|
|
異溴粉霧劑,BP藥典標準中,有關(guān)物質(zhì)項下,同時收載了薄層和液相兩種方法,限度分別是: A. Carry out the method for thin-layer chromatography: LIMITS In the chromatogram obtained with solution (1): any spot corresponding to tropic acid is not more intense than the spot in the chromatogram obtained with solution (2)(0.5%); any other secondary spot is not more intense than the spot in the chromatogram obtained with solution (2)(0.5%). B. Carry out the method for liquid chromatography: LIMITS In the chromatogram obtained with solution (1): the area of any secondary peak is not greater than the area of the principal peak in the chromatogram obtained with solution (2) (0.5%); the sum of the areas of any such peaks is not greater than twice the area of the principal peak in the chromatogram obtained with solution (2) (1%). Disregard any peak with an area less than 0.1 times the area of the principal peak in the chromatogram obtained with solution (2) (0.05%). 請問,兩種方法需要同時滿足嗎?還是選擇其中的一種即可? |
