You might have significant oxidation of your samples, especially of unsaturated
fats, and
there are plenty of those in fish oil. I would put the sample in an air-tight
container,
preferably glass, and blow argon over it, or if you don't have argon, you could
use
nitrogen gas. Otherwise you could put the samples in food-grade plastic bags
which you
then vacuum-seal.
