Vapor duct stuck in old Buchi

Greetings. I am aware that in order to remove a vapor duct, one needs to hold the lock button and simultaneously turn the combi clip and pull the duct out.

However, I have some very old spare parts, and the duct is completely stuck in crusty residue. Any advice on how to loosen this?

I have attempted hexanes and DCM to try dissolve the residue but to no avail.

Thermo XSeries II ICP-MS: embedded computer fails to start supervise (8)

We’re trying to bring an old Thermo Scientific XSeries II ICP-MS back to life and are stuck with what looks like an embedded computer/QNX issue.

The Windows PC is running PlasmaLab 2.6.2.337, while the embedded computer appears to have XSERIES Supervisor 2.5.10.

During boot, the embedded computer detects its SanDisk SDCFH-00 Rev DH X CompactFlash storage, performs a filesystem check, but then fails with:
Unable to start "supervise" (8)

We checked supervise.dat and it appears to be a 32-bit x86 ELF executable for QNX.

There is also a Thermo updater on the Windows PC that transfers files to the embedded computer through COM2, but it doesn’t seem to report which Supervisor version is currently installed.

Originally we suspected a PlasmaLab/Supervisor version mismatch, but since the embedded computer itself cannot start supervise, I’m now thinking the issue could instead be corrupted files, a failing CompactFlash card, missing dependencies/configuration, or another embedded-system problem.

Our current plan is to remove the CompactFlash card, make a complete image of it first, keep the original untouched, and inspect/work from a clone.

Has anyone worked with an XSeries II, PlasmaLab, or XSERIES Supervisor before?

Also, does anyone know exactly what QNX error (8) means when starting an executable?

Would you investigate the CompactFlash/embedded system first, or is there still a realistic chance that updating/matching PlasmaLab on the external PC could solve this?

Any old service manuals, recovery software, Supervisor files, or experience with these systems would be extremely helpful.

I can also provide photos of the boot sequence, embedded computer, CompactFlash card, updater, and exact error screens.
