[求助] 异溴粉雾剂,BP药典标准中有关物质的限度问题

异溴粉雾剂,BP药典标准中,有关物质项下,同时收载了薄层和液相两种方法,限度分别是:
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%).

请问,两种方法需要同时满足吗?还是选择其中的一种即可?
