Assay
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 (C
21H
39N
7O
12) 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.
