NATURAL GAS FUEL ANALYSIS
McHale offers in-house, mobile (both domestic and international), and on-site Natural Gas Chromatography capabilities. In addition, we conduct natural gas fuel analysis and deliver reports that follow ASTM-D1945 standards.
Furthermore, McHale performs calibration checks at both the beginning and end of each analysis day, thereby ensuring the results remain within accepted tolerances. As for turnaround time, our standard in-house lead time is typically five (5) to six (6) business days; however, we also provide expedited services for those requiring faster results.
ASTM-D1945
Standard Test Method for Analysis of Natural Gas by Gas Chromatography
ASTM D1945 defines a standard test method for analyzing natural gas using gas chromatography. It outlines procedures to determine the composition of gases such as methane, ethane, propane, butanes, pentanes, carbon dioxide, oxygen, nitrogen, and other trace components.
The power and natural gas industries rely on this method for quality control, custody transfer, and compliance with specifications. It provides guidelines for handling samples, setting chromatographic conditions, and calculating gas compositions to determine properties like heating value and specific gravity.
What is gas chromatography?
A gas chromatograph (GC) separates, identifies, and quantifies components in a gas mixture. It operates by injecting a sample into a carrier gas (such as helium or nitrogen), which moves through a column coated with a stationary phase. Different components travel through the column at different speeds based on their chemical properties, allowing for separation.
A detector at the end of the column measures the compounds and provides data for concentration analysis. Industries like oil and gas, pharmaceuticals, environmental testing, and food safety rely on gas chromatography for precise chemical analysis.
