Both qualitative and quantitative analyses are assigned to analytical chemistry as a part of chemistry. While qualitative analyses are focused on the identification of substances - the so-called analyte - quantitative chemistry deals with the determination of the quantity of a substance in the sample material.
Many quantitative analytical procedures still used today are based on methods from the 19th century. Instruments based on the methods of Kjeldahl, Dumas and Soxhlet, for example, are still being used today.
However, these modern instruments are now almost completely automated and therefore provide constant analytical conditions. Explanations of the manual methods, their range of applications and the automatic analytical systems that have evolved from them can be found on the following pages.
