Frequently Asked Questions

What are the available measurement ranges for zinc determination?
Two ranges are available: K-9903 for 0-3.00 ppm and K-9923 for 0-15.0 ppm zinc concentration.
What is the reagent mechanism for zinc detection?
Zinc reacts with zincon reagent in a buffered alkaline solution to form a blue complex, which is measured colorimetrically.
What standards and methods does this kit comply with?
The kit complies with APHA Standard Methods (21st Edition, Method 3500-Zn B, 2005) and ASTM D 1691-84 Test Method A for zinc in water.
How long is the shelf life of the reagents?
The reagent ampules are stable for extended periods. The indicator solution has an 8-month shelf life; we recommend using stock within 7 months.
Can the kit detect zinc in the presence of other heavy metals?
Interfering heavy metals can be eliminated by adding a masking agent. However, cyanide is not included in the formulation for safety reasons.
What types of samples can be tested?
The kits are suitable for testing dissolved zinc in drinking water, wastewater, industrial process water, and other aqueous samples.
