Rosemount™ 770XA Gas Chromatograph

Rosemount 770XA Natural Gas Chromatographs provide the most accurate analysis of natural gas available in a field mounted gas chromatograph (GC). The 700XA features a design that increases analytical capability, maximizes ease of use, and widens the range of analysis options in a GC with an ambient temperature rating of -20 °C to 60 °C/ -4 °F to 140 °F. These enhanced features make the 700XA ideal for natural gas custody transfer and applications requiring advanced analysis such as C9+ (with hydrocarbon dew point and cricondentherm calculations) and C6+ with hydrogen sulfide (H2S).
