The results obtained in the validation of an analytic method by chromatography liquid of high resolution are presented, for the decision of vitamin B1, in milk UHT enriched and sweetened, which was designed to separate the thiamine, with the utilization of a column RP-18 of 150 x 4.6 mm and a detector UV- Visible. Said method was employed for the control of the quality of this product. The validation of an analytic method includes the evaluation of a series of parameters. They are: selectivity, linearity, precision, accuracy. We compilated all the bibliographic information we need to do the first exploratory analyses which define the final chromatographic conditions. Then, when the conditions were defined, we started the analyses for the evaluation of validation’s parameters. It was shown by the experimental design and the statistic procedures, that the proposed analytical technique is linear because the correlation coefficient obtained was r2= 0.9998; it is accurate, it was obtained a recuperation percentage of 100.07%; is precise since for the repeatability obtained was RSD of 0.446% and for the intermediate precision it is shown that do not exist differences among the variances of the analysts, finally is selective because there is no evidence of interferential chromatographic peaks. The proposed technique accomplished all established validation’s parameters established in the official papers. Thus, the validate method is reliable and it can be used in the routine analyses.
