We are using the 6410 LC triple quad with 1100 series.
When we start a worklist containing multiple samples (without needle wash), the analysis works well without error.
But the issue arises when we use the "injection with needle wash" option.
When we starts the worklist, the autosampler arm grabs the sample and places the sample vial below the injection needle and the sample is well drawn.
Then, the autosampler arm grabs the washing vial, but the error occurs: the autosampler arm drops the washing vial and the worklist is stopped.
The same problem occurs when we place the washing vials in different locations.
Could you please advise us on how to resolve this problem?
Thank you for your help.
