“…The microplasma is a further development of the stabilized capacitive plasma (SCP) [3,4] and is distinguished by an extremely simple construction and high robustness. It was designed for gas chromatographic detection of various non-metals, especially the halogens and sulfur, in the near-infrared spectral range (NIR).…”

The coupling of a near-infrared Echelle spectrometer (NIRES) with a gas chromatograph for element-selective detection is introduced. The miniaturized capacitive plasma device is operated at a frequency of 40.68 MHz and is mounted directly on an Hewlett-Packard HP6890 GC. First results with a mixture of halogenated standard compounds are presented and discussed in terms of the advantages and problems with this system.

When capillary gas chromatography (GC) is coupled with atomic emission detection (AED), mixtures of volatile and semivolatile organic compounds are first separated based on different retention in a capillary GC column, whereafter the separated compounds are introduced directly into a helium (or argon) plasma. The high temperature of this plasma results in atomization of the separated compounds followed by excitation of the constituent atoms. From the excited states, the atoms emit light of characteristic wavelengths which are monitored continuously during the chromatographic separation by an optical spectrometer. This results in element‐selective chromatograms, where all elements from the periodic table (except helium or argon) may be monitored selectively with a simple change of wavelength on the spectrometer. With the use of multichannel spectrometers, several elements may be monitored simultaneously resulting in multielemental detection. Both nonmetallic and metallic elements are detected with a very high selectivity. This enables environmental contaminants containing heteroatoms to be determined in dirty extracts without extensive sample cleanup. However, since detection limits (DLs) in GC/AED range from 1–100 pg s −1 , extensive analyte enrichment is often required prior to environmental analysis. Because the separated compounds are atomized within the plasma, only minor structural variations are observed for the detector responses. This, in combination with the multielemental capability, enables estimation of empirical formulas for each of the separated compounds, which may be utilized to support identification of environmental micropollutants. In addition, the structure‐independent detector responses enable simplified calibration for quantitative purposes because different compounds may be quantified based on a single elemental calibration curve.
