Supelco® Reflectoquant® Potassium Test, MilliporeSigma

Supplier: MilliporeSigma

The Reflectoquant Potassium test includes test strips and all necessary additional reagents and is used used for the determination of potassium ions in drinking water and mineral water, industrial water, wastewater, beverages and soils after sample pretreatment. Potassium ions react with dipicrylamine to form an orange-colored complex that is determined reflectometrically on the RQflex. For pre-testing a sample in an economic and quick way to estimate the potassium concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for potassium. Further quantitative determination methods can be found with our Spectroquant tests.

Supelco® Reflectoquant® Phosphate Test, MilliporeSigma

Supplier: MilliporeSigma

The Reflectoquant Phosphate test includes test strips and all necessary additional reagents. It is suitable for determining orthophosphate in wastewater, soil samples, fertilizers and food. In sulfuric solution orthophosphate ions (PO₄³⁻) react with molybdate ions to form molybdophosphoric acid. This is reduced to phosphomolybdenum blue (PMB) that is determined reflectometrically on the RQflex. For pre-testing a sample in an economic and quick way to estimate the phosphate concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for phosphate. Further quantitative determination methods can be found with our Spectroquant tests.

Supelco® Reflectoquant® Ammonium Test, MilliporeSigma

Supplier: MilliporeSigma

The Reflectoquant® Ammonium test includes test strips and all necessary additional reagents and is suitable for determination potentially harmful pollution in surface and ground water, which are caused by ammonium compounds. Depending on the pH level ammonia is formed, which is a potent toxin for fish. In agriculture the Reflectoquant® test strips can be used to measure the ammonium nitrogen content of various types of manure and compost after sample preparation. Ammonium ions react with a chlorinating agent to form monochloramine. This in turn reacts with a phenol compound to form a blue indophenol derivative that is determined reflectometrically on the RQflex®. For pre-testing a sample in an economic and quick way to estimate the ammonium concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant® test strips for ammonium. Further quantitative determination methods can be found with our Spectroquant® tests.

Supelco® Reflectoquant® Formaldehyde Test, MilliporeSigma

Supplier: MilliporeSigma

The Reflectoquant Formaldehyde test includes test strips and all necessary additional reagents. Formaldehyde is used as a disinfectant for surfaces, medical equipment and also as a raw material in binding agents, fixing agents or as a preservative. Formaldehyde reacts with a Triazole to form a purple-red tetrazine that is determined reflectometrically on the RQflex. For pre-testing a sample in an economic and quick way to estimate the formaldehyde concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant test strips for formaldehyde. Further quantitative determination methods can be found with our Spectroquant tests.
