Mobility spectra of the benzene are presented. We also discussed the mobility spectra at various concentrations and drift voltages. Detection limits are determined to be in the upper ppbv range. In the end,the advantages and possibilities of this technique are briefly discussed. Hits: 3467 Download times: 154 View Full Text    Download reader
