Perkin Elmer Turbomass Error

[Fat Jonny]

Anybody ever encountered the error below before? I'm running dual detection GCMS and GCFID.

-991 Rawfile is in error state after name/reset operation. Deleting
-991 Rawfile created in backup location. New path: C:\TurboMass\TurboMass\Ver5.4.2\Temp\TCFUNC2-20080907-001256.raw

This occurs roughly every 20 samples or so, and makes the sequence jump a sample, i.e. once the run has completed, if you open the data from sample 20 you are actually looking at the results of sample 21.

This is severely screwing up my runs and has major implications for GLP runs!

Hi, it is happy to read your post, I am suffering the same problem with turbomass software, may I ask how you solve the problem?
Thank you.

Not certain, but it sounds like your data acquisition PC is not ready for an injection when one is made.
Maybe try stopping MSD data collection before re-equilibrating the system between injections? This allows more time for full transmission of data prior to another injection being made.

Hi! It helps to reboot the instrument, just turn it off and on again.

Have not seen that specific error, but please take the following into account:
- GC run time (oven program) should be at least 20 seconds longer than any acquisition function (from either MS or FID).
- End time for FID acquisition function should be at least 10 seconds apart from MS acquisition functions end times. This is set from Method editor, Instrument, Data Channels, IIRC.
- Make sure future chromatogram names don't not exist already (Sample list).
- Make sure data path is not too long. Keep file names short and avoid problematic characters (use only letters, numbers, -, _). Watch for final spaces (should't be any).
- Allow at least 0.5 min equilibration time (Method Editor, Instrument, Oven).
- If the GC is a Clarus 6x0 series, it may help to disable the Rinse before Ready. After releasing control, go to the touchscreen and click Tools, Configuration, Run and make sure the checkbox for Sample Rinse before Ready is unchecked.
- Check the number of files within all the TurboMass projects. Would it be more than 10000, do a backup, as the OS may get too slow accessing the files. Just pack old files inside a ZIP and leave it in the same hardisk; then, erase the original files and empty the Recycle bin. This issue is not related to the size of the files, but only to its number.
- Check the PC for viruses and/or any program that may be using too many resources. Do not make any Windows upgrade.

If any of the above hints helps, please let me know which one. If it doesn't help, let us all know more about your system (GC-MS model, configuration and accesories) and problem (when it started).

Best of luck,
