The electrochemical behavior of nabumetone by a voltammetric technique and a novel colorimetric method based on chemical derivatization were also published.

This is a very common experiment that uses colorimetric method to find the end-point of the reaction.

The maximum absorbance at 540 nm for rosocyanine is used in this colorimetric method.

Acidification of the organic phase yields rubrocyanine, which can be detected by colorimetric methods.

Several colorimetric methods of test are available.

I believe that Hach Chemical Co. has a colorimetric method for chloride determination.

The Jaffe reaction is a colorimetric method used in clinical chemistry to determine creatinine levels in blood and urine.

In addition, there is at least one alternative colorimetric method (http://www.gfschemicals.com/chemicals/gfschem-2349.asp).

Grützner is credited with introducing a colorimetric method for determining the quantity of pepsin in a solution.
