Electron Ionization Mass Spectrometry is used to introduce low vapor pressure liquid solids to the mass spectrometer. Lower temperature requirements readily allow analysis of temperature sensitive compounds. EI-MS analysis can also be used for a wide range of samples. Direct probe EI-MS spectra are compared to our database for identification of unknown compounds and impurities.

We have experience characterizing many different samples by EI-MS. Some of the projects we have recently performed include:

  • Molecular characterization by EI-MS analysis
  • Contaminant identification by EI-MS and CI-MS
  • Identification of unknown compounds by direct probe EI-MS
