spot analysis
Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. The development and popularization of the test is credited to Fritz Feigl〔("Spot tests in organic analysis" ), numerous editions〕〔(FRITZ FEIGL (1891-1971) ), Bull. Hist. Chem. 17/18 (1995) 31-39 (retrieved Feb. 21, 2013)〕
The test has been known in other languages as "Tüpfelanalyse" (German), "Analyse de Tâche" (French), "Análise de Toque" (Portuguese)〔 therefore in English literature a ''calque'' may be found: "touch analysis".
The method allowed for detection the substrate in a solution with dilution of 1:5,000 - 1:500,000,000.〔
The foundations of Feigl's work on spot analysis were the works of Hugo Schiff (the earliest publication about "spot test" was Shiff's detection of uric acid in 1859〔H. Schiff, ''Ann. Chim. Acta'', 1859, 109, 67.〕) and of Christian Friedrich Schonberg and Friedrich Goppelsröder on capillary analysis.〔
On the occasion of Feigl's 70th birthday the Chemical Society of Midland sponsored a symposium in 1952, attended by 500 scientists from 24 countries, in which all plenary sessions were related ot spot tests.〔
