Introduction
Before beginning to
work with any HPLC instrument one must
understand the basic principles of
liquid chromatography at its various
modes.
The
liquid chromatograph is very complex and
it consists of sophisticated technology
and sometimes delicate and total
ignorance in the manner it works might
sabotage its parts which are very
expensive. In addition, there are
chemical processes of distribution
between the two phases, the mobile and
stationary, while the analysis goes on,
and there is a need for a minimum
understanding of their theoretical basis
to operate the system correctly.
Also, a minimum understanding of the
method, in which the system performs
data analysis, is needed so that no
false data or results will be obtained
in the analysis.
LISTS OF STEPS NEEDED BEFORE ANY
RUN BY HPLC רשימת צעדים
מקדימים לפני הרצה :
- Filter the solvents with membranes
with cutoff of 0.22-0.45 mM
- Use clean and transparent
reservoirs through which
precipitates and colloids can be
distinguished.
- Make sure that the solvents will
be easily mixed with the previous
solvents in the same inlets (A, B,
C, D). For example methanol or
water should not be placed instead
of hexane directly, or any organic
solvent should not be placed
directly instead of a buffer
reservoir.
- Degass the solvents and purge all
the tubing that lead to the pump.
- Connect the column carefully
according to the flow direction
marked on it (do not connect
directly to the detector).
- Flow the
appropriate solvents through the
column at a low flow-rate (0.1-0.5
ml/min) or reach the composition
gradually using the appropriate
gradient.
- Select the appropriate
wavelength (or other type of
setting) in the detector and wait
for stable baseline
- Prepare the set of methods in the
workstation: Instrument method for
the control on the system,
Processing method for the data
processing and the Report method for
the report of final results.
- When the system and the methods
are ready a blank run should be
performed to test the system and
verify that it is clean from
interferences.
