Precolumns (guard columns)
Precolumns are available in 2 cm and 5 cm lengths, and can be filled with either
5µ packing or 37 - 44µ pellicular packing. Both lengths are used in conjunction
with a column end fitting. When packed for high efficiency they can be used as
analytical columns, but a more typical use is as a guard column installed between
the injector and the analytical column. Standard material is Type 316 stainless.

Fingertight HPLC cartridge precolumns
This cartridge-based system is designed for use as a precolumn or concentrator
column in HPLC and FIA applications. It is particularly suited to applications
requiring frequent changes: snap-on seals are replaceable, the cartridge is
reusable, and the tubing connections are stable since the end fittings do not
rotate as the assembly is tightened. Standard material is Type 316 stainless, with
PEEK seals and 2µ titanium frits.
