Description
-
Gas furnaces were widely used in the 19th century and the first half of the 20th century for chemical analysis. In such devices, a long horizontal iron gutter is placed over the flames of numerous burners, covered with removable refractory tiles; on this gutter is placed a glass tube resistant to high temperatures. The substance to be analysed is placed inside the tube . By burning it, it is possible to determine its constituent elements and their quantity. Practically, a weighted amount of a organic substance to be analysed was put in a vessel of ceramic inside the tube, then the temperature of the tube was raised up to obtain gaseous products of C, N, H, then collected and analysed. The furnace shown in the photograph was used by Giacomo Ciamician in the chemistry laboratory at the University of Bologna in his research on chemical reactions in plants and the systematic study of the chemical action of light.
