Abstract:

A sampling apparatus and air curtain guiding body (5). The sampling apparatus comprises: a chamber body (9) having a sampling inlet at a first end of the chamber body (9) for sucking in samples and a sample outlet (20) near a second end opposite the first end of the chamber body (9) for discharging samples. The chamber body (9) also comprises an air-importing inlet (7) on the wall of the chamber body (9) and an air-discharging outlet. The air-importing inlet (7) is configured to import cyclonic air flow into the chamber body (9), and the air-discharging outlet is configured to discharge air, so as to form, together with the air-importing inlet (7), a cyclonic air flow inside of the chamber body (9). The cyclonic air flow spirally traverses from the first end to the second end of the chamber body (9). In addition, a heating and temperature control system is provided for the chamber body (9), such that nonvolatile substance in the chamber body (9) can rapidly gasify for sample injection.
