General Wet Chemistry/Physical Parameters
Major anion and nutrient analyses are performed either colorimetrically, titrimetrically, or potentiometrically. The laboratory is equipped with a Seal Analytical AQ-1 discrete analyzer for the analysis of ammonia. Other instruments available for the determination of nutrients and major ions include a Perkin Elmer Lambda 2 UV/ VIS scanning spectrophotometer, Orion and Fisher pH meters, and Orion specific ion meters, as well as associated balances, centrifuges, filtration apparatus, and glassware.
Ion chromatographic techniques are used for the determination of fluoride, chloride, nitrite, nitrate, bromide, phosphate, and sulfate in the parts per million range. The Dionex Model DX-600 ion chromatograph with PeakNet 6 Workstation provides analytical capabilities that conform to EPA Method 300.1 and ASTM Method D4327-84.
