Manufacturing Quality Control of Pyrroloquinoline quinone disodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PQQ Na content) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength (330 nm) using molar absorptivity of PQQ anion. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Mass loss measured after drying at 105 C under controlled conditions to determine volatile content. |
| Residue on Ignition | Weight Loss on Ignition | Residue mass after high-temperature ashing (550-600 C) reflects inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification via plasma ionization and mass spectrometric detection with low detection limits. |
| Sodium Content | Flame Photometry | Measurement of sodium-specific emission intensity in flame for quantitative determination. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration using silver nitrate and silver electrode to detect endpoint via potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation as BaSO4 followed by filtration and weighing of dried precipitate. |
| pH (1% aqueous solution) | pH Potentiometry | Measurement using calibrated pH electrode in standardized aqueous solution. |
| Related Substances (impurity profiling) | HPLC-UV | Separation on reversed-phase column with UV detection at 254/330 nm to identify and quantify structurally related compounds. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to quantify water based on stoichiometric reaction. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic mesophilic microorganisms after filtration and culture on appropriate agar media. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern to determine volume-based particle size distribution. |
