• Chloride Quantab Test Strips 300-6000 mg/L

Provide a quick, specific, on-the-spot test for measuring chloride content during oil and concrete production, and for determining chloride levels in critical industrial waters such as those used in cooling towers or cutting fluids. Simply place the Quantab® strip into the solution to be tested and get a specific chloride content measurement in about 10 minutes, plus a permanent record of the test. Easy-to-use Quantab® strips give accurate results without costly laboratory equipment.

Quantab® Chloride Titrators are convenient disposable devices for measuring chloride (NaCl or Cl) in aqueous solutions or dilute aqueous extractions of solids. All that is required to perform a titration is one Quantab® test strip and its calibration table. If chloride extraction procedures are required, instructions are provided on the package insert.

No other equipment or special training is necessary. Quantab® Titrators are self-acting and provide quantitative results that are easy to read and interpret. The completed test provides a permanent record.

Quantab® Titrator consists of a thin, chemically inert plastic sheath. Laminated within the sheath is a strip impregnated with a reagent. When Quantab® test strips are placed in a test solution, fluid rises up the strip by capillary action. The reagent reacts with the chloride ion in the solution and produces a white column in the strip. The height of this column is proportional to the total chloride concentration. Results are read by observing the number on the strip where the column peaks and then using the accompanying calibration table to convert the reading to ppm chloride ion. Approximate titration range is 0.005% NaCl (30 ppm Cl) to 1.0% NaCl (6000 ppm Cl). Normal dilution procedure allows testing to 10% NaCl (60,000 ppm Cl). Additional dilutions may be made to test higher levels.


  1. Remove a titrator from bottle and replace cap immediately.
  2. Insert lower end of titrator into solution. Do not allow solution to
    reach yellow completion string at top of titrator.
  3. Allow solution to completely saturate wick of titrator. Reaction is
    complete when yellow string turns dark.
  4. Note where the tip of the white chloride peak falls on the numbered
    Quantab® scale. This represents the Quantab® unit value.
  5. Refer to the table on the bottle to convert Quantab® units into
    salt concentration.

NOTE: Filtration of the sample solution may be needed to prevent obstruction of the titrator.



  • Problem Description:
  • How do the Quantab® test strips for chloride work?
  • Problem Solution:
  • When the Quantab® strip is placed in aqueous solutions, fluid rises up the strip by capillary action. When the strip is completely saturated, a moisture sensitive string across the top of the titrator turns dark blue.
    The strip contains silver ions, which combine with chloride in the sample to form a white column of silver chloride. The length of the white column (silver chloride) in the strip is proportional to the chloride ion concentration.
    Each lot of Quantab® strips is calibrated independently, so that the chart on the bottle where you find the chloride concentration may differ from a previous bottle.

  • Problem Description:
  • Why do the Quantab® Test Strips have a scale that goes to 10, but the numbers on the bottle don"t go up that high?
  • Problem Solution:
  • Each lot of Quantab® Test Strips for chloride is calibrated independently, therefore the highest chloride concentration for one lot may correspond to a different number on the strip for a different lot.
    Although most lots are not calibrated to go up to the top of the scale, the 0-10 scale on the strip can be divided into increments of 0.2, which is easy to read.

  • Problem Description:
  • What can interfere with the Quantab® Test Strips for chloride?
  • Problem Solution:
  • The Quantab® Test Strip reaction involves the formation of silver chloride on the strip from the combination of silver on the strip with chloride in the sample. Any anion (for example bromide, iodide, cyanide, and sulfide) which will react with the silver to give an insoluble precipitate may interfere with the Quantab® test and give a higher than actual result.
    Strong acids may also interfere, however the strips will work in caustic or extremely high pH samples. Nitrite and nitrate have no adverse effect on the Quantab® test.
    Quantabs will work in colored solutions as long as they are clear, however turbid solutions can clog the wick and cause very slow or incomplete reactions. Filter turbid samples before testing.
    Quantab® strips can be used in a wide range of temperatures.

  • Problem Description:
  • How can I extend the range of the Quantab® Test Strips for chloride? The number on my strip is above (or below) the numbers shown on the bottle.
  • Problem Solution:
  • 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.
