Product Description

Low Level QAC Test Strip, 100ppm

Check for residual levels of QAC with the Low Level QAC Test strip (Quaternary Ammonium Compounds). This strip is calibrated at 10, 20, 50 and 100ppm. The color block for 10ppm is actually ≤10ppm, but the color change from 0-10 is so insignificant, it’s difficult to see the difference.

Instructions:

  1. Remove one test strip from the vial, being careful not to touch the test pad with your fingers.
  2. Dip the test strip into the solution being tested and move back and forth 5 times, then remove.
  3. Compare the test strip to the color chart after 10 seconds.

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 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 QAC test papers and strips have color charts calibrated to solutions prepared from OASIS 146, an industry standard QAC product.  The performance of the papers and strips with alternate QAC products should always be verified.  In addition, any additives should be evaluated to see if they contribute to the “protein-error” effect.
