Error - possible auotsampler issue?

[redpanda]

I was running a series of 20 vials and the GC got to sample 12 and stopped. The needle was still in the sample vial, but it never injected. The GC displays "external device not ready at runtime"

Does anyone have a clue as to why this would stop in the middle of a run? and what to do about fixing this?

Here is the error and system:

-310,"((AIH)): Timeout waiting for APG RCI ready.", 5201, "((AIH)): Timeout reading APG controller interrupt cause at runtime"

Agilent GC-MSD: 7693 autosampler , with 7890A GC, and 5975C MSD.

Thanks.

Check that you GC runtime and sample equilibration time do not lead to the autosampler trying to inject at the same time as it should be loading a sample.

There might also be a simple malfunction in the GC that stopped it being ready. Is this kind of stoppage a regualr event ?

First thing to do in fixing things would be to power down the GC and unplug the autosampler and tray, and close the software. Then plug the tray and autosampler back in and power up the GC and reboot the computer and restart the software. Then see if the autosampler works through its startup routine of moving the needle, turret and tray arm. If it does that and looks good then try another injection.

Oh you will probably also want to manually lift the needle out of the vial before doing this just in case.

Hi all,

I'm working with a TD-GC-MS system.. Agilent 7820A + 5975c + Unity 2 Thermal desorption Unit. In fact this last component acts as a injector device for the GC. After using successfully the system for several months, now in the Chemstation appears a similar error than the initially posted. In fact it does not allow me to proceed with my runs.

-310, "({AHI} ): 5201 Timeout waiting for APG RCI ready" 5201, "({AIH} ): Timeout reading APG. Controller interrupt cause".

Evidently in this case I don´t use an autosampler and the injection is replaced by the rapid desorption of my analytes directly into the column. The TD software is somehow link to the chemstation so once the desorption is done, the method can start running. Even when the timer starts, the MSD never does nothing. the filament keeps turned off and consequently there is no data acquisition.

Have you ever deal with this kind of problem? any suggestion would be very helpful.....

Thanks,

Oscar

The thermal desorber IS an autosampler.

Glitches like this are just part of life when you try to get the softwares from different systems to talk to one another. Some combinations are worse than others, one problem in several months is annoying but not life threatening.

Close down, re-start and see what happens.

Yes, you are right.... After some attempts of re-starting the GC, PC, etc... I decided to reboot the controller of the MSD (directly from the menu of the front panel of the MSD). Doing this the system has worked again. I lost some time but that's the work....

Thanks......
