Not in the way that you're thinking I suspect!
If you are dead set on using GC, then you could potentially derivatize your compound of interest which could help address issues with its thermal stability. However this would (for me) be a last resort.
Personally I think that it might be wiser to consider derivatization only after you have satisfied yourself that changing run parameters cannot address the problem. Firstly, where do you think the decomposition is happening?
If it's the injector (which is common) then you could consider either trying to lower the injector dwell time or the temperature, or perhaps both. If you're running splitless, consider using a split flow which should lower injector dwell time, but obviously has consequences on sensitivity as you're dumping some of your sample overboard. Why not drop the injector temperature... Yes it can affect HMW components and lead to band broadening if you go too far, but at least give it a try. Is your liner dirty, or is it the type stuffed with glass wool? If so get a new liner (perhaps without glass wool), this can help minimise thermal degradation.
If its the column, it's mostly a matter of temperature programme (possibly slower ramps) and possibly thinking about whether a different column might help or not. From what I gather from people with a lot more experience than me, a thinner film thickness can help, but obviously as with all things, what you gain on the swings, you lose on the roundabouts.
Something to think about.
