• End-line filter is dirty or clogged
When new, end-line filters (P/N 045987) are pure white. If the system is in
continuous operation, change the end-line filter weekly, or whenever it
becomes discolored. Replace the filter more often if bacterial buildup is
visible or if the eluent does not contain solvent. See the Pressurizable
Reservoir Installation Instructions for more information about end-line filters.
NOTE It is especially important to regularly replace end-line
filters when using aqueous eluents, which may
contaminate the filter with bacteria or algae. The
bacterial buildup may not be visible.
