摘要:

A simple glass device has been developed for experimental studies of molecular diffusion process in the systems methane/ethane/air with as well as without adsorption packing materials. Separations of methane and ethane have been carried out. The obtained results could be exactly described by the Rayleigh Equation concerning both molecular and isotopic separations.

摘要:

The nonsuppressed anion chromatography with indirect UV-detection is demonstrated as a suitable method for the trace-analysis in the secondary water system of nuclear power stations. Coated silica-based reversed phase material was used as ion exchanger. This material has a high chromatographic efficiency and selectivity. The used hardware allows the determination of chloride and sulfate with a detection limit of 0.8 ppb and a relative standard deviation of 20%.
