Product Spotlight The Thermo Scientific Natural Gas Analyzer analyzes Natural Gas Liquid (NGL) samples to determine BTU content as outlined in GPA Method 2186. The system, based on the Thermo Scientific ™ TRACE ™ 1310 gas chromatograph, analyzes a single NGL sample on two independent channels— C7+ regroup BTU and C1-C16 extended hydrocarbon detail.
