Manufacturing Quality Control of PATENT BLUE V
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at lambda-max (~630 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content by atomization and absorption of characteristic wavelength radiation. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after controlled high-temperature combustion and weighing of the ash. |
| Water Content | Karl Fischer Titration | Electrochemically quantifies water via iodine-sulfur dioxide reaction in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile impurities remaining after ignition at 500-600 C and subsequent weighing. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate and endpoint determination via silver electrode potential change. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a standardized 1% w/v aqueous solution using calibrated glass electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents based on retention time and flame ionization detection response. |
| Related Substances | High Performance Liquid Chromatography (HPLC-UV) | Separates and detects structurally related impurities using reversed-phase column and UV detection at 254/630 nm. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume by measuring weight of sample freely poured into a calibrated cylinder. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration after incubation. |
