Safety in seconds – Precise nitrate monitoring
High levels of nitrate in animal feed can cause it to accumulate in milk, where it is converted into nitrite. Nitrite is particularly toxic to infants. To ensure food and baby food are safe, nitrate and nitrite levels must be strictly monitored. Our QUANTOFIX test strips make monitoring fast, easy and reliable. Find all the necessary information on analysing dairy products in our applications section.
Excellent precision: QUANTOFIX Nitrate 250
Thanks to their extra-large test area, our QUANTOFIX Nitrate 250 test strips deliver highly accurate results, as our comparative study shows. The measurement inaccuracy is less than 5%! Interested in testing for nitrite as well? QUANTOFIX Nitrite 25 is the perfect complement.
For details on the precision of QUANTOFIX Nitrate 250, please refer to the comparative study. See for yourself!
The 2-in-1 solution: QUANTOFIX Nitrate 100
With two test fields, you can measure both nitrate and nitrite simultaneously using just one QUANTOFIX Nitrate 100 test strip. This saves you both time and money!
Applications for Nitrate Monitoring in Dairy Products
Dairy products are typically viscous and opaque, which is why photometric methods often fail. That’s why you should rely on test strips!
With a slightly modified procedure, samples can be analyzed despite their high fat and protein content. Read more about each application in the corresponding section:
