Instrument Type:

Pump (P580 only)

Related Commands:

Learn

Description:

Compressibility always varies with different solvents. The better the pump is set to the compressibility of the respective solvent the lower is the pump's pulsation. Chromeleon allows you to determine optimum pre-compression control for the Dionex P580 pumps, using the Learn and Freeze commands.

The Freeze command completes the learn mode for determining the compressibility of the respective solvent component. (For more information, refer to Practical Tips for Device Control  Setting Automatic Pre-Compression Control (P580))

Function:

If the Freeze command is issued, the measured compressibility is saved and used for pre-compression, according to the portion of the respective component in the total flow.
