Hi,

I operate a PerkinElmer Clarus GC and Turbomatrix headspace sampler for Transformer Oil Dissolved Gas Analysis.

I have noted a 'vial jam in sample oven' error on the Turbomatrix unit, this appears to be because the sample oven vial compartments are not alligned to the vial entrance hole and when the vial is pushed into position it registers as a blockage.

This has happened before and the service engineer physically manipulated the vial sample oven into the correct position which I attempted, this allowed the vial to be taken into the sample oven, however it then seemed to misallign and when the needle was lowered I recieved a 'needle jam error' and possible damage to the needle.

Has anyone seen a similar issue and is there a simple fix or repair that can be carried out?

Have you tried putting it in service mode and aligning the carousel? Have your service guy show you the procedure if they didn't do so during installation. For the thermal desorber it is a fairly easy process, it self aligns as long as you insert the tube in the right place at the right time. The headspace unit should be similar.

Managed to speak to a PerkinElmer service engineer who talked me through the process of getting to the service screen on the sampler to reallign the sample oven.

Frustrated that this wasnt shown during installation and that damage may have occured to the needle. But will know the process for what I expect will be future errors.
