Effect of temperature on direct chemical vapor generation for plasma optical emission spectrometry: An application of programmable temperature spray chamber

Concerning DCVG-PN-PTSC-MIP-OES system, a predominant role of the analyte vapor generation efficiency on the analytical performance was found rather than increased analyte transport efficiency. The beneficial effect of the analyte vapor release is enhanced, however, by combination with reduction of the water loading to the plasma by PTSC cooling. The performance of the DCVG-PN-PTSC-He MIP-OES system was evaluated by determining LODs, which are 20, 14, 19, 2.5 and 8 μg L− 1 for As, Se, Sb, Hg, and I, respectively.
