Each kit contains 30 ampoules for 30 tests with the exception of COD vials (also available in larger sizes). Units 'ppm' are equivalent to 'mg/l'. All CHEMetrics multi-analyte photometers can of course measure any type of compatible cuvette or vial, designed for photometric analysis, to show either absorbance or percent transmittance readings.
2010/10/14 · A COD reactor/heating (150 C) block and a colorimeter are turned on so that both instruments are allowed to stabilize. Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on expected results. Both ranges
Other water quality parameters collected once each summer include pH, conductivity, alkalinity, color, nitrate + nitrite and total Kjeldahl-N. Calcium and magnesium are sampled once every 5 years. Please check the SWIMS database to determine which lakes are due for Ca and Mg sampling.

2018/1/6 · This work studied the anaerobic digestion of brown juice, a liquid residual stream generated from biomass fractionation in a green biorefinery. Biomethane potential batch tests and inhibition studies of brown juice were performed during continuous processing in an upflow anaerobic sludge blanket reactor. Prolongation of the lag phase in the batch tests with increasing substrate/inoculum ratio
