Do not touch the cell windows. If you touch a window, clean it with
isopropyl alcohol (IPA) and a clean lens tissue.
Strong bases can etch the fused silica windows of the flow cell. If the
mobile phase is a base, make sure the mobile phase concentration
does not exceed 0.1 M. If the concentration of the base is greater than
50 mM, disconnect the separator column and flush the system with
deionized water for 5 minutes at 1.0 mL/min immediately after the
analysis. If strong base remains in the cell for 1 to 2 days, the cell
windows may need to be replaced (see
Section 5.5 ).
