MS / IMS

In mass spectroscopy (MS) and ion mass spectroscopy, the HovaCAL VOC is used to calibrate these devices to different components in the ppm, ppb or ppt range.

The HovaCAL VOC is able to evaporate organic solvents and aqueous solutions and to further dilute the resulting calibration gas in the ppm range via a heated dilution unit into the ppb and ppt range.

Furthermore, several components can be dispensed independently of each other, thus enabling the generation of complex gas vapor mixtures, whose concentrations can be varied independently of each other. This makes it possible, for example, to investigate cross-sensitivities at trace levels. In addition, a defined humidity can be set, which can also be varied independently of the component concentrations. Thanks to the fact that all surfaces that come into contact with gas are heated throughout, surface effects are largely minimized. These could otherwise lead to extreme falsifications, especially at trace levels.
