About

five technologies GmbH is an R&D company which designs instruments and software for analytical measurements. We specialise in the development of Time-of-Flight mass spectrometers (TOF-MS) for the analysis of volatile and semi-volatile organic compounds. Our team covers everything from ion optics to fast speed electronics and SW & firmware development. We also develop algorithms for chemometric data evaluation techniques.
