Mobile phase, Standard preparation, System suitability solution, and Chromatographic system Proceed as directed in the Assay under Streptomycin Sulfate.
Assay preparation Transfer an accurately measured volume of Injection, equivalent to about 500 mg of streptomycin, to a 500-mL volumetric flask, dilute with water to volume, and mix. Transfer 5.0 mL of this solution to a 200-mL volumetric flask, dilute with water to volume, and mix.
Procedure Proceed as directed in the Assay under Streptomycin Sulfate. Calculate the quantity, in mg, of streptomycin (C21H39N7O12) in each mL of the Injection taken by the formula:
20(CP/V)(rU / rS)in which V is the volume, in mL, of Injection taken to prepare the Assay preparation; and the other terms are as defined therein.
