shelf life at -86C

How long can one store pesticide extracts at -86C in anorganic solvent - say a quecher's matrix?
Hi
A bit of a wide question considering the number of different families of pesticides, can you narrow it down abit?
To stress the stability point a bit, you can instant deep freeze a substance, but in the wrong enviroment thawing will cause breakdown spoiling any validation/accurate sampling attempt. To give an example, a few years ago I worked with substances containing a dichlorinated bensaldehyde function, just picking the wrong solvent working with +99% standards spoiled the work.
