The K2 molecular spectra have been theoretically and experimentally investigated in the wave- length range between 550 nm and 1100 nm and at the temperatures between 650 K and 1100 K. Semi- classical theoretical simulations were performed using the m

A novel type of interface for gas removal has been developed for coupling a high-temperature/high-pressure online flow digestion system to an ICP spectrometry instrument. It consists of a porous polypropylene tube with an inner rod made of PEEK which

The isotopes 235U and 238U were simultaneously measured by absorption in a laser-induced plasma ignited by a Nd:YAG laser. Two separate diode lasers were used which probed almost the same plasma volume. The diode lasers were tuned to the absorption l

A small, low-pressure dielectric barrier discharge used as a detector for the analysis of halogenated hydrocarbons was studied by diode laser absorption spectroscopy of excited plasma atoms. The distribution, as well as diffusion of the excited atoms

The influence of oxytocin (OXY), sulproston (SUL) and acetylsalicylic acid (ASA) on L-alanine- (ALA), D-glucose- (GLU) or water- (H 2 O) uptake (maternal side) in the isolated perfused guinea pig placenta was investigated. Uptake was measured with a
