General maintenance of O-rings
and scraper seal
Optimal function of AxiChrom columns requires that the O-rings, scraper seal and snap
rings are intact and in good condition.
Make sure that the O-rings are checked regularly and when appropriate replaced with
new ones. GE Healthcare recommends that if during maintenance and service an O-ring
is removed from its position on the column, then it should always be replaced. Otherwise,
it is recommended that the O-rings are replaced once a year.
The scraper seal on the adapter bed support shall be regularly checked for scratches
and other damage (see Servicing the stainless steel adapter bed support, on page 112or
Servicing the plastic adapter bed support, tubing and rod top , on page 124). On sign of
any damage the scraper seal shall be replaced. Otherwise, it is recommended that the
scraper seal is replaced after ten packing operations or at least once per year,
whichever comes first.
The snap ring that holds the plastic bed support shall be replaced when changing the
bed support.
