Johnson's J-QUANT® Peroxide test strips can quickly and reliably measure the level of peroxide in liquids. These strips provide consistent results with their easy to use method within 60 seconds of sampling. Peroxide is a general use disinfectant typically for the food and industry. With its exceptional antiviral, fungicidal and bactericidal properties it really is a useful cleaning agent.
Are an excellent choice for testing residual peroxide in production equipment levels after disinfection.
The test strip will show a value of 0 mg/l if there is no peroxide in the sample therefore the process can move forward.
The finished product is also tested for peroxide if it is made from a number of parts that have been disinfected with peroxide as a final check
Peroxide is commonly found in disinfectants and is one of the most effective oxiders available. It's disinfecting potency is greater than Chlorine (Cl2) or Chlorine dioxide (ClO2) Appropriate for testing peroxide in organic solvents (See J-QUANT Peroxide 100)
Johnson'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.
Our standard delivery is 3-5 working days (where products are available) Monday to Friday, excluding public holidays when you order by 2pm. Details of our returns and cancellation policy can be found in our Returns Policy & Section 11 of our Terms and Conditions. For more information please contact us on 01924 444 577 or Email Us.
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
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
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
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
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.
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.
