TOFWERKis a startup company specialized in the development and manufacturing of time-of-flight mass spectrometers (TOFMS) with a focus on high-speed chemical analysis for monitoring of transient processes down to the sub-millisecond time range. TOFWERK has a strong background in ion transfer interfaces to couple various ion sources to TOFMS, including high pressure ion sources and has successfully built, together with EMPA, a first GD-TOF prototype for thin layer characterization, capable of time resolving pulsed RF plasmas. TOFWERK's transportable TOFMS have been used in the field, on airplanes, and on trucks.
