Johnson's J-QUANT® Nitrate 500 tests are used for determining the amount of nitrate in drinking water, process water and wastewater, as well as aquarium water. Routine use of fertilisers on farms can result in high levels of nitrate that ends up in food. Farmers, therefore, test to the nitrogen content in agricultural runoff to estimate how much fertiliser is required.
Benefits
Graduation: 0-10-25-50-250-500 mg/L Nitrate
100 strips/pk
Regular testing of nitrate levels in food is important e.g. potatoes and in preservatives as high levels can affect the quality and consumer health
Nitrate is derived from the decomposition of animals and plants
Nitrate is more frequently measured than ammonium in ponds and aquariums to maintain the quality of water
J-QUANTÆ Nitrate 500 ensures a rapid and safe way to check nitrate levels
High concentrations of nitrates may also be found in industrial effluent. The limit for the EU is 50 mg/l that can be carefully monitored with our J-QUANT® Nitrate 500 Test StripsJohnson's J-QUANT® Semi-Quantitative Test Strips are globally known for their accuracy and quality. They provide semi-quantitative results for ions, organic compounds, inorganic compounds and match the ever-demanding needs of a rapid test. Laboratory costs and time can be lowered by a substantial amount given the information they provide as a first-phase test.

Nitrite can provide an indication of contamination in the environment.
Aquarium, industry, wastewater and drinking water analysis is, therefore, an appropriate list of examples where nitrite measurement is possible.
Nitrite build up in aquacultures and fish farming through the breakdown of organic matter can impair the filtration units ultimately causing harm to the fish.
It is very important therefore to test for nitrites in this environment.
Peroxide based disinfectants usually come in concentrate form to save on shipping charges and require diluting before use.
Depending on the industry and the disinfecting purpose different concentration levels are required
Therefore these strips provide assurance that disinfection has taken place correctly by providing a semi-quantitative result
Appropriate for measuring inorganic peroxides in aqueous liquids Also suitable for disinfecting and rinsing solutions e.g. food technology, laundries and in swimming pool water
Measurement of total sulphite requires further sample preparation
Sulphite is utilised as an oxygen scavenger in process and boiler water, sulphite levels therefore need to be frequently monitored to prevent over treatment
Also used for food analysis e.g. fruit juice testing, sulphurated foods (e.g. fresh and dried fruits), shellfish, crustaceans and minced meat products which use sulphur based products to prolong shelf-life
Used to monitor production and quality of wine
Compatible with sulphite, bisulphite and metabisulphite ions
Useful for many applications, e.g. In chemical laboratories, organic solvents containing peroxide can be checked as they could explode upon heating.
Soak the test pad in the solvent sample then allow to dry
Add a drop of distilled/demineralised water and if the pad remains white then there is no peroxide present.
Testing for residual peroxide where high strength disinfectants are utilised for cleaning such as the dairy industry, drinking water, pools and hot tubs
Peracetic acid based disinfectants usually come in concentrate form to save on shipping charges and require diluting before use.
Depending on the industry and the disinfecting purpose different concentration levels are required. Due to its measuring range this test is suited to testing for the effective levels of peracetic acid in such disinfectants.
Therefore these strips provide assurance that disinfection has taken place correctly by providing a semi-quantitative result Peracetic acid is unstable therefore frequent testing is required.
Strips can be held in the specimen until the final colour change is observed, they can be used consistently with minimal risk in weakly buffered solutions
Colours can be matched accurately with the colour chart as there is no cross-contamination between the pads on the strip.
No specimen contamination
Slim packaging provides portability and safety
Nothing to prepare before use
Consistent batch to batch measurements against accurately printed colour charts
