Manufacturing Quality Control of CARBOL FUCHSIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~540 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 550-600 C and weighing residual mass after complete combustion of organic matter. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace; quantifies total heavy metals after acid digestion and chelation. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects endpoint via silver-silver chloride electrode during titration with standardized silver nitrate solution. |
| Sulfate Impurity | Gravimetric Analysis (BaSO4 precipitation) | Precipitates sulfate as barium sulfate under controlled pH and temperature, then weighs dried precipitate. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode and reference electrode in a 1% w/v aqueous solution. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube and calibrated thermometer or digital melting point system. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic impurities using capillary column and flame ionization detection against internal/external standards. |
| Color (APHA) | Visual Comparison or Photometric Colorimeter | Compares sample color intensity in solution to APHA platinum-cobalt standard scale under controlled lighting conditions. |
| Solubility in Water | Qualitative Gravimetric Test | Evaluates complete dissolution of specified mass in defined volume of distilled water at 25 C with visual inspection after agitation and settling. |
| Specific Absorbance (A(1%,1cm)) | UV-Vis Spectrophotometry | Calculates absorbance per 1% w/v concentration in 1 cm pathlength cell at specified wavelength, verifying spectral purity and batch consistency. |
