Abstract

A multi-stage pressure regulator in which pressure is first reduced by a set ratio in one or more stages followed by an adjustable pressure output stage. The system of the present invention provides for distribution of the Joules-Thomson (JT) cooling effect between multiple stages. The present invention thereby provides a system to control pressure reduction and thus prevent condensation (and associated distortion of a vapor composition sample) of a gas due to J-T cooling effect.
