Ion mobility spectrometer DTIMS 2030
The DTIMS 2030 was specially developed for coupling external laboratory gas chromatographs or GC-MS systems. It is characterized in particular by the fact that both an APCI source (Atmospheric Pressure Chemical Ionization) and a UV lamp are used as the ionisation mode. Thus, the spectrum of detectable substances is considerably expanded.
Commercially available GCs are very easily connected to the IMS via a heated interface. Thus, the advantages of existing laboratory systems such as autosamplers, special injectors or sample introduction systems can be used in conjunction with the high sensitive ion mobility spectrometry. Synchronisation with all commercially available GC and autosampler systems is possible.
Coupling with GC-MSD 6890
The coupling of a DTIMS with a GC-MSD 6890/5973 gas chromatography mass spectrometer, which are used in various laboratories, is shown as an example. The heated interface can be designed on the right or left side.
