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"
times, selectivities, plate numbers, prepressures and also the life time of
small diameter columns do not alter in comparison to the corresponding 4 mm
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
For the use of 2 mm (Narrowbore)-
and 1 mm (Microbore)-columns usually a microcell is necessary.
