Vanquish Diode Array Detectors (VH-D10) Operating Manual
Before Starting Sample Analysis
Before starting an analysis:
•
Check the liquid level in the solvent reservoirs. Verify that the
amount of solvent is sufficient for the analysis.
•
Verify that the doors of the modules in the Vanquish system are
closed.
•
Observe the guidelines for use of LightPipe flow cells in
NOTICE
LightPipe flow cells are highly sensitive. Make sure that you
have read and follow all safety notes and guidelines for LightPipe
flow cells.
•
Make sure that the chromatography system is properly equilibrated.
System equilibration should include the following operations:
♦
Purging the pump (
all
channels, including those not used for the
application)
♦
Flushing the entire chromatography system with the starting
solvent to rinse out any solvent from a previous analysis run
♦
Warming up (or cooling down) all temperature-controlled
devices in the system to the starting temperature
Temperature-controlled devices can be, for example,
♦
Column compartment and post-column cooler
♦
Sample compartment thermostatting in the autosampler
♦
Flow cell in a fluorescence detector
♦
Evaporation tube in a charged aerosol detector
♦
Turning on the lamp (or lamps) in the UV/VIS detector
♦
Monitoring the pump pressure and pressure ripple and checking
that the pressure is stable and the ripple within reasonable
limits for the application
♦
Monitoring the detector signal and checking whether the
detector signal is stable so that the drift and signal noise are
within reasonable limits for the application
♦
Performing an autozero of the detector baseline
