HARDWARE AND SOFTWARE SYSTEM FOR CHROMATOGRAPHIC DETECTOR OF THERMAL CONDUCTIVITY IN THE MUSUN EXPERIMENT
Annotation
Basic technical and methodical approaches to the problem of chemical impurities measurements in hydrogen are described. Two ways of increasing sensitivity have been developed in the international nuclear experiment MuSun. The first one is a modification of the sampling procedure. The second one is improvement of the measurement system based on a chromatograph. These techniques provide precise measurements of the atmospheric impurities concentration in hydrogen at the level of 1ppb (part per billion).
