WATER ANALYSIS
Actlabs offers a range of ground, waste and drinking water testing in support of baseline studies site remediation, and other projects.
Inorganic Analysis
Code E6 ICP-MS is applicable only to natural waters with low total dissolved solid content (<0.05%). Any individual cations greater than the dynamic range of the ICP-MS will be reported as (>) unless the Overrange option is chosen. Samples submitted under all Code 6 packages will be analyzed on the supernatant portion of waters as received, acidified to pH <2 without filtration or digestion. Samples submitted as natural waters, but with elevated total dissolved solids (TDS >0.05%) will be charged as E6 MB. Analysis of waste waters and other solutions are available, but at varying costs. Please inquire. For hydro samples being analyzed by ICP-MS or by Ion Chromatography, please include field TDS/conductivity measurements, if available.

* Code E6 ICP-OES MB | Hydrogeochemistry ICP-OES for Marine Brines |
* Detection limits for samples with high dissolved solids such as marine waters or brines may be elevated by a factor of 10-1000.
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.

Ion Chromatography
Un-acidified water samples are analyzed using the DIONEX DX-120 Ion Chromatography System to determine and quantify a group of seven anions. This analysis is applicable to concentrations less than 75 mg/L for Cl, NO2 and NO3; less than 50 mg/L for F; less than 125 mg/L for PO4; less than 250 mg/L for Br and less than 375 mg/L for SO4. Samples exceeding this range (with high total dissolved solids) must be diluted to avoid over-saturation. Measurement uncertainty is evaluated and controlled by an appropriate quality assurance program, including the use of regular laboratory duplicates of samples and verification of the precision/calibration of the instrument through regular runs of various primary dilution standard solutions

Metal Speciation in Water
Our research activities over the last few years have allowed us to link the capillary electrophoresis and HPLC techniques to conventional ICP-MS or High Resolution ICP-MS. Using as little as 5 µg/L of solution, we can conveniently speciate a number of metals for their inorganic or organic metal species. This allows determination of a number of metal species sequentially. Actlabs can consult on the best ways to preserve samples for speciation analysis.
