【Abstract】 Internal standard method is a conventional chromatographic quantitative method which requires one or several internal standards added The internal standard component must not be contained in the sample and need a good separation between the internal standard and sample components In many cases selecting an internal standard is not convenient or even restricted by the seperation of components In this paper, we try to combine the internal standard method and the addition method to form a new chromatographic quantitation method named addition internal standard method The principles of addition internal standard method are suitable to not only chromatographic quantitation but also polarography etc The related theory and foundation of the method are defined The operation steps and the conditions suitable to the method are discussed The advantages and disadvantages of this method are explained in detail更多还原
