Missing Vial Error Message

[sharma]

Dear All,

While running a sequence on Waters Alliance HPLC, the system gave the message 'Missing Vial' and stopped. When we checked the carousal, the vial was placed there.

Have anyone experienced the same?

Regards

Not with this particular hardware, but every instrument that I have ever worked with has occasionally suffered a glitch with no apparent cause, and no cure, in that the instrument then went on to work perfectly again.

It is a rule of troubleshooting that a problem that only occurs once is not a problem.

Was it a "normal" vial, or a total recovery?
We had this problem in the past with total recovery (or maximum recovery, I'm not sure).
Adjusting the vial sensor has lowered the occurence of the problem, but doesn't really eliminate.
We then switched to inserts, and never had the problem.
In case it's a normal vial, maybe the vial sensor has been moved out of position (maybe when changing the injector frit or so?)

Thanks for your reply dear aceto_81 and Peter Apps.

I have observed this most probably for the first time.

I hope that it is for the last time - then you do not have a problem
