A bench-top elemental analyser that is capable of operating in three modes: CHN, CHNS and Oxygen, is fully automated, and includes a 60 position autosampler. CHN and CHNS are determined via the classical Pregl-Dumas method where samples are combusted in a pureoxygen environment. Oxygen determination is based on the classical Unterzuacher method which incorporates the modifications of Oita, Conway and Culmo where samples are converted to carbon monoxide following after pryolisation and reaction with a platinised carbon reagent. The analyser has an accuracy of <=0.3% and a precision of <=02%. The analytical range is from 0.001 -3.6 mgs for C, 0.001-1.0 for H, 0.001-6 mgs for N and 0.001 to 2.0 mgs for S and O.

[Wikipedia] Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O. Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.
