Solvent Filtration
Column inlet frit contamination can increase column back pressure and reduce efficiency.
Microbore column blockages are a particular problem, due to the small diameter of the inlet
frit. To prevent blockages, always use the appropriate filters in your LC system. Agilent offers
two types of high pressure in-line filter kits for use with any HPLC system.
Universal Solvent Filter
Ideal for microbore, narrow-bore, high-speed
or standard analytical columns.
Universal solvent filters are installed between the LC pump and the injector, so particles from
the solvent can be removed before they reach the injector. The filter assembly consists of a
4.8 mm frit, two inserts and a two-piece holder. The frit is placed between the tapered edges
of the inserts in such a way that the solvent is evenly distributed over the whole surface
of the frit. This provides efficient filtration and extends the life of the frit.
Low-volume Column Inlet Filter
A high-capacity filter with built-in efficiency.
This low-volume column inlet filter is positioned immediately before the LC column, so it can
remove particles from both the injection system and the sample. With a frit diameter of only
2.1 mm – plus tapered inserts – this filter minimizes external bandspreading while maximizing
the filtration capacity.
In Line Filters
Low dispersion in-line filter Universal in-line filter
Positioned immediately before
the LC column
Removes particles from the sample
and injection system
Minimizes external band spreading due
to frit diameter of only 2.1 mm
and tapered inserts
Can be used with any microbore, high
speed, or standard analytical columns
Installed between the LC pump and the
injector to remove particles from the solvent
Uses a high capacity filter
Frit is placed between the tapered edges
of the inserts so the solvent is evenly
distributed over the filtering frit
