Although it's volatile, it's not very very volatile, so if you pump too much in, it will start to block things, like the aperture at the front of the mass spec (ion transfer capillary or whatever it's called in your instrument). I don't know if it will also contaminate ion optics.
My inclination with your instrument in its current state would be to see if it still works, and if it does, breathe a sigh of relief and go back to normal concentrations. If there is a check-tune option, it might be worth doing it, as that's a quick way to check that it's a happy instrument. Alternatively just run a known standard and make sure the spectral quality is as good as normal, the peak the right size, etc.
good luck!
