Cyanide Test Kit, colorimetric, 0.002–0.03 mg/L CN ยี่ห้อ Sigma

DESCRIPTION

General description

Method: colorimetric with color card and comparator block with long test tubes 0.002 - 0.004 - 0.007 - 0.010 - 0.013 - 0.016 - 0.020 - 0.025 - 0.030 mg/l CN MQuant^®

The MQuant^® Cyanide test (formally MColortest™) measuresfree cyanide ions e.g. in

* Groundwater and surface water

* Drinking water and mineral water

* Waters from aquaculture

* Industrial water

* Wastewater and percolating water

* Electroplating wastewater

This test is not suited for seawater.

Method

Cyanide ions react with a chlorinating agent to formcyanogen chloride, which in turn reacts with 1,3-dimethylbarbituric acid in thepresence of pyridine to form a violet dye (König reaction). The cyanideconcentration is measured semiquantitatively by visual comparison of the colorof the measurement solution with the color fields of a color card.

The unique brilliance of the print and their fine colorgraduation allow precise analyses, even at the lower end of the concentrationrange.

Due to the long test tubes a sensitive measurement range canbe covered.

Using the refill pack 1.18457 containing all the reagents,the original test kit can be used for a very long time, making it aparticularly economical and ecological system.
