Natural Gases

#127 - Natural Gas Analysis
This analysis is used to separate natural gases specified by the Natural Gas Processors Association in order to determine the chemical composition of these gases and similar gaseous mixtures.

On-line/Off-line automatic analysis of natural gas with N₂, CH₄, CO₂, C₂ to C₅ saturated hydrocarbons. All valves are automatically controlled. A simple change in the timing allows the user to select C₅⁺, C₆⁺, or C₇⁺ initial backflush. The system is based upon using either a Series 580 isothermal GC with TCD or a Series 600 temperature programmable GC with TCD and is set up for auto operation. Includes all GC hardware and software for BTU, compressibility factor, etc. Complete application documentation, method development and test chromatograms are included with the system.

#149 - Analysis of Natural Gas Standard on Megabore Capillary Columns Using a Gas Sample Valve or Splitter
The Series 580 Isothermal GC or the Series 600 Temperature Programmable GC can successfully be used in analyzing methane, ethane, propane, isobutane, butane, isopentane, and pentane utilizing wide bore capillary columns, a gas tight syringe, and either a gas sampling valve or splitter.
