Hvis kolonnen skal bruges for første gang, anbefales det, at den underkastes en konditionering. Man lader en svag gasstrøm passere gennem kolonnen og tænder så for gaskromatografienheden. Derefter begynder man gradvis at varme op til en temperatur på mindst 20 °C over driftstemperaturen (note 8).
If the column is being used for the first time, it is recommended that it be subjected to conditioning: passing a gentle flow of gas through the column itself, then switch on the gas chromatography unit and begin a gradual heating, up to a temperature of at least 20 °C above the operating temperature (Note 8).
