Principle:
Carrier gas hot extraction in inert gas atmosphere. The determination of oxygen and nitrogen concentrations in solid states is performed by carrier gas hot extraction in Helium atmosphere. The samples drop into the electrically heated furnace with graphite crucibles and are fused at temperatures up to 2700°C. Oxygen and nitrogen is released. Oxygen reacts with carbon forming CO and CO2 which is detected selectively by infrared absorption. Nitrogen is analyzed by means of thermal conductivity.
| Application: | Quantitative analysis of the oxygen and nitrogen content in metals, alloys, oxides, nitrides, carbides and functional materials |
| Determination limit: | µg/g up to main component |
| Accuracy: | about 0.5 – 5% relative standard deviation |
| Instruments: | ON-836 Analyzer / LECO Corporation USA |
Principle:
Carrier gas hot extraction in reactive atmosphere. Carbon and sulfur in solids are oxidized in oxygen gas at high temperatures in an induction furnace forming CO2 and SO2, which is detected selectively by infrared absorption.
| Application: | Quantitative determination of the Carbon and Sulfur content in metals, alloys, synthesized functional materials e.g. for lithium batteries |
| Determination limit: | µg/g up to main component |
| Accuracy: | about 0.5 – 5% relative standard deviation |
