| Abstract: | A method for determination of glutamic acid in sauce by LPIC is reported.Glutamic acid was separated on a seperation column before determination.The mobile phase used was 1.0mmol/L HNO3 at the flow rate of 1.0ml/min.Glutamic acid in fraction that eluted from the column were determinated by condutivity detector.Detection limit was 0.73μg/ml and precision was 0.85%.Determination on a variety of sauce was completed and fine results was obtained. |
