Description ServeSafe Quick Response QAC Test strip (Quaternary Ammonium Compounds) is calibrated at 0, 100, 200, and 400ppm, and give a response in just one second. This test strip can determine levels of up to 0-400ppm for hyamine- and steramine-type chlorinated amine disinfectants to confirm their cleaning power is at full strength. Quick Response QAC Test Strip Dip the test strip into the solution to be tested for 1-2 seconds. Compare the test strip to the color chart within 10 seconds. NOTE: These strips are guaranteed to accurately test: OASIS 146, Hyamine 35, Bardac 2250, Sysco (tablets). Precision Laboratories quat 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 pH indicators and buffering systems to create an environment where the test paper or strip reacts (develops color) proportional to the amount of analyte (QAC) present. The PL quat test papers and strips have color charts calibrated to solutions prepared from OASIS 146, an industry standard quat product. The performance of the papers and strips with alternate quat products should always be verified. In addition, any additives should be evaluated to see if they contribute to the “protein-error” effect.
