1995 edition of Chinese Pharmacopoeia (1998 supplement) amoxicillin content determination, I think the sample injection concentration to be changed. Determination of amoxicillin content by high performance liquid chromatography according to the conditions provided by the supplement, the sample injection concentration of 1.2mg / ml, with this concentration determination, the absorption value and the level value (LEVEL) up to the maximum, not immediately Drop but a short stay, and the absorption value is particularly large, larger paper speed will find its peak is a straight line, the emergence of “flat peak”, rather than the normal distribution of sharp peaks, and this attenuation set
