Resumo: As the analyst responsible for determining inorganic gases and light hydrocarbons, new chemical engineer Jaroslav Janák developed a gas chromatograph using carbon dioxide as carrier gas, columns containing activated charcoal or silica gel for the separation, and a volumetric detector. In 1952 he solicited a patent on his invention and observed various industries applying his system.
