Test Strips, Papers & Readers

Reflectoquant® test strips and reader for the rapid and cost-effective analysis of samples on-site or in-the-field

Test strips are a simple, effective, and low-cost analytical tool used for the rapid detection of an analyte in the field or on-site. A test strip coated with a chemical that reacts with the analyte is either dipped in the sample solution or the sample is loaded onto the test strip. The use of test strips for in-process detection is advantageous due to the ease of use and the high specificity offered by them. The results of test strips are either based on visual observation or the quantitative analysis using digital readers.

Test Strips in Food & Beverage Applications

Our selection of test strips for food and beverage applications includes MQuant® and Reflectoquant® test strips for visual or instrumental readout. These can be easily used anywhere and can significantly reduce the time and cost of the laboratory analysis. MQuant® test strips are used for the semiquantitative screening of glucose, lactoperoxidase in pasteurized milk, and detection of ascorbic acid and lactic acid in fruits, among others. The Reflectoquant® test strips are used in combination with the RQflex® 20 reflectometer for the easy and accurate quantitative measurement of different substances in food and beverage production as well as water testing. Reflectoquant® test strips are available to determine for instance the hydroxymethylfurfural (HMF) content in honey and fruit juices, total sugar content in potatoes, and nitrate content in vegetables.

MQuant® Test Strips for Semiquantitative Testing

MQuant® test strips offer semiquantitative detection of more than 30 different ions, organic, and inorganic compounds in the mg/L to g/L concentration range. MQuant® test strips feature minute amounts of the reagent on an absorbent pad mounted to a polyethylene terephthalate (PET) film. Next to the applications in food & beverage mentioned above, MQuant® test strips can be used for different semiquantitative measurements, including:

  • Potassium content of drinking water, mineral water, industrial water, wastewater, soil samples, wine, beer, and fruit juices
  • Arsenic in water, soil extracts, pharmaceutical products, prepared biological specimens, and liquid foods
  • Nitrite in boiler and cooling water
  • Tin and tin compounds in electroplating baths, reducing agents, stabilizers, catalysts, disinfectants, fungicides, and mordants used in the textile industry
