Columns
Technical Overview
Introduction
Agilent narrow bore GPC columns offer high performance, excellent solvent
compatibility and mechanical stability. These columns can be used with
conventional GPC equipment and provide high performance, comparable to our
conventional ID columns, the benefi t of ~ 70% reduction in solvent consumption,
increased operator safety and reduced solvent disposal costs.
To maintain the same linear velocity
through the column, the volumetric fl ow
rate must be reduced to 0.3 mL/min,
in line with the column cross sectional
Sample loadings are scaled down in
line with the reduced column volume,
and system dead volume minimized to
avoid excessive band broadening.
area. This provides signifi cantly lower
solvent consumption.
Column: 3 x PLgel 5 μm MIXED-D, 300 x 7.5 mm
(part number PL1110-6504)
