6 - Hydrogeochemistry-ICP/MS

Samples must be acidified prior to analysis.  Water samples are analyzed by Perkin Elmer Sciex ELAN 9000 ICP/MS, Perkin Elmer Nexion, Thermo icapQ or Agilent 7700.  A blank and two water standards are run at the beginning and end of each group of 32 samples. A reagent blank is run at the beginning of the group and every 10th sample is run in duplicate. If instrument suppression occurs, sample(s) affected are re-run at appropriate dilutions until response is normal. Dilution factors will increase by the same factor that samples were diluted. 

 

For analysis of marine waters or brines, detection limits will be correspondingly elevated depending on the dilution necessary to run the water samples. 

 

If % RSDs are required, choose option Code 6 EXPER (detection limits listed below) for 1-4 elements only.
