Using the operator interface 3-27
Stand-alone operation
When using the detector as a stand-alone instrument, you can store up to five
methods containing up to 50 timed and 2 threshold events each. An asterisk in
the method number field on the absorbance screen indicates current
conditions, not a stored method. See
“Programming timed events, threshold
events, and methods” on page 3-35 for information on how to store a method.
Remote control
To operate under Empower or MassLynx control, the detector uses the
Ethernet bus connector (see
“Making Ethernet connections” on page 2-14 ).
To connect the detector to your HPLC system, see “Making fluid line
connections” on page 2-6 .
When under the control of an external data system, the detector is operating
under remote control conditions. The Remote Control icon, containing the
letter E, is present on the absorbance screen (see the table on
page 3-4 ).
See “Making signal connections” on page 2-11 , for more information on
connecting the detector to an external system.
Verifying the detector
After you have installed the detector, verify that it is operating properly by
performing the procedures in this section.
For complete validation procedures, you must obtain the Waters accuracy and
linearity cuvette kits and system qualification tool for the detector. See
Appendix C for part numbers and ordering information.
Tip:
Before you pump solvent or mobile phase through the system, flush the
lines with filtered, degassed, and sparged HPLC-grade methanol. Then pump
your mobile phase, provided that there are no miscibility problems, at 1
mL/min for 15 minutes minimum.
Before you begin
Because the detector is shipped dry, you must pump solvent through the unit
before initial use.
Rule:
To ensure accurate verification, be sure to start up the detector and
follow steps 1 to 3 in this section and 1 to 4 in “Recording sample and
