Purging means rinsing the system or system components for a certain time at a higher flow rate. Purging is required in various situations and for different reasons. The situation and reason determine which script is the best to use. The tables provide information for the most common situations. You start the scripts from the Vanquish User Interface. Follow the script instructions if applicable.

During Operation
Reason | Script | Additional Parameter |
---|---|---|
To replace a solvent reservoir or autosampler wash liquid reservoir when the liquid level in the reservoir is too low for the next analysis (same type of liquid) | B01 - Change Liquids / Solvents | Select the affected solvent or wash liquid and Refresh Only = On. |
One or more solvent lines or autosampler wash liquid lines have been empty | B01 - Change Liquids / Solvents | Select the affected solvent or wash liquid and Refresh Only = Off. |
To change to a different set of liquid (solvent or autosampler wash liquid), for example, when changing to a different analytical method | B01 - Change Liquids / Solvents | Select the affected solvent or wash liquid and Refresh Only = Off. |
During Maintenance
Reason | Script | Additional Parameter |
---|---|---|
Pump maintenance: At the beginning of a maintenance procedure: To flush out harmful substances At the end of a maintenance procedure: To remove air that might be trapped in the system due to the procedure | C02 - Purge Pump | What Should Be Purged = Entire Pump Intensity = Standard |
Autosampler maintenance: To remove air that might be trapped in the system due to the procedure | C04 - Purge Sampler | What Should Be Purged = Entire Sampler Intensity = Intense |
During Troubleshooting
Why | Script |
---|---|
To remove air that might be trapped in the system, for example leading to pulsation issues during operation, high noise level, or non-reproducible analysis | Depends on the potential cause. See System Troubleshooting. |
