Test Strips, MQuant®
MQuant® test strips by Merck are true high-tech products – mobile laboratories on just a few square millimeters of backing, that can easily be used anywhere. MQuant® test strips are suitable for the semiquantitative detection of ions, organic substances and inorganic substances.
They measure concentrations from as low as 1 or 10 mg/l right up to the g/l range.
Used for screening, MQuant® test strips give the user a quick summary of substance concentrations present in the sample. By providing a means of pre-selection, they can contribute significantly to reducing the time and costs for laboratory analyses.
Quality checks and in-process controls can be performed much more quickly. Used test strips are easily disposed of thanks to the minute amount of reagents they contain and the use of polyethylene terephthalate (PET) film as backing material.
MQuant® test strips allow more than 30 different identification tests and semiquantitative determinations to be performed. For some substances Merck even provides several different test strips to cover various detection ranges, so that in total more than 40 different MQuant® tests are possible.
The reaction zones are wetted by simple dipping into the solution being tested. The excess liquid is then shaken off. After the given reaction time has elapsed – a maximum of two minutes – the coloring of the reaction zone is compared with the color scale on the package to determine the concentration.
The standard pack contains 100 test strips in an aluminum tube fitted with a desiccant-filled stopper. User information is provided in 4 languages. We also offer this product in packaging specific to the application and customer requirements – see tab below. Strips that are individually sealed to improve their shelf life are available on request.
To assure the constantly high quality of MQuant® test strips Merck uses certified standard solutions to adjust and check the tests and the faithfulness of the reference colors. These standard solutions are directly traceable to primary reference standards from NIST and PTB.
MQuant® glucose test strips are an efficient way to conduct semiquantitative glucose screening. They are a great choice for food and beverage manufactures to assure the high quality of their products – and meet the strict quality standards, food and beverage products we all enjoy adhere to.
MQuant® glucose test strips deliver precise results quickly and easily wherever you are – leaving old-fashioned enzymatic determinations in the dust. No other product can make that promise to the food and beverage industry. At any facility supervising raw materials, production, or filling processes, they are your handy screening tool whenever you need to run a quick check on a sample – and don’t have the time to send it off to the lab.

MQuant® peroxidase test makes process control during milk pasteurization easier – without incurring high costs.
The product quality of milk depends heavily on successful pasteurization. Lactoperoxidase is an enzyme present in raw milk and it can only be denatured to peroxidase through ultra-high temperature processing (UHT), and not through simple pasteurization. For this reason, the European Union Regulation (91/180/EC) requires that peroxidase be detected in pasteurized milk as proof that the product has undergone gentle heat treatment.
With the qualitative MQuant® peroxidase test for the dairy industry, the enzyme can now be detected easily, fast and cost-effectively by using test strips. Quantitative testing is no longer required.
