We have an HP 6890 (G1530A) and the inlet can no longer get to the desired 240C, it lingers around 230C tops. Does anyone have a recommendation on how to fix it? I would really appreciate it!

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..
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...
Thanks! Only a 6890 for now, but looking to add a 7890 potentially in 2022!
Hi Anatoly,
Part G1530-67950 is the current heater sensor for 6890 S/SL inlet.
Regards
James
How do I find a part number for the heater, in case the sensor doesn't fix it? Or would I buy the whole inlet assembly?
Thank you very much, James! What about the heater assembly, in case the new sensor doesn't fix it?
When a product is supported for a quarter of a century like the 6890 has been, over that time some part suppliers change or slight modifications are made. Either reason can be cause for a part number to change, even though the part serves the same functionality. If an old part number has been obsoleted but a new number is stated as the replacement, then yes it is backwards compatible.
Just a FYI, if you decide to replace the thermal cable and heater yourself, the thermal block and inlet weldment may need to be ordered as well. Sometimes the inlet weldment will stick inside the thermal block, and my personal experience is the heater itself sticks in the thermal block from years of high temperatures.

Thank you so very much! We will try it one step at a time - always trying to save money here :)
