Iron Test Strips, colorimetric, 3–500 mg/L Fe(II) ยี่ห้อ Sigma

DESCRIPTION

General description

Method: Colorimetric, with test strips, 3 - 10 - 25 - 50 - 100 - 250 - 500 mg/L (Fe²⁺), MQuant^®

The MQuant^® test strips offer a very simple means of determining iron(II) in all aqueous media and on metal surfaces. They can thus be used to distinguish between ferrous and non-ferrous metals. Iron(II) ions react with 2,2′-bipyridine to form a red complex. The iron(II) concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. For a determination of Fe(III) it is necessary to treat the sample with Ascorbic acid first, to reduce Fe(III) to Fe(II). The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the iron concentration and a possible dilution factor prior to using a quantitative method such as a Reflectoquant^® or Spectroquant^® test.

We continue to demonstrate our commitment to our planet and a sustainable future by exploring ways to improve existing products in our portfolio. We have recently reviewed the current line of MQuant^® test strips to identify key opportunities to minimize impact without compromising on the product performance.This product has benefited from:

·      Test strip with reduction

·      Recycled aluminum tube

·      Digital instruction leaflet
