NOAA/GMD is the WMO/GAW Central Calibration Laboratory (CCL) for N2O, CO2, CH4, and CO. In support of GAW, GMD offers calibration services for these gases for a modest fee. The HATS Group of GMD will also calibrate compressed gas standards to NOAA/GMD scales for CFCs, HCFCs, etc. Calibrations are performed through a Memorandum of Understanding (MOU). To initiate an MOU, please contact Brad Hall or Duane Kitzis.
We also prepare tertiary standards at near-ambient mixing ratios for other organizations performing research related to our lab's mission. The cost of a standard varies with the cylinder type and level of complexity. For cylinders filled with natural air (Niwot Ridge, Colorado) fees are listed below. Note that the HATS Group operates a different Rix compressor than the CCGG Group . Our compressor has been modified to reduce contaminants that can interfere with gas chromatograhy with electron capture detection.
For custom mixtures or variations, please contact Brad Hall (+1 303 497 7011)
