The Determinator is capable of Nitrogen & Oxygen determination with great simplicity using latest technology and menu driven software. The operation of the analyzer is simplified with the use of PC based control systems which make the programming of all functions of the determinator extremely simple. Oxygen Nitrogen Determinator use two or single Detector system at a very high sensitivity Macro Thermal Conductivity Detector &/or Infra red detector capable to detect from 1 ppm to 2000 ppm using a nominal sample size of 1 gram for Oxygen and 1 ppm to 2000 ppm for Nitrogen using nominal weight of 1 gram.
