Cannot put PEEK column ferrule on to the Active Preheater tubing - WKB7194

Article number: 7194

SYMPTOMS

  • Replacing column
  • Installing new ferrules on to Active Preheater
  • Ferrule will not slide onto tubing
  • Tubing appears damaged, no longer round

ENVIRONMENT

  • ACQUITY UPLC I-Class Sample Manager FTN
  • ACQUITY UPLC I-Class Column Heater - Active (CH-A)
  • ACQUITY UPLC H-Class
  • ACQUITY UPLC H-Class Bio
  • ACQUITY APC

CAUSE

End of the tubing on the Active Pre-heater is damaged.  Old PEEK ferrule has been tightened too many times with a wrench.  The repetitive over-tightening of the ferrule has warped the metal tubing of the active preheater, causing it to be too wide for the new ferrule to fit.

FIX or WORKAROUND

Replace the Active Preheater.

ADDITIONAL INFORMATION

The PEEK ferrule is only designed for a few uses per ferrule.  Ferrules should be changed out if leaking is observed when installing a column.
