ABSTRACT:
This disclosure is directed to a system for providing a sample. It incorporates and appropriately connected valve element working with a surrounding seat and housing. The valve element responds to pressure from the atmosphere which purges the valve element of remnants of a sample passing therethrough so that no trace constituents are left in the valve element. The valve element is a two position, three way valve element which is rotated, thereby permitting a purge gas to flow or not flow, and it rotated to another position permitting the sample of interest to flow or not flow. A sequence of operations is defined.
