Carbon, hydrogen, nitrogen,and sulfur are the basic elements of living nature. Their quantitative determination within the most versatile combinations and substances is the origin and essence of the ELEMENTAR manufacturing program. Through quantitative high temperature decomposition, solid or liquid substances are changed into gaseous combinations. The gas mixture is cleaned, separated into its components and through efficient detectors determined with a precision and accuracy of up to 0.1% relative.
Most important is the lare dynamic range of detection, from < 0.01 to 100%. This range is even possible when there is a great difference in relative concentrations (i.e. trace nitrogen in the presence of high carbon content). ELEMENTAR analyzers also feature very large sample size capabilities from < 1mg up to several grams. This wide range of applications with universal as well as special instruments is only achieved by ELEMENTAR. It has long since surpassed the classical applications from organic chemistry and pharmaceutical analysis, moving into the control of industrial products, geology, agriculture, environment protection, biotechnology, carbon and mineral oil analysis as well as authenticity and origin analysis.
