The Extorr RGA (partial pressure) mode requires a UHV vacuum system for operation. A small vacuum system pumped by a turbopump would be able to accomplish this. The nature of the gas to be sampled, and what you would like to find out about this gas, will determine the type of gas inlet you will need for this system. A great deal may be learned by using a simple capillary, aperture, or leak valve.
