Evaluation of a 13.56 MHz capacitively coupled plasma as a detector for gas chromatographic determination of organotin compounds

Abstract

A demountable, parallel plate, capacitively coupled plasma source operating at 13.56 MHz has been developed as a gas-chromatographic detector for the determination of organotin compounds. The effect of operating power and gas flow-rate on analyte emission intensity has been measured and spatial emission characteristics of the plasma have been evaluated. The detection limits for Me₄Sn, Me₃SnCl and Pr₄Sn were 0.079, 0.190 and 0.168 ng s^–1, respectively.
