The DPiMS QT probe electrospray ionization kit is attached to a quadrupole time-of-flight MS. The probe allows extremely small sample volumes to be selected and introduced into the MS unit for analysis. The DPiMS QT is a direct ionization interface unit that makes it simple for users to switch to ESI.

The qualitative analysis sequences for DPiMS QT and Q-TOF LC/MS were compared. Using DPiMS QT, it was possible to significantly reduce the measurement time in comparison to conventional methods using Q-TOF LC/MS.
Only a few dozen seconds are spent on DPiMS QT qualitative analysis. When performing qualitative screening analyses, the time before results are checked can be reduced, improving procedural efficiency.

Only a few dozen pL of the sample adheres to the probe after each sampling. There is no worry of contamination inside the mass spectrometer. Carryover can even be prevented by changing probes. Concentrated samples and samples of unknown concentration can be measured.
