Analysis Note
Packed columns continue to be used in multi-column, multi-valve configurations for the determination of BTU content in natural gas and natural gas liquids as described in Gas Processors Association (GPA) Methods 2261 and 2177, plus American Society for Testing and Materials (ASTM) Test Method 2597. This chromatogram is of GPA Method 2261, and uses three packed columns in a multi-valve configuration. Supelco is the world leader in packed GC column technology, with an extensive library of phases and supports.
