Cautions

1. The Nickel(DPM) PACKTEST allows to measure dissolved Ni2+ ions concentration. If you wish to

measure total nickel fraction including suspended particles, you must process samples in order

to dissolve solid phases.

2. The normal pH range is 4 - 9. If necessary, adjust the pH with diluted sulfuric acid or sodium

hydroxide solution.

3. The reaction color becomes stronger than 10mg/L of standard color when the nickel standard

solution is 100mg/L.

When the standard solution is higher than 200mg/L, a red precipitate will occur, and the reaction

color becomes colorless.

If you suspect a high concentration, make a dilution of your sample.

4. Ensure that PACKTEST tube is filled up to the half.

5. Partially undissolved reagent will not affect the measurement.

6. Keep sample temperature in the range 15°C - 40°C. Lower temperature necessitates longer

reaction time.

7. Read the test under a daylight type lamp.

8. Put the line back into the aperture after use to prevent reagent spilt.

Standard colors were determined from standard solutions. However, coexisting substances will cause

inaccurate results. The list below reports ion concentrations under which ones interferences are
