| TESTS | SPECIFICATIONS |
| Appearance | White to off-white crystalline powder |
| Identification | A: Infrared absorption |
| B: The R, value of the principal spot in the thin-layer chromatogram of the test solution as obtained in the test for chromatographic purity corresponds to that obtained from standard solution A | |
| C: Dissolve about 1g in 15ml of ammonium hydroxide and 15ml of water in a 50ml volumetric flask, dilute with water to volume, and mix: the solution so obtained responds to the tests for Silver | |
| Loss on drying | ≤0.5% |
| Limit of nitrate | ≤0.1% |
| Chromatographic purity | No secondary spot in the chromatogram of the test solution is greater or more intense than the principal spot obtained from standard solution B(1.0%) |
| The sum of all secondary spots observed is not greater than 2.0% | |
| Silver content | 29.3~30.5% |
| Assay | 98.0~102.0% |
| Particle size | The average particle size is not greater than 10μm and the size of not more than 10% of the particles is grater than 40μ |
