Principle. A sample in a tin boat or tin capsule is weighed accurately and burned in a combustion tube with oxygen. The produced gas mixture (CO2, H2O, NOx, etc.) is introduced into the reduction tube, where nitrogen oxide is converted to N2 gas. Then the N2 gas is detected by TCD, on the other hand, H2O and CO2 are trapped on column. After …
