This is an important work in the field of chromatography, describing the usefulness of color bands of different chemical reactions in porous materials for separation purposes, later of great use in clinical medicine. "In the 1860s, Christian Friedrich Schonbein and his student Friedrich Goppelsroeder published the first attempts to study the different rates at which different substances move through filter paper. Schonbein, who thought capillary action (rather than adsorption) was responsible for the movement, called the technique capillary analysis, and Goppelsroeder spent much of his career using capillary analysis to test the movement rates of a wide variety of substances. Unlike modern paper chromatography, capillary analysis used reservoirs of the substance being analyzed, creating overlapping zones of the solution components rather than separate points or bands." / Wikip. Friedrich Goppelsroder graduated from school in Basel, Switzerland, then the Les Auditore in Neuchatel, studying chemistry and physics with Prof. Charles Kopp. He studied with many leading figures of his time. He taught chemistry at Basel from 1861. Gedeon, Science and technology in medicine, p. 380.
