Manufacturing Quality Control of METHYL PURPLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., 580 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Loss on Drying | Gravimetric Analysis | Determines volatile content by measuring mass loss after drying at specified temperature (e.g., 105 C) under controlled conditions. |
| Water Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace; quantifies metal impurities after acid digestion. |
| Sulfate (as SO4) | Gravimetric Analysis | Precipitates sulfate as BaSO4 under acidic conditions and determines content from dried precipitate mass. |
| Chloride (as Cl) | Argentometric Titration | Titrates chloride with standardized silver nitrate solution using potentiometric or chromate indicator endpoint detection. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in a defined aqueous suspension or solution. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue remaining after high-temperature (e.g., 600 C) ashing. |
| Organic Impurities | High Performance Liquid Chromatography (HPLC) | Separates and quantifies related compounds using reversed-phase column and UV detection; compares retention times and peak areas to standards. |
| Melting Point | Capillary Melting Point Determination | Observes temperature range over which solid transitions to liquid using calibrated apparatus and standard reference materials. |
| Bulk Density | Volumetric Gravimetry | Calculates mass per unit volume of freely settled powder in a standardized cylinder. |
| Particle Size Distribution | Laser Diffraction | Measures angular scattering pattern of laser beam passed through dispersed sample to derive size distribution by Mie theory. |
