Troubleshooting and Correcting Dripping from an Autosampler Probe

To prevent dripping from an autosampler probe, ensure it is clean and free of contamination. Dripping often occurs due to contamination from handling, samples, or rinse solution. Clean the probe with 10% nitric acid, rinse with deionized water, and use chromatography-grade solvents. Clean the rinse station similarly and replace all tubing. Wear gloves to prevent recontamination and avoid using detergents. If dripping persists, check for other causes like incompatible materials or damaged probes.

A software feature called Standard Rack Avoidance has also been implemented in later versions of the 280/560 plugin to minimize this phenomenon.When this feature is enabled, the probe will travel in the X direction using the space between the sample and standard rack locations instead of for example traveling directly over the standard rack. This feature can be immplemented as follows:

1) Open Configurator

2) Right-click on the ASX-280 or ASX-560 plugin and click Edit settings
