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.
Claims15
An ion mobility spectrometer comprising a drift tube and an upstream ion source region, wherein at least one of the drift tube and the ion source region have a main body which is made at least in part of a polyaryl whose aromatic rings are linked via sulfur atoms or SO2 groups, and
- wherein a desorber chamber upstream of the ion source region has a main body which comprises the polyaryl and which is connected to a main body of the ion source region or which forms a shared main body with a main body of the ion source region.
A method for the manufacture of an ion mobility spectrometer, wherein at least one of a main body of a drift tube and a main body of an ion source region is formed by injection molding of a polyaryl, whose aromatic rings are linked sulfur atoms or SO2 groups, and
- wherein a desorber chamber upstream of the ion source region has a main body which comprises the polyaryl and which is connected to a main body of the ion source region or which forms a shared main body with a main body of the ion source region.
A method for the operation of an ion mobility spectrometer comprising a drift tube and an ion source region, wherein at least one of the drift tube and the ion source region have a main body which is made at least in part of a polyaryl whose aromatic rings are linked via sulfur atoms or SO2 groups, and at least one of the drift tube and the ion source region are operated at a temperature of between 100° Celsius and 220° Celsius.
