Microreactor for methanolysis of triglycerides before gas-liquid chromatography.
A rapid, accurate microtechnique has been developed for gas chromatographic determination of the fatty acid composition of small (2-3 micro l) samples of vegetable oils. This microtechnique combines transesterification and sample injection into a single operation. The fatty acid compositions of soybean, linseed, and safflower oils thus determined are compared with those obtained by the usual two-step procedure.
