Résumé
The analysis is carried out with a gas chromatograph fitted with a thermal conductivity detector. It can be operated at two temperatures, either at - 78 degrees centigrade or at ambient temperature. At ambient temperature, oxygen and argon are not separate and the method thus only allows the total content of these two gases to be determined. When the operations are carried out at - 78 degrees centigrade, these two gases are separated.
