| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical form of the sample. Qualified chloramine B should be a white or off-white crystalline powder with no visible impurities. |
| Identification | Chemical Color Reaction / UV Spectroscopy | Identify chloramine B by its characteristic absorption peak at a specific wavelength (e.g., approximately 220 nm) using UV spectroscopy; alternatively, perform chemical identification by reacting with potassium iodide to release iodine, producing a blue color with starch. |
| Assay | Iodometric Titration (Redox Titration) | Under acidic conditions, chloramine B oxidizes potassium iodide to release iodine, which is then titrated with a standardized sodium thiosulfate solution. The content of active chlorine is calculated and used to determine the chloramine B content. |
| Water Content | Karl Fischer Method | Quantitatively determine the moisture content in the sample using Karl Fischer reagent; suitable for trace moisture analysis with high accuracy. |
| pH Value | pH Meter Method | Prepare a defined aqueous solution of chloramine B (e.g., 1%) and measure its pH using a calibrated pH meter; the pH should generally fall within the range of 5.0 to 7.0. |
| Heavy Metals | Sulfide Colorimetric Method (e.g., Lead Limit) | After sample treatment, react under weakly acidic conditions with hydrogen sulfide or sodium sulfide to form colored sulfides; compare with standard reference series to ensure heavy metal content (e.g., Pb) does not exceed specified limits. |
| Residue on Ignition | Residue on Ignition Method | Ignite the sample at high temperature and weigh the residual non-volatile inorganic matter to evaluate the level of inorganic impurities. |
| Microbial Limits | Microbial Limit Test | Perform microbial limit testing according to the Chinese Pharmacopoeia or relevant standards, including aerobic bacterial count, mold and yeast counts, and tests for specified control microorganisms (e.g., Escherichia coli), to ensure compliance with microbial limits for non-sterile pharmaceutical products. |
