Analytical conditions of gas chromatographic separation of triglycerides were described. On-column injection system using glass column was superior in higher trighycerides to the conventional sampling method. It was demonstrated that OV-17 has excellent stability up to temperature 400° comparing with other liquid phases SE-30, OV-1 and Versamid 900 by the thermal balance analysis. Reproducibility of quantitative analysis on triglycerides was studied by square method. Relative deviation of each peak area was found less than 5%. Under the beat condition, triglycerides of milk or its products can be determined using ratio index of lower to higher ones.
