Abstract
The invention relates to the material, design and manufacture of a drift tube with an ion source region, particularly a miniaturized drift tube, for an ion mobility spectrometer to measure mobility spectra, particularly at atmospheric pressure. The invention proposes to use a high-performance plastic which can be injection-molded for the insulating main body for the drift tube and the ion source region. Polyphenylene sulfide (PPS) can be used for this purpose, for example.
