I found major deposits within my autosampler probe after doing an analysis with MP-AES which the rinse solution (high purity water) wasn't able to remove.
How do I remove these deposits within both the probe and the autosampler tubing?
Thanks!

Hi Shane,
We have a recommended regeneration procedure for the probe, usually used for ICP-MS to get rid of sticky elements that contribute to the background. Note this is an aggressive strip and clean that you can only perform about 3-times before you will need to replace the probe.
4-step rinse by pumping ~50mL of:
Aim to pump 50ml in 30-40 min each (@1.5mL/min)
As Peter mentions suggest relook at your rinse to ensure it is cleaning out your sample matrix sufficiently each time.
Hope that helps.
Rgds, Gareth

This could be work for a sample probe of Headspace Autosampler?
