NEW APPLICATIONS OF CHEMILUMINESCENCE FOR SELECTIVE GAS ANALYSIS

Chemiluminescence (CL) is a powerful analytical tool for trace gas measurements. In this mini-review, we present reactions and spectra of ozone-induced CL for various compounds and techniques for detecting such CL. Next discussed are CL applications where real gas samples were successfully measured. Chemiluminescence monitoring has been used as universal nitrogen and sulfur detectors for gas chromatography and capillary electrophoresis. Chemiluminescence detection can be used as the basis of compact, affordable, and sensitive analyzers for real-sample analysis. Isoprene and sulfur compounds in breath and atmospheric samples have been successfully measured by coupling with a small collection system. Short-term (5 min) sorbent collection enhances the CL signal and considerably reduces interference. For sulfur gas analysis, methyl mercaptan and dimethyl sulfide can be separated on the same column that is used for collection. Waterborne arsenic is measured by automated arsine generation and CL reaction of arsine and ozone. In addition to gas-phase CL, more recent efforts towards the determination of gases by CL generated at solid/gas and liquid/gas interfaces are also discussed.

Rotational Spectrum of the AsH2 Radical in Its Ground State, Studied by Far-Infrared Laser Magnetic Resonance

The rotational spectrum of AsH2 in its ground X̃2B1 electronic state has been recorded using a far-infrared laser magnetic resonance spectrometer. The AsH2 radical was produced inside the spectrometer cavity by the reaction of arsine (AsH3) with fluorine atoms. Hyperfine splittings from both 75As and 1H nuclei were observed, and analysis of the spectra has yielded accurate values for rotational, hyperfine, and Zeeman parameters.

Size-selected nanocrystals of III–V semiconductor materials by the aerotaxy method

In this paper we present a fabrication route to produce size-selected III–V semiconductor nanocrystals via a simple, reliable, and efficient aerosol route. Since this approach includes the reaction of aerosol particles and a self-organized growth of a new compound, all in the aerosol phase, we call this process aerotaxy. Size-selected nanocrystals of different III–V compounds in a diameter range below 20 nm were fabricated using this method. Through the reaction of arsine with gallium droplets or of phosphine with indium droplets, GaAs and InP clusters were formed. Our approach opens the possibility to produce contamination-free and size-selected nanocrystals of compound semiconductor materials with considerable freedom in composition and size.

Rotational Spectrum of the AsH Radical in Itsa1Δ State, Studied by Far-Infrared Laser Magnetic Resonance

The rotational spectrum of AsH in its metastablea1Δ state has been recorded using a far-infrared laser magnetic resonance spectrometer. The AsH radical was produced inside the spectrometer by the reaction of arsine (AsH3) with fluorine atoms. Hyperfine splittings from both75As and1H nuclei were observed, and analysis of the spectra yielded accurate values for rotational, hyperfine, and Zeeman parameters.

Quantitative comparison of a tungsten and a tantalum cracker cell for epitaxy with arsine

The reaction of arsine in a gas source with a tungsten filament (WGS) was studied. A carefully tuned and checked mass spectrometer was used to obtain quantitative data. Maximum As 2 and As 4 production was observed at 800 °C and 630 °C respectively. This WGS was compared with a second gas source equipped with a tantalum wire. Operating conditions which yielded predominantly arsenic dimers were only achieved with the WGS. An explanation of the different yields in terms of the catalytic behaviour of the transition metals is proposed.
