1. A method of analyzing a sample comprising a fatty acid of interest, the method comprising:
preparing an aqueous solution comprising fatty acid of interest, wherein a concentration of the fatty acid of interest is less than about 1 μM;
placing the solution in contact with a surface of a polypropylene substrate, wherein the surface has been treated to reduce adsorption of the fatty acid of interest as compared to a non-treated surface; and
analyzing the sample using mass spectrometry with respect to the fatty acid of interest.
