Equipment full name: 
Hewlett Packard 5890 Series II Gas Chromatography equipped with a flame ionization detector

Address: 237 Deike Building

Description: This gas chromatograph is used routinely to measure hydrocarbons, e.g methane and ethane in gas or water samples from streams or wells. This techique reproducibly measures methane concentrations as low as 0.1 µg CH4/Liter of water sample. This detection limit is lower, if not the lowest detection limit, reported by academic or commercial laboratories. 

Methane (CH4) or Ethane (C2H6) analysis - Cost Per Sample - Cost is based on analysis of 2 samples per hour; * Student Analysis, ** Lab Analysis
