Replacing a Column
32 TSQ 9610 Hardware Manual
a. Disconnect the column from the column flowmeter connector.
b. Remove the clear plastic component, including its fittings, from the oven and set
them aside.
c. Close the GC door.
7. If necessary, condition the column before inserting it into the TSQ 9610 system. Column
conditioning consists of passing a carrier gas flow through the column heated to a
programmed temperature as described in the column manufacturer's instructions.
IMPORTANT Do not leave the source plug in the instrument for an extended amount of
time. Add a no-hole ferrule to the column during conditioning. Then remove the source
plug from the instrument. (You do not have to reinstall the ion source cartridge.) Reinstall
the source plug into the VPI before removing the no-hole ferrule.
a. If there are no conditioning instructions, perform the column conditioning by setting
a final temperature 10 °C–20 °C below the column's recommended maximum
temperature.
CAUTION INSTRUMENT DAMAGE: The material released from the column
(column bleed) during conditioning may contaminate the ion source if the
column is inserted into the transfer line during the high-temperature stage of
conditioning.
ATTENTION DOMMAGES À L'INSTRUMENT : les matières rejetées par la colonne
(ressuage de la colonne) lors du conditionnement peuvent contaminer la source
d'ions si la colonne est insérée dans la ligne de transfert lors de la phase à haute
température du conditionnement.
WARNING FIRE HAZARD: Do not use hydrogen as the carrier gas for
conditioning your column. It could vent into the oven and present an explosion
hazard.
AVERTISSEMENT RISQUE D'INCENDIE : n'utilisez pas d'hydrogène comme gaz
vecteur pour le conditionnement de votre colonne. Il pourrait être ventilé à
l'intérieur du four et présenter un risque d'explosion.
b. Run the slow temperature program that is recommended by the manufacturer. A
typical program would hold the column at 40 °C (104 °F) for 15 minutes, and then
ramp at 10 °C/min (50 °F/min) up to 10–20 °C below the maximum allowed
column temperature. Hold the column at this temperature for two hours.
CAUTION INSTRUMENT DAMAGE: Never exceed the column manufacturer's
maximum operating temperature.
