摘要：
Ion mobility spectrometry is a convenient method for the fast detection of gases under atmospheric pressure conditions. Using (63)Ni as ionization source, signals of different substances can interfere, which leads to hardly interpretable spectra. Two-photon laser ionization can overcome such problems. The advantages of this method are demonstrated by the detection of various kinds of hydrocarbons and amines in the trace gas concentration range.
