Inorganic Chemistry Unit
Unit Supervisor: April Williams
Comprised of the Nutrients and Wet Chemistry analytical groups.
Responsible for analysis of water samples for the parameters listed below utilizing a variety of analytical systems and procedures that include ion chromatography, flow injection analysis, fluorometry, spectrophotometry, and gravimetric analysis.
Nutrients Analytical Unit
Parameters | |
|---|---|
Ammonia Nitrogen (NH3-N) | Total Kjeldahl Nitrogen (TKN) |
Nitrate + Nitrite Nitrogen (NO3NO2-N) | Total Phosphorus (TP) |
Nitrite Nitrogen (NO2-N) | Nitrate Nitrogen (calculated) |
Orthophosphate (PO4) | Dissolved TP |
Dissolved TKN |
|
Note: Ammonia Nitrogen = NH3 + NH4; Total Nitrogen = TKN + NO3NO2; Organic Nitrogen = TKN – NH3-N | |
