– Methods specifying vial numbers
– Number of injections from each vial
– Injection volume
The controller can contain 15 sets of Method tables. Each set of tables can
contain these individual tables:
• Gradient – Includes up to 15 operational steps that define the varying
solvent composition, flow rate, time range, and rate of change for each
phase of the gradient.
• Event – Includes up to 15 operational steps to control output signals to
external devices, internal alarms, sparge rate, and linking operation to
other tables.
• Detector – Includes up to 15 operational steps to change wavelength
and attenuation during a run.
You can create a Method table, a time-based program that can include up to
48 individual steps. Each step accesses a set of Gradient/Event/Detector
tables. These are among the tasks the Method table can perform:
• Equilibrating the system for a specific period of time
• Switching solvents
• Purging the autoinjector
• Purging the 2414 RI Detector flow cell
• Performing a series of small-scale or large-scale injections
• Cleaning up following buffer use
• Lowering the system flow rate after an analysis
Having programmed the Method table, you can instruct the system to start at
any step in the process.
