Analysis Samples: Standard solution and Sample solutionCalculate the percentage of C16H19N3O5S in the Amoxicillin and Clavulanate Potassium for Oral Suspension taken:

Result = (rU/rS) × (CS/CU) × P × F × 100

rU	=	= peak response of amoxicillin from the Sample solution
rS	=	= peak response of amoxicillin from the Standard solution
CS	=	= concentration of USP Amoxicillin RS in the Standard solution (mg/mL)
CU	=	= nominal concentration of amoxicillin in the Sample solution (mg/mL)
P	=	= potency of amoxicillin in USP Amoxicillin RS (µg/mg)
F	=	= conversion factor, 0.001 mg/µg

标准品的P值是权威部门对标准品检验出来，并且标识在标准品标签上。
