Is it possible to extend the range of the QuanTab® Test Strips for chloride?
Extending the range of chloride test strips
The range for these strips cannot be extended above or below the limits shown on the bottle. The calibration is not linear and results will not be accurate outside of the stated range. Samples above the range can be diluted until the chloride concentration is in the measurable range. Results for diluted samples should be multiplied by the dilution factor. To measure samples below the lower limit on the strips, a different method such as titration should be used.
