It might be an alignment issue. We had an alignment problem with our Sample
Case when we moved from Solid-State to liquids. There is a dummy load in the
sample case tools. You might talk to Center about how to do this process.

Hi Jessica,
I have a few thoughts about your samplecase issues.
For issue 1 - The three attempts to insert the sample is standard behavior
and usually happens when the spinner gets stuck at the interface between the
shuttle that transports the sample and the top of the shim system. If you're
lucky, it might just be one (or a few) spinner that's having problems. In that
case it's an easy fix and you just take that spinner out of service. If it's
not the spinner, then frequently the sample changer has drifted out of alignment
with the top of the shim system. In that case you have to re-align it, but that's
not trivial and if you don't get it right, it can degrade the performance of the
sample changer further. I would start by pulling problematic spinners out of
service and see if that helps things.
For issue 2 - I've seen this one time and it was with a user who was using Jae-Young
tubes with dark colored valves on top. The sample would rise up into the sample
transport and the valve of the tube would be detected by the sample changer instead
of the spinner. So the system closed the latch that holds the sample up before the
spinner was in position. When it turned the air off, the sample dropped back into
the sample holder. I'd check to see if something is tripping the sensor that detects
the spinner in the top of the sample transporter prematurely.
Hope this makes sense.
Cheers,
Mike
