摘要： A multi-stage pressure regulator system. The system of the present invention provides for distribution of the Joules-Thomson (J-T) cooling effect between multiple stages. In the preferred embodiment of the present invention, the pressure is first reduced by a set ratio in one or more stages followed by an adjustable pressure output stage. 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. The system of the present invention is particularly suitable for use placement (via, for example, a probe) within the source gas supply containment vessel, pipeline or the like, so that pressure reduction occurs at or near isothermal conditions, further lessening the likelihood of J-T condensation.
