The peracetic acid test strips were developed for use in peracetic acid liquid preparations, not for peracetic acid generated using powders employing the "oxygen bleaching agent" approach.
Precision Labs Nitrate and Nitrite test strips measure results as nitrite and nitrate ions, not as nitrogen content (commonly referred to as nitrite-nitrogen and nitrate-nitrogen). It is important to know which result to report. Agricultural [...]
If you are preparing glucose standards in a lab to use with our Glucose Test Strips, in order for it to work properly, you must wait about 3 hours to allow mutarotation to occur. Solid [...]
The nitrate/nitrite test strip employs the well-known Griess reaction. Any nitrate present is first reduced to nitrite which then will turn pink due to the Griess reagents present. Both the nitrate and nitrite test pads [...]
The test strips are meant to detect ammonia and ammonium in water, but not combined ammonia compounds like chloramines. The test strip uses two pads in the test pad “sandwich” – the first pad creates [...]
Precision Laboratories QAC test papers and strips utilize an effect commonly referred to as the “protein-error of indicators” to quantify the QAC ppm levels. While first observed with proteins (thus the name), the technique utilizes [...]
A health inspector using QT-40 test strips compared their results to a customer using our QAC QR5 test strips, and the results were the same. The strips, however, are different in color and appearance. So, [...]
Our pH Color charts were developed using NIST-traceable pH buffers at 25°C. Colorimetric pH test strips do not offer “temperature compensation.” Care should be used when comparing results using test strips to those obtained with [...]
Yes. For example, or Chlorine paper (10-200ppm) will get a good reading, but the Mid-Level chlorine plastic strip (0-200ppm) will not work with trichloramines. The difference is explained by the "type" of chlorine that each [...]
No. The Phosphate test strip uses the Molybdenum Blue method and detects only orthophosphates. Tripolyphosphates must be converted to orthophosphate first to be detected. This can be accomplished by treating the sample with acid first, and [...]
