GS Series Gas Samplers
Closed-Loop Sample Cylinder Systems for Gas Media
Spirare Energy's GS Series Gas Samplers are engineered for the safe, representative, and emission-free collection of pressurized gaseous media, toxic gases, natural gas, synthesis gas, and volatile vapor streams. Utilizing DOT/TPED compliant transportable sample cylinders connected via high-integrity quick-connect couplings, the GS Series guarantees 100% closed-loop containment without venting hazardous vapors into the atmosphere.
Available with single-handle mechanical valve linkages for foolproof operation, integrated pressure indicators, vent routing manifolds, and inert Nitrogen flushing, the GS Series purges sample takeoff lines prior to collection and depressurizes quick-disconnect lines before cylinder removal. All wetted components are manufactured in SS 316/316L, Hastelloy C-276, Monel, or with specialized SilcoNert / Sulfinert coatings for accurate trace sulfur and $H_2S$ analysis.
From basic manual cylinder panel stations to automated PLC-controlled gas sampling skids with fast-loop bypass filters and thermal enclosures, Spirare Energy delivers custom-configured GS Series gas samplers for oil & gas refineries, petrochemical complexes, LNG terminals, and hydrogen infrastructure projects globally.
