Abstract
Processes during the cryotrapping procedure with the U-tube and U-capillary were investigated by 73As radioactive indicator and arsane trapping and volatilization efficiency were quantified. Trapping and volatilization efficiency of 100% were found in the U-tube as well as in the U-capillary. Relevant experimental parameters for the collection in the U-capillary (carrier gas flow rate, column length and capacity) were studied. Finally, miniaturized, simple and commercially available design of the cryogenic trap based on non-polar fused silica capillary successfully performed the collection procedure of arsanes.
