Summary Thin layer chromatography, gas liquid chromatography and colorimetric procedures were used to identify and determine amines present in standard solutions, cod muscle extracts, and in the toluene phase of a modified TMA procedure. These tests show that the use of potassium hydroxide solution to liberate TMA from formalized trichloracetic acid extracts of fresh or frozen cod is superior to potassium carbonate solution.
