Tentative Standard for Compositional Analysis by Optical Spectroscopy

GPA 2119-20

In 2018, the GPA Midstream Association’s Alternate Test Methods Workgroup performed an evaluation of non-chromatographic technologies which have the potential to meet custody quality requirements for compositional analyses. It was determined that optical spectroscopy was a viable technology for compositional analysis of gas, NGL, and condensate. This tentative standard covers the determination of the chemical composition of single-phase gas or liquid hydrocarbon fluids using optical spectroscopy.
