Service: Inorganic analysis of water samples


Inorganic analysis of water samples to comply with federal and provincial monitoring
requirements
 
LUEL is able to measure a variety of inorganic parameters on water samples including:
  • pH, Conductivity, Alkalinity, Acidity, Hardness
  • Dissolved Organic and Inorganic Carbon [DOC, DIC]
  • Nitrogen and Phosphorus [ Total, Dissolved or Available]
  • Total suspended solids (TSS), Total dissolved solids (TDS)
  • Total or Dissolved Metals
  • Anions (fluoride, bromide, chloride, nitrate, nitrite, sulphate, phosphate, etc.)
  • Cations (calcium, magnesium, sodium, potassium, etc.)
  • Cyanide [Total, Free, WAD]
 
Interesting applications of this analysis:
Samples have originated from a variety of university student research projects as well as from
external clients
 
University research samples include:
  • Pit lake water
  • Groundwater sources
  • Tailing pond water from abandoned mining sites
  • Peatland water
  • Toxicity test water using Lemna minor
  • Bioaccumulation study water using Eleocharis sp. and Carex sp.
  • Mine-impacted lake water
  • Eutrophic wetland water
  • Experimental extract water high in sulphate
  • Experimental extract water with expected high mercury levels
 
Other water samples are collected from:
  • Discharge, Effluent water
  • Factory cooling water
  • Receiving water
  • Natural water
 
You might be interested in this service if you:
Are investigating aquatic habitats water quality, monitoring of water quality
 
Where samples typically come from:
  • Lake and wetlands
  • Peatlands
  • Natural, pristine areas
  • Human-impacted areas of concern (mine sites, discharge areas)
 
How you need to prepare the sample before submission. Instructions on sample submission:
 
For metal analysis:
  • Samples may be collected in plastic or glass bottles and preserved with environmental
    grade nitric acid to pH<2
  • If left unpreserved, samples should be stored refrigerated and analyzed within 5 days
  • If boron analysis is required, glass containers CANNOT be used
 
For non-metal analysis:
  • Samples may be collected in glass or polyethylene sample bottles
  • Samples should be stored at 4C without preservative
 
What happens you your sample after we receive them. Analytical Methods and Technical Information:
  • If required, samples are filtered through a 0.45m filter before analysis
  • Conductivity is measured using an Accumet XL60 meter
  • pH, alkalinity and acidity are determined by titration using a Mettler Toledo DL53 titrator and autosampler
  • A 5ml aliquot of sample is analyzed using a Dionex DX-120 Ion Chromatograph, an AS40
    Automated sampler, an IonPac guard column and a IonPac analytical column
  • pH, Conductivity, Alkalinity, Acidity, Hardness
  • Dissolved Organic and Inorganic Carbon [DOC, DIC]; autoanalyser SKALAR with build
    in UV digestion system.
  • Nitrogen and Phosphorus [ Total, Dissolved or Available]; autoanalyser SKALAR with
    build in UV digestion and acid hydrolysis system.
  • Total suspended solids (TSS), Total dissolved solids (TDS); gravimetric measurement
  • Total or Dissolved Metals; Digestion for total metals and measurement done using ICP
  • Cations (calcium, magnesium, sodium, potassium, etc.); measured using ICP
  • Cyanide [Total, Free, WAD]; autoanalyser SKALAR with build in UV digestion and
    distillation system.
