Cryoconcentration unit CCU-6

Application

Cryoconcentration unit CCU-6 (hereinafter referred to as CCU-6) is an integral part of an automated chromatographic complex based on a Crystallux -4000M gas chromatograph and is intended for quality control of helium 99,9999 and hydrogen 99,9999 for trace amounts of Ne, CH4, O2+Ar, N2, CO, CO2 и H2.CCU-6 concentrates gaseous impurities (Ne, H2, O2+Ar, CH4, CO и СО2) in helium and hydrogen in sorption columns at the temperature of liquid nitrogen, which are afterwards focused and desorbed and introduced into GC (equipped with FID-TCD and TCD- CCD detectors) to determine their qualitative and quantitative composition.

Weight, no more than kg 30

This installation is an improved typ, it is made for the determination of trace elements not only in helium, but also in hydrogen.

In UKK-6, liquid nitrogen is added automatically, which minimizes the dangers of contact with such a dangerous substance.

The detection limits of the installation are shown in tables 1 and 2.

Table 1 Detection limits for helium analysis.
