Chromatography Forum

Hi felows. There is a situation occuring with the HPLC in the lab. During an analysis, suddenly appears the following messages.

It is ilegal call while it is in the message filter.

Virtual instruments application - the virtual instrument application has
found a problem and needs to be closed.

Run time erro
Program C /class VP/int.exe abnormal program termination

And the chromatogram stops appearing in the screen.
It has not been possible to performe more than 10 analysis, because it
always happens. Has anyone dealed with this before:

You might get more answers if you told us some details:
- what model of instrument (presumably Shimadzu)?
- what version of the software?
- what operating system?
- is this a new system, or has it been in service for some time?
- when did the problem begin?

It is Shimadzu model 10 AVP .
The software version is a Class VP 5.05
The system operating is Windows XP
It is not a new system. It has been operating for some months, but suddenly these problems have began and it has been occuring for about 2 months.
Have you ever seen it before?

<Not a Vp software user, but it sounds like it is either a memory or a space (on the hard drive) issue.

Are you collecting DAD data or very high frequency UV on multiple wavelengths?

Have you alerted your local Shimadzu associates?

I am collecting datas from a UV detector on 210 nm wavelengh only.
I have already notified Shimadzu representatives and I am waiting an answer.

The answer will have to come from Shimadzu. What happened is that the program "crashed". It could be due to almost anything: a subsequently installed program, a Windows update, or even a virus. In the "worst-case" scenario, you may have to reinstall the Class-VP program or even do a complete re-install of Windows.
