General description
Method: colorimetric with color card and sliding comparator 0.025 - 0.050 - 0.075 - 0.10 - 0.15 - 0.2 - 0.3 - 0.5 mg/l NO₂⁻ MQuant®
Application
- Clinical and laboratory features of urinary tract infections in young infants: Discusses diagnostic challenges and characteristics of urinary tract infections in infants, stressing the importance of accurate detection to guide treatment (Lo et al., 2018).
- Differentiating Kawasaki disease from urinary tract infection in febrile children with pyuria and C-reactive protein elevation: Focuses on differential diagnosis in pediatric care, which can influence the choice of nitrite tests for accurate and timely diagnosis (Han and Lee, 2018).
- Early features of Kawasaki disease with pyuria in febrile infants younger than 6 months: Addresses the overlap of urinary symptoms in Kawasaki disease, underscoring the utility of nitrite tests in complex cases (Yoon et al., 2018).
- Current practice on the management of pre-operative urine dipstick results in women undergoing gynaecological surgery in Wales: Reviews procedures related to pre-surgical care in gynaecology, indicating broader applications of nitrite testing in hospital protocols (Walker et al., 2019).
Analysis Note
Application testconforms
This MQuant® Nitrite test (formally MColortest®) is suitable for the colorimetric determination using the easy to use color card. The evaluation considers the untreated sample so even turbid and colored water samples can be analyzed without further preparation. Nitrite is naturally present in soil, water and food and must be closely monitored in drinking and ground water as well as in process, waste, or aquarium water.
The test can be used in:
Method
In acidic solution nitrite ions react with sulfanilic acid to form a diazonium salt, which in turn reacts with N-(1-naphthyl)ethylenediamine dihydrochloride to form a red-violet azo dye. The nitrite concentration is measured semiquantitatively by allocating the color to a value on a reference scale.
The test can be used in:
- Groundwater and surface water, seawater
- Drinking water and mineral water
- Aquarium water (freshwater and seawater), waters from aquaculture
- Food after appropriate sample pretreatment
- Soils and fertilizers after appropriate sample pretreatment
- Boiler and boiler feed water, cooling water
- Wastewater
- Electroplating wastewater
