Abstract

A probe injection dual-microplasma spectrometer is evaluated as a low-cost alternative for the determination of extractable organic chlorine and bromine (EOCl and EOBr). The system consists of two 350 kHz plasmas sustained in the same stream of helium and a probe for sample application in the interplasma region. The sample was applied with a microsyringe into a small cup on the sample probe. Subsequently, the extraction solvent was gently evaporated, and the sample cup was pushed into the interplasma region. The first plasma was in direct contact with the sample probe and served to rapidly vaporize the sample material. The vaporized sample was then transferred to the second plasma, where atomic emission was measured for the determination of EOCl and EOBr. For both Cl and Br, 120 pg detection limits and 1000:1 halogen-to-carbon selectivities were obtained, and responses were linear over 3 orders of magnitude.
