This Information Applies To: Agilent LC Systems with G4212x / G7117x diode array detectors (DAD)
The Max Light cartridge flow cells have small internal diameter inlet and outlet capillaries. As a consequence, particles can easily block the capillary with some application/ practices, or using a dirty column, dirty solvents, or by flushing the system through the flow cell.
If it is leaking or if the intensity drops due to a contaminated flow cell, the cartridge needs to be replaced.
Steps to Follow
Tips: Perform a Cell Test and a Wavelength Verification Test before launching any analyses. It is performed before step 14 in case the cell's installation has to be adjusted.
