Manufacturing Quality Control of Mordant Red 7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~520 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Simultaneously detects trace metal concentrations after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Determines chloride ion concentration based on potential change during silver nitrate titration using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 under controlled conditions and determines mass after ignition and weighing. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue remaining after high-temperature incineration at 700-800 C. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) using calibrated glass electrode. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents and volatile organics using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
| Bulk Density | USP <616> Method I | Measures mass per unit volume of powder poured freely into a graduated cylinder under standardized conditions. |
| Color Value (CIE Lab*) | Reflectance Spectrophotometry | Quantifies color coordinates relative to standard illuminant D65 and 10-degree observer using diffuse reflectance measurement. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects and enumerates viable aerobic microorganisms by filtration, membrane transfer to agar, and colony enumeration after incubation. |
