Interesting.
Sulphur containing molecules can latch onto stainless steel.
Phenolics may be source of the odour

Can't think of anything useful to help clean your syringe - elevated temperature or vacuum may help to increase the evaporation of the volatiles
Might be interesting to take an SPME headspace of the syringe plunger

Hi Ralph,
Thanks for the link, that was an interesting read. I have to say that the wood vinegar headspace analysis indicated high levels of phenols, which may explain the odour. I forgot to mention that my SPME of the headspace contained no acetic acid!
I have some free time today, so may take a headspace sample of the syringe plunger!
Cheers,
Joe

if it is just the metal parts that are smelling, why not simply put them in an oven at e.g; 150°C ?
Hi,
Thanks for the suggestion, I will give this a try today!
