Identification of unknowns

The reliable identification of impurities or unknown compounds requires many years of experience. Some of our employees in the mass spectrometry department can look back on more than a decade of experience in this field.

For unknown compounds that can be measured by GC-MS, we use commercially available and proprietary in-house spectral libraries. For compounds measured by LC-MS, we use our accurate and high-resolution mass spectrometers. With the help of the orbitrap technology we can derive reliable suggestions for sum formulas of unknown compounds based on the accurate mass and high resolution of obtained spectra. Together with additional information about the product, we are able to make structural suggestions. Furthermore, we possess profound experience in the evaluation of fragment spectra, to make de-novo structural proposals from these data.
