BTU Analysis

Analysis of natural gas through gas chromatography by GPA 2261-13 and GPA 2172-09 for:

  • Natural gas from wellhead to plant fuel usage

  • Coalbed/coalmine methane

  • Landfill, digester and other alternative fuels

  • Identification of hydrocarbon gas components and inerts, gas density (specific gravity) and supercompressibility utilizing AGA8

Extended Analysis

New wells and certain emissions applications require sophisticated detail analysis of natural gas. GAS Analytical Services offers BTEX and C10+ analysis using the GPA-2286 method.

Hydrocarbon Dewpoint Determination

Hydrocarbon Dewpoint plots can be developed from the results of an extended analysis. These plots can be used for phase change predictions and help determine operational parameters.

Sulfur Quantification

Sulfur speciation (GPA-2199) provides breakdown of Sulfide, Mercaptan, and Disulfude compounds. Sulfur compounds are gaining attention from a corrosion perspective, and speciation may be necessary for pipeline and emmissions compliance. Total sulfur (ASTM D3246) provides total amount (ppm) of sulfur compounds in natural gas for applications where speciation is not necessary. Total sulfur is often acceptable for emmisions compliance.

Petroleum Labs

Our labs are equipped to conduct analyses on a variety of liquids including oil, fuels, and coolants. The liquids testing we perform is always done according to ASTM standards. Lab analysis is used to determine the quality of the fluid and to identify if the fluid has been contaminated and if so by what. Testing may include:

  • Viscosity

  • Wear Metals

  • Flash Point

  • Distillation

  • Freeze Point

  • IR Scans
