FIELD: chemistry.
SUBSTANCE: bipolar ionisation source includes an ionisation chamber blown by a gas stream containing trace impurities of analysed substances, an ultraviolet source which irradiates the analysed gas, a device for separating and detecting ions connected to the ionisation chamber, a gas stream agitator which enables to convey positive and negative ions in the gas stream from the ionisation chamber to the device for separating and detecting ions. The ionisation chamber further includes an emitter which is blown by the gas stream and emits electrons under the effect of ultraviolet radiation.
EFFECT: invention widens the range of analysed substances which are detected using the disclosed non-radiation ionisation source, and also increases efficiency of ionising trace impurities of analysed substances.
