GPA Midstream Association



GPA Midstream’s Analysis, Test Methods and Specifications group has two main charges: 1) developing/maintaining analytical procedures and test methods that are needed by the midstream industry. Current emphases include a continuing advancement of the extended analysis methods for both gas and liquids. 2) Developing/maintaining product quality specifications for LP-Gas and natural gasoline, as well as monitoring and commenting on specifications for natural gas and CNG. Current emphasis is the identification, test methods and possible control of natural gas liquids contaminants.

Benefits of Committee Membership


Members have the opportunity to participate in the development, refinement and implementation of the midstream industry’s sampling procedures, specification test methods and analytical methods.


Members can also benefit from insight into midstream, refining and petrochemical industry trends and regulations and also from the opportunity to develop specifications for the midstream industry.


Networking opportunities are abundant with committee involvement, and committee members are able to share information and their own experiences related to sampling and testing procedures. This group also receives extensive exposure to industry standards and methods.



Products & Services


The committee manages, directs and conducts GPA Midstream’s annual School of Gas Chromatography, which teaches basic gas and gas liquid chromatography with an introduction to extended analysis and portable chromatographs. This is a hands-on school directed toward chromatograph operators, measurement technicians and engineers involved with chromatography.
