Manufacturing Quality Control of Fast Red B salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 510 nm, comparing peak area against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in pyridine-methanol buffer. |
| Ash Content | Gravimetric Analysis | Incineration at 550 C to oxidize organic matter, followed by weighing of residual inorganic ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, using air-acetylene flame AAS with lead-specific hollow cathode lamp. |
| Chloride Impurity | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential jump due to AgCl precipitation. |
| pH of 1% Aqueous Solution | pH Meter Measurement | Direct measurement of pH using calibrated glass electrode in a 1% w/v aqueous suspension at 25 C. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary GC with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed aqueous slurry. |
| Solubility in Water | Visual Inspection & Filtration | Qualitative assessment of complete dissolution in distilled water at 20 C, followed by filtration to detect insoluble residue. |
| Color Value (Absorbance) | UV-Vis Spectrophotometry | Measurement of absorbance at specified wavelength (e.g., 510 nm) in standardized solution, normalized to concentration and path length. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C until constant weight; mass loss reflects volatile content, residue indicates inorganic impurities. |
| Bulk Density | Graduated Cylinder Method | Mass of freely poured sample divided by its volumetric reading in a calibrated cylinder, measured under standardized conditions. |
