Hydrogen Peroxide CHEMets® used to to monitor sterilisation solutions in the packaging and sanitizing processes.

CHEMetrics’ Manganese water test kits employ the periodate chemistry that measures soluble manganese compounds but does not differentiate the various valence states.

Ideal for low- to medium-range colorimetric analysis of water quality

Titrets® test kits use reverse titration to quantify concentrations in aqueous samples

The Titrets® test uses a ceric sulfate titrant with ferroin indicator. Depending on the procedure used, this kit can determine H2O2 concentrations from 0.01% to as high as 20%.

Ceric sulfate is the titrant and ferroin is the end point indicator. The method is free from glycol interference in samples that contain up to 75% glycol, making it particularly applicable to systems that contain nitrite corrosion inhibitors. Results are expressed as ppm (mg/L) NaNO2.

The test kits utilize CHEMetrics Titrets® ampoules. Titrets ampoules use a reverse titration technique to measure analyte concentration levels (titrant volume inside the ampoule is fixed while the sample volume is varied).

Dissolved Oxygen in water test kits for environmental and drinking water applications (ppm range) employ the indigo carmine method. The reduced form of indigo carmine reacts with D.O. to form a blue product. The indigo carmine methodology is not subject to interferences from temperature, salinity, or dissolved gases such as sulfide, which plague users of D.O. meters.

The test kits for chlorine in water utilize a self-filling ampoule technology that reduces the user’s exposure to chemicals.
