✦ Synopsis

A system is described in which a fraction of the helium gas being recovered from a group of cryostats is pumped through a test cell and returned to the recovery system. The monitor device responds within a few seconds and its output is used to operate solenoid valves that prevent dirty gas from contaminating the recompressed helium store. The recovered helium purity can easily be maintained at >99.9%.

## Abstract The potential of enantioselective capillary gas chromatography with modified cyclodextrins as chiral stationary phases for authenticity control is demonstrated for a selection of economically important essential oils. Adulteration can be easily detected in cases where enantiomerically p
