Manufacturing Quality Control of Quercetin hydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies quercetin dihydrate content using reverse-phase HPLC with UV detection at 370 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities (e.g., quercetin anhydrous, isoquercitrin) via HPLC with diode-array detection and spectral comparison. |
| Water Content | Karl Fischer Titration | Determines total water content (including crystalline water) by coulometric or volumetric titration with iodine-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after controlled high-temperature incineration and weighing of residual material. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Quantifies trace heavy metal elements using inductively coupled plasma mass spectrometry for multi-element detection at sub-pptr levels. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after ignition with sulfuric acid treatment, indicating mineral impurity load. |
| Chloride | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating under controlled conditions to assess volatile content excluding crystalline water. |
| Microbial Limits | Membrane Filtration | Determines total aerobic microbial count and absence of specified pathogens (E. coli, Salmonella) using culture-based membrane filtration. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing light scattering pattern of dispersed sample in liquid medium. |
| pH of Aqueous Suspension | Potentiometric Measurement | Determines pH of a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
