Creating PowerLine Methods
This chapter describes how to create the time-based tables required for unattended
operation of the Waters 600E Multisolvent Delivery System. You can combine these tables
to compose a method.
A method is a set of instructions that controls how and when a run is made. In the Waters
600E system, a method comprises a set of timed-based tables consisting of:
• Gradient tables to control the 600E pump
• Event tables to control external devices
• Detector tables to control the PowerLine detectors in your system
The time-based tables of the same set are identified by the same number, which is listed in
a Method table (Figure 6-1). When the system executes that table number, the set of
gradient, event, and detector tables having that number run simultaneously.
The 600E system can store up to 15 sets of tables that allow you to:
• Run a series of samples under the same or different conditions
• Implement flow and eluent compositional gradients
• Actuate external devices
• Change wavelengths and attenuations
• Program special method functions (special vial codes)
