Instrumental Techniques used in the ISL
The following documents describe some of the instrumental techniques used in the ISL-UofC.
34/32S BaSO4 or sulfide minerals by CF-EA-IRMS
13/12C and 18O/16O of carbonate minerals by CF-GasBench-IRMS
13/12C of Dissolved Inorganic Carbon (DIC) by CF-GasBench-IRMS
13/12C & 15/14N of organics by CF-EA-IRMS
13/12C of Natural Gas by GCC-IRMS
2H/1H of Natural Gas by HTC-IRMS
18/16O of solids by CF-HTEA-IRMS
15/14N & 18/16O of dissolved nitrate (TON) - "denitrifier method"
15/14N of dissolved ammonium - "diffusion method"
HD and 18/16O of water may be analysed by the following techniques (depending on sample quality, instrument demand and backlogs):
HD and 18/16O of water by CF-GB-IRMS
HD and 18/16O of water by Laser Spectroscopy (LosGatosResearch)
