Colorimetry using the Gutzeit method

The Gutzeit method for the colorimetric determination of arsenic was first described by the 19th century German chemist Heinrich W. Gutzeit (1845-1888).  In the original paper, silver nitrate crystals were used as the detector.  These were later replaced by a more practical paper strip impregnated with mercuric chloride and subsequently with mercuric bromide.  Stanton gives a detailed explanation.

Note that the test is often wrongly attributed to either of two other 19th century Germans: Max Adolf Guthzeit (1847-1915) and Ernst Wilhelm Heinrich Gutzeit (1863-1927).  E.W.H. Gutzeit was an agricultural professor at the universities of Königsberg and Halle, researching plant diseases, agricultural bacteriology and the dairy industry.
