Hello:
If I understand your meaning of "dirty power" to include 'brown outs,
power fluctuations and spikes' then... yes we have observed some bizarre
behavior on our flow cytometer. These include a partical head crash
during acquisition, corrupted cross-linked data files. These files were
lost for forever!!! It also caused the cytometer to behave weird. I
beleive we used a Norton Disk Doctor type product to locate and clear-out
the corrupted and cross-linked files followed by a Speedisk to
reconfigure the hard drive. Without a dedicated power protection system
to the flow cytometer these bizarre events will continue to occur. I
would suggest you contact your local Flow Cytometry Rep and Computer
Specialist for what ever company your cytometer was bought. I hope this
has helped.
