HI-93731-03
The HI-93731-03 are reagents for the colorimetric determination of zinc. There are enough reagents for 300 tests to be used with a compatible benchtop or portable photometer.
The HI-93731-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. The method is an adaptation of the Standard Methods for the Examination of Water and Wastewater, 20th edition, Zincon method. The reaction between zinc and the reagents causes a brownish-green to a blue tint in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible benchtop or portable meter can be used to determine the concentration. The results will be displayed in mg/L (ppm) of zinc. These reagents are designed to be used with samples that have an expected range of 0.00 to 3.00 mg/L zinc. Ideal for use with the HI-96731 & HI-97731 portable photometers.
Tip for an accurate measurement
It is important that the sample does not contain any debris.
When the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.
Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.
Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.
After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
