9.2 Cleaning and caring for the device
9.2.1 Handling the flow cell cartridge
An important aspect in handling your flow cell cartridge, is that you
should not touch the fiber optic ends with your fingers. Your finger may
leave a thin fat layer on the fiber optic ends, which drastically impairs the
flow cell’s and detector’s performance (see section „8.2 Possible prob-
lems and solutions“ on page 43).
To diagnose this issue, we recommend generating an intensity spectrum
(via your chromatographiy software under Diagnostics). Dirty fiber optic
ends result in little or no UV light (see below).
