Controlling the ELSD During an Injection

Controlling the ELSD During an Injection

The ELS Detector can change operational parameters in real time, during a
sample injection, using an onboard timetable.

Real-Time Operation

The ELS Detector can store in memory a series of time-based events, within a
single timetable. This timetable allows the operational settings of the ELSD to be
changed in real time during a run.
The evaporator temperature (G7102A with cooled option), gas flow, PMT gain
(G4260B), and smoothing parameters can all be configured within this timetable
to change during a sample injection.
The timetable can be used to program the gas flow, to compensate for the
change in ELSD response across a solvent gradient.
The single timetable, stored onboard the ELSD, is only customizable using the
ELSD Dimension software, which can be purchased from Agilent (ELSD
Dimension Software (includes trigger cable) (PL0890-0375)). A trigger cable has
to be ordered separately. Use Infinity II Trigger Cable for Dimension Software
(G4260-63002) for an Infinity II system, and Remote start cable (PL0890-0350)
for a third-party system.

Creating a Real-Time Program

To create or modify the onboard timetable, the ELSD Dimension software must
be installed on your PC.
The ELSD Dimension software package allows you to create a timetable on a PC,
which can then be downloaded to the ELSD for later use.
The ELSD Dimension software also allows you to clear a time table from the
ELSD detector memory.
The ELSD can only store a single timetable in memory, so the ELSD Dimension
software can be used to create and save multiple timetables that can be
downloaded individually later.
For further information on how to use ELSD Dimension software, please see the
ELSD Dimension software online help.
The Agilent ELSD Dimension software can only communicate with the ELSD
NOTE
using the serial port. LAN communication is not supported in ELSD Dimension.
