GPA Midstream School of Gas Chromatography

GPA Midstream’s School of Gas Chromatography is one of the best available worldwide. GPA Midstream’s Analysis, Test Methods & Products Specifications Committee manages, directs and conducts the school.

The training lasts one week with class from 8 a.m. to 5 p.m. Monday through Thursday, and Friday from 8 a.m. to noon.

What We Teach

The school covers basic gas and gas-liquid chromatography with an introduction to extended analysis. This is a hands-on curriculum directed toward chromatograph operators, measurement technicians and engineers involved with chromatography. The training will consist of lectures, demonstrations and chromatograph operation. The emphasis is on machine demonstration and operation. Both natural gas and natural gas liquid samples will be analyzed.

The five primary purposes:

  • To teach GPA Midstream chromatography procedures and calculation methods to industry technicians and chemists with hands-on instruction

  • To demonstrate that accurate and reproducible results can be obtained by chromatographic analysis

  • To provide related auxiliary information on fundamental chemistry, gas and liquid sampling, reference standard blends, safety practices related to pressurized cylinders, GC system components and operation, calculations, economics of extended analysis, portable chromatographs and contaminants in natural gas liquids

  • To provide limited troubleshooting of gas chromatography software/operation

  • To provide a laboratory demonstration of non-linearity

Lecture topics include:

  • Characteristics and Calibration of Detectors Used in Gas Chromatography

  • Column Technology and Types of Columns Used in Gas Chromatography

  • Computing Integrators and Gas Analysis

  • Fundamentals of Natural Gas Chemistry

  • Gas Calculation Procedures

  • Introduction to Gas Chromatography Application

  • Liquid Calculation Procedures

  • Condensate Analysis

  • Obtaining Natural Gas Samples and Laboratory Handling

  • Physical Constants of Paraffin Hydrocarbons as Used in Gas Calculations

  • Quality Control and Quality Assurance in Natural Gas Laboratories

  • Reference Standard Blends
