CHEMetrics Nitrite Test Kits

Nitrite is an intermediate ion in the nitrogen cycle of the chemical formula (NO₂^–). It is formed during the decomposition of organic matter but readily oxidizes to form nitrate (NO₃^–). Due to this rapid oxidative conversion, nitrite is a very short-lived ion and is typically found in low concentrations naturally. Nitrites enter water naturally from mineral deposits and organic decay or artificially from fertilizer run-off and sewage. As a short-lived ion in the nitrogen cycle, measurements of nitrite provide valuable information about the nitrification and denitrification process in a system.

In environmental applications, nitrite testing can help determine if a body of water is enriched with nutrients signaling it is approaching a eutrophic state. Eutrophication can lead to toxic algae blooms which deplete oxygen. The resulting hypoxia damages the ecosystem and can cause fish or shellfish kills. By measuring nitrite at different watershed locations, pollution point sources can be identified before an algae bloom begins.

Vacu-Vials Kits are instrumental kits that come in a cardboard box and contains everything needed to perform 30 tests (except distilled water): 30 ampules, Stabilizer Solution, Catalyzer Solution, Activator Solution, 25mL sample cup, 3mL syringe, ampoule blank, and instructions. These kits require the use of the V-3000 photometer or a spectrophotometer capable of accepting a 13mm diameter round cell (sold separately).

CHEMets Kits are visual kits that come in a plastic case and contains everything needed to perform 30 tests (except distilled water): 30 Ampule Refill, Comparator, Stabilizer Solution, Catalyzer Solution, Activator Solution, 25mL sample cup, 3mL syringe, and instructions.

Visual Titrets Test Kits feature a reverse titration to replace and simplify lengthy drop count test procedures. These kits utilize a ceric sulfate titrant with ferroin indicator.  Each kit includes 30 self-filling ampoules, titrettor, sample cup, and instructions, all packaged for convenient field or lab use. With clear incremental readings across the full range, this trusted system ensures accurate, efficient results for water quality professionals and industrial applications without the need for complex lab equipment.
