Manufacturing Quality Control of Brilliant Cresyl Blue
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~590 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter against established visual standards. |
| Solubility in Water | Gravimetric Dissolution Test | Determines complete dissolution behavior in distilled water at specified temperature and agitation time; pass/fail based on clarity. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measures mass loss upon heating to 105 C for 2 h, indicating volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after controlled ignition at 600 C in presence of sulfuric acid. |
| Heavy Metals (as Pb) | ICP-OES | Simultaneously quantifies trace heavy metals (Pb, Cd, Hg, As, Cr) by plasma excitation and elemental emission intensity measurement. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Uses silver nitrate titrant and silver indicator electrode to detect endpoint via potential change due to AgCl precipitation. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 in acidic medium; dried and weighed to determine sulfate content. |
| pH of 1% Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated pH meter with glass electrode in standardized aqueous suspension. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase column and UV detection at 254/590 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference standard. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized cylinder and balance. |
