HP 6890 inlet heater failing

Hi Anatoly,

Logically, this is a service call to check onsite and to get support from local agilent.

But if you want to do by yourself then check heater of inlet block.

May be it's malfunctioning or going to damage.

If you have two same inlet in GC then by swapping, you can confirm it...

Even sensor also may corrupt..

Thanks!  I can't find an inlet, so we'll try the sensor first.  I've looked at Full Spectrum online store, is there another source of obsolete Agilent parts out there?  I assume the 6890 is obsolete?

Share type of inlet like split/splitless or coc or methanizer or ptv?

It's a split/splitless

The 6890 is obsolete from a sell as new perspective, and it has passed its guaranteed support stage, however it is still on "best effort" support which means Agilent can repair it while we still have the parts.  Agilent still has 6890 parts.

A service call could be placed with Agilent.

If you have part # then you can order from agilent.

Still 6890 parts showing in agilent parts order category..

The original part seems to have been obsoleted twice.  The new part number is here: https://www.agilent.com/store/en_US/Prod-G1530-67950/G1530-67950  Now I have a dilemma, to buy a new part or refurbished from Full Spectrum...

I am particularly concerned with the part number having changed twice.  Is there a guarantee that this new part number is fully backwards compatible?

In above link, it's showing part # changed two times and finally G1530-67950 which is used in 7890 also..

so if you have any 7890 then can check and confirm the root cause.

Or log a service call from Agilent...
