Product: 090070 Chromium (VI) Test Kit for water fast detection
Usage:
This product can be used in analysis of chromiun(VI) in drinking water, its source water, and residual chromiun(VI) in electroplating water, metal products, electronic components and etc..
Features of product:
Quick and easy
Operating in accordance with the instructions, users can complete the chromiun(VI)test independently without specialized training. 5 minutes is enough to complete the analysis of one water sample.
Accurate and reliable
Determination results with this method are in accordance with the results with the standard method. It can be used as an alternative method to the standard method.
Quantitative packing
The kit can be used for 100 times. It is small, light and easy to carry.
How to use?
Chromium (Chromium Six )
Test Specification
1. Chromium (Six) test in water sample
a) Fill a clean test tube with water sample to the 15-mL mark. Add the contents of one Chromium Reagent, cap the tube and shake to dissolve, stand for 15 minutes.
b) Open the cap, place the tube in 1 cm above the blank of standard card, compare the color from top to bottom, the standard color level has the same color as observed from the tube shows the concentration of Chromium in the water sample.
2. Chromium test in solid sample
a) The Chromium in a certain amount of solid sample are transferred to the water phase by the boiling at first.
b) Then, the content of Chromium in water phase can be detected according to the method 1.
c) At last, the concentration of Chromium in the solid sample can be calculated .
Package:100 test / box
1.R & D team to provide technical support.
2.Provide packaging, labeling OEM customization.
Q1: When doing hardness testing of water samples ,why color keep unchanged after adding 100ml of water ?
A1: The hardness of the water sample may belong to low hardness,it out of testing range range of reagents, lower hardness reagent is recommended to be used.
Q2: When doing chlorine (or ozone, total chlorine) testing of for water samples,the longer time, the deeper the color, and why?
A2: Because the containing DPD reagent may react with the air oxidation, it is proposed in strict accordance with the test instructions, to control the reaction time.
Q3: Why the water sample shows pink after adding DPD chlorine (or total chlorine, ozone) reagent ,and then faded to become colorless?
A3: The reason may be that the concentration of chlorine (total chlorine, ozone) in the water is too high, dilution is recommended before testing.
