Modular design of a trap-and-atomizer device with a gold absorber for selenium collection after hydride generation

Popis výsledku v původním jazyce

A novel design of a device serving to trap hydrides and to volatilize the analyte to be detected by atomic absorption spectrometry, a modular trap-and-atomizer device, was invented to allow a simple replacement of the inlet arm which serves as the trap. A device with a gold wire absorber was employed for selenium collection. The relevant experimental conditions (hydrogen flow rate, trapping temperature and volatilization temperature) were optimized by using Se-75 radiotracer experiments and atomic absorption spectrometry experiments. A lossless Se collection was achieved. Two arrangements of the trap were tested to maximize the signal/noise ratio. A limit of detection of 7 pg ml(-1) was found for the optimum arrangement. Results of analysis of certified reference materials TMRAIN-04 and SRM 1643e provided good accuracy and precision. Interference of several hydride forming elements was characterized. The modular design appears to be promising for collection of other hydride forming elements.
