3.3. Sample analysis
Validated method was used for analysis of fatty acid profile in
different samples. Routine analysis of vegetable oils can also be
very demanding due to large differences in the content of various
fatty acids in oils of different origin. The main problem is peak
overlapping caused by peaks of major constituents: oleic acid in
e.g. olive oil and rape seed oil, linoleic acid in e.g. sunflower oil
and soya-bean oil or linolenic acid in flaxseed oil and hempseed
oil. That was the main reason for not using a faster carrier gas flow
