  • Reflectoquant® Nitrate Test, Catalog No. 16971/1

    1. Method

    Nitrate is reduced to nitrite by a reduction agent. In the presence of an acidic buffer, this nitrate reacts with an aromatic amine to form a diazonium salt, which in turn reacts with N-(1-naphthyl)-ethylenediamine to form a red-violet azo dye, the concentration of which is determined reflectometrically.

    2. Measuring Range and Number of Determinations

    Measuring Range1) Number of Determinations
    5 - 225mg/l NO3-

    1.1 - 50.8mg/l N

    80.5 - 3.622mmol/m3 NO3-M or N
    50

    1) for conversion factors see section 8

    for measurement of concentrations > 225 mg/l NO3– see section 6

    3. Applications

    Sample Material:

    Groundwater, wellwater and drinking water
    Spring water and mineral water
    Industrial water,wastewater, percolating water
    Water in aquariums
    Pressed plant and fruit juices
    Food, animal fodder
    Soils and fertilizers

    This test is only conditionally suited for the determination of the nitrate content of seawater samples (false-low readings).

    4. Influence of Foreign Substances

    This was checked - in the case of interfering ions up to concentrations of 1,000mg/l - in solutions containing 100 mg/l and 0 mg/l NO3-. The concentrations of foreign substances given in the table lie below the limit at which the determination is interfered with:

    1)In cases in which the nitrite concentration is higher, eliminate nitrite ions acc. to section 6

    2)tested with Na-dodecyl sulfate

    3)tested with N-cetylpyridinium chloride

    4)tested with polyvinylpyrrolidone

    5. Reagents and Auxiliaries

    The analytical test strips are stable up to the dated stated on the pack when stored in the closed tube at +2 to +8°C.

    Package Contents:

    Tube containing 50 analytical test strips

    Bar code strip

    Other Reagents:

    EM Quant® Nitrite Test, Cat. No. 10007, measuring range 2-80 mg/l NO2-
    colorpHast® Universal indicator strips pH 0-14. Cat. No 9590
    Amidosulfonic acid GR, Cat No. SX1140
    EM Quant® Nitrate Test, Cat. No. 10020 or 10050, measuring range 10-500 mg/l NO3-
    Sodium acetate GR, Cat. No. SX0265

    Tartaric acid GR, Cat. No. TX0010
    Nitrate standard solution ready for use, 1,000mg/l NO3-, Cat. No. 19811

    6. Preparation

    • Extract solid sample materials by an appropriate method.
    • If nitrite is suspected, check the nitrite content using the EM Quant® Nitrite Test.
    If necessary eliminate interfering nitrite ions:

    To 5ml of sample (pH <10) add 5 drops of a 10% aqueous amidosulfonic acid solution and shake several times.
    • Check whether the nitrate content is within the measuring range. Use the EM Quant® Nitrate Test as a guide. Samples containing more than 225 mg/l NO3- must be diluted with distilled water.
    • The pH must be within the range 1-12. Check with universal indicator strips. If pH is lower than 1, buffer with sodium acetate; if greater than 12, adjust to approx. 3-5 with tartaric acid.

    7. Procedure

    Observe the instructions for the RQflex Reflectometer.

    The following applies to the Nitrate Test:

    Measurement procedure A.
    Stored reaction time: 60 sec.

    • Remove 1 analytical test strip and immediately reclose the tube.
    • Press START button of the reflectometer and at the same time immerse both reaction zones of the test strip in the sample solution (15-30·C) for approx. 2 sec.
    • Allow excess liquid to run off via the long edge of the strip onto an absorbent paper towel.
    • Approximately 10 seconds before the end of the reaction time, insert the test strip all the way into the strip adapter with the reaction zones facing the display.
    • Read off the result from the display in mg/l NO3-. The result is automatically stored.
    Note:
    • If the test strip is inserted into the adapter after the reaction time has expired, renewed depression of the START button may result in a false reading of the nitrate concentration.
    • At the end of each workday, cleanse the strip adapter thoroughly with water or ethanol.

    8.Conversions

    Units Required = Units Given x Conversion Factor
    mg/l NO3- or N mg/l NO3- 0.226
    mg/l NO3- mg/l NO3- or N 4.43

    9.Method Control

    To check analytical test strips, equipment and procedure:

    Dilute nitrate standard solution to 50 mg/l NO3- and analyze as described in section 7.
