polarographn.

Brit.

/ˈpəʊlərəɡraf/, U.S.

/poʊˈlɛrəˌɡræf/

Origin: Formed within English, by compounding. Etymons: polarization n., -o- connective, -graph comb. form.

Etymology: < polar- (in polarization n.) + -o- connective + -graph comb. form. Compare French polarographe (1925; < English), German Polarograph (1935 or earlier). Compare polarogram n.

Chemistry.

An apparatus for automatic chemical analysis in which a sample solution is electrolysed at successively higher voltages and the resulting current plotted against voltage.

1925 Heyrovský & Shikata in Recueil Travaux Chimiques Pays-Bas 496 (heading) The polarograph.

1946 Nature 13 July 59/1 Iron can be determined satisfactorily on the polarograph if the solution contains triethanolamine.

1968 New Eng. Jrnl. Med. 25 Jan. 203/1 Arterial pO₂ was measured with the polarograph.

1974 S. E. Allen Chem. Anal. Ecol. Materials 400 Oxygen is the only dissolved gas of interest to biologists which can be readily determined on the polarograph.

1996 Biogr. Mem. Fellows Royal Soc. 42 159 Warren was a wizard with the polarograph, a tricky instrument in those days but invaluable for the quantitation of cystine in the cystinuric patients.
