In order to protect the
separation columns against pollution Precolumn
Cartridges and Guard
Columns
are recommended.
For the realization of analyses
with modern HPLC equipments in many cases the use of Narrowbore
and Microbore Columns is of advantage.
Using a modern HPLC equipment
there is no need for conventional 4 mm columns in analytical scale. Already
the transition from a 4 mm column to a 3 mm column can save up to € 300.00 per
month for solvents ! As shown in the example below, you need not even a "special"
equipment.
Retention
times, selectivities, plate numbers, prepressures and also the life time of
small diameter columns do not alter in comparison to the corresponding 4 mm
columns !
Small diameter columns from SEPSERV
have the same quality as 4 mm columns.
With a modern analytical pump
head and an analytical flow cell working with 3 mm separation columns is
no problem.
For the use of 2 mm (Narrowbore)-
and 1 mm (Microbore)-columns usually a microcell is necessary.
Save your money and protect the
