How to clear a partially blocked ACQUITY flow cell? - WKB1131

Article number: 1131

OBJECTIVE or GOAL

Clear a partially blocked flow cell so that back pressure returns to normal.

ENVIRONMENT

  • ACQUITY TUV / PDA

PROCEDURE

  1. Select a mobile phase that is likely to dissolve precipitates.
  2. Replace the column with a union, if necessary.
  3. Start flow at a very low rate, keeping the back pressure less than the 1,000-psi maximum back-pressure rating for the flow cell.
  4. Monitor the pressure. Reverse the flow to flow cell, if necessary ( i.e. put flow "IN" to "OUT" of the flow cell)
