SAUNA II Lab system

 

Due to the fact that high sensitivity can be achieved with the beta-gamma detection technique, the SAUNA laboratory system can be suitable for re-analysis of xenon gas samples. The laboratory system is a manual system for quantification of the amount of stable xenon followed by an activity measurement. Because of the modularity, it is quite easily fitted to different laboratory needs.

 

Description


SAUNA II-L (Swedish Automatic Unit for Noble Gas Acquisition Lab) is a semi-automated system for analysation of radioactive xenon gas samples. The xenon sample is quantified, and radioactive isotopes are detected. The isotopes 133Xe, 135Xe, 133mXe and 131mXe are detected with a sensitive ß-γ coincidence technique.

 

SAUNA II-L transfers a gas sample from an archive bottle, quantifies the amount of stable xenon, separates other gases, and performs an activity measurement of radio xenon. The system consists of four modules: the archive transfer unit (ATU), the gas chromatograph (GC), the Sample Transfer Unit (STU) and the detection system. The whole process is controlled by a PLC and data is processed and saved on a PC.
