How can I identify and neutralize the chemical leaching out of new nitrile gloves? I have a few cases of brand-new, nitrile gloves of a type and vendor that used to be good.  But apparently, the vendor has moved manufacturing to a different country and outsourced customer service to Hell. I can't return the gloves.

The gloves all have a chemical smell, resembling a burnt transistor with a hint of burnt rubber. If worn for a while, they irritate the skin.  

Since this model of glove used to be outstanding, and the cases were not cheap, I'm hoping there's some way to salvage the gloves.  I've tried repeated washings in mild detergent, or just airing them out for 4 weeks. No change.

What chemical(s) is/are this likely to be?  How can I tell?
Is there a way to neutralize this/these compound(s) without otherwise destroying the gloves?
Pack a glove into a glass container, let it sit for a few hours or days, get the container to your institute's mass spectroscopy and gas chromatography departments, and have them have a go at the gas phase in the container. I think that might be your best bet at finding out what is leaking out of these gloves. An IR or UV/Vis of the gas phase might also yield results, as Spießbürger suggested above. 

Actually, if you got an analytics department at your university/institute, why not go to them, they might be able to have someone do a B.Sc. or M.Sc. thesis on that. Even if you end up trashing the gloves, at least then it won't have been a complete waste.
