So you did a test run and it appeared to work, then you did a regular run and all your beads went to waste again....is that correct?

I think this goes back to what "snetmcom" said, if there are beads in the waste then they must have passed through the filter at some stage. They shouldn't be able to do this so it must be the source of your problem.
There are several washes of your beads on the filter, during one wash an aliqout is taken off to the QC output (before enrichment). This should happen even if your emPCR has failed. If you're not getting anything in the QC output then it looks like your beads are passing through the filter for some reason. Probably a good idea to check your lot numbers with your rep.

Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.
The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
