Hello,

I'm wondering if anyone else has used methoxamine hydrochloride in pyridine as a derivitization agent for GC-MS, and knows relatively how long it can be used before it needs to be remade. I have been unable to find anything on the rest of the internet. I know that I could do another experiment to see how long it lasts before the data starts looking funny, but I was hoping that someone might be able to save me a whole lot of time if they have already something similar.

If it helps, the concentration I am using it at is 10mg/mL.

Thanks!
