Chemetrics - K-1420D - Ammonia Hydroxybenzl Alcohol (HBA) VACUettes Kit (0-125 & 0-2500 ppm)

ITEM #: 12644600
Low-level ammonia nitrogen may be naturally present in water as a result of the biological decay of plant and animal matter. Higher concentrations in surface waters can indicate contamination from waste treatment facilities, raw sewage, industrial effluents (particularly from petroleum refineries), or fertilizer runoff. E x cessive ammonia concentrations are to x ic to aquatic life.
The Hydro x ybenzyl Alcohol (HBA) Method
In the ammonia test method that employs the Hydro x ybenzyl Alcohol chemistry, free ammonia reacts with hypochlorite to form monochloramine. Monochloramine reacts with HBA, in the presence of sodium nitroferricyanide, to form a green colored comple x . This test method measures the sum of free ammonia and monochloramine. Results are e x pressed in ppm (mg/L) ammonia-nitrogen, NH 3 -N.
The Hydro x ybenzyl Alcohol Method offers sensitivity similar to the Nesslerization Method and there is no generation of mercury-containing waste.
Kit comes in a plastic case and contains everything needed to perform 30 tests (e x cept distilled water): Refill, Comparator, Stabilizer Solution, Catalyzer Solution, Activator Solution, 25 mL sample cup, 3 mL syringe, dilutor snapper cup, sample cup top, micro test tube and instructions.
