Creating a Gradient Table 173
Chapter 10
Creating Gradient Controller
Time-Based Tables
This chapter describes how to create time-based tables (gradient tables and event tables)
for unattended operation of the Waters 600E Multisolvent Delivery System.
Gradient tables control the 600E pump, whereas event tables control external devices
connected to the 600 controller. Each time-based table has an identification number. When
the system executes a table number, the gradient and event tables with that number run
simultaneously.
The 600E system can store up to 15 sets of tables that allow you to:
• Run a series of samples
• Implement flow and eluent compositional gradients
• Actuate external devices
Once you create these tables, you can run them as described in Section Chapter 11,
Running Gradients.
10.1 Creating a Gradient Table
This section describes how to define and document the information you will program into
the gradient table to control the 600E pump, including:
• Documenting the gradient table
• Programming the gradient table
Note: When you create gradient and event tables, be sure that you design the
time-related changes specified in each table to work effectively with the time-related
changes in the other table of the set.
