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
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.
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
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
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.
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
