Paper Abstract

Metastable transfer emission spectronmetry (MTES) has been shown to be an extremely sensitive method for the determination of trace metals. In this work it was shown that MTES can also be used as a sensitive method for the determination of SO2 EDF and capillary sampling system were employed to determine the detection limit of the flowing afterglow system on the SO2 detection. The characteristic emission lines of SO2 (~a3B1~X1A1) are used to detect the concentration of SO2 and also can be used to identify SO2 from other S-containing molecules such as CS2. In addition S02 in a flowing tube has been detected down to 45μg m-3 by means of metastable N2 (A3ΣU+) energy transfer emission spectroscopy. The linear measurement range is from 0.045 to 0.8 mg m-3. The capability of metastable transfer emission spectroscopy in the quantitative determination of S02 has been evaluated. And the lowest detection limit of S02 in the dilution gas N2 has been confirmed to be about 10 times as much as that in the air because of the great consumption of N2 (A3Σu+) by 02.
