Manufacturing Quality Control of L-Ascorbic acid phosphate magnesium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (VC Phosphate Magnesium Content) | HPLC-UV | Quantification based on retention time and UV absorbance at 265 nm using a C18 column and phosphate-buffered mobile phase. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element detection via plasma ionization and mass spectrometric quantification with isotope dilution for trace-level accuracy. |
| Magnesium Content | Complexometric Titration with EDTA | Selective chelation of Mg2+ by EDTA at pH 10, using Eriochrome Black T indicator for endpoint detection. |
| Phosphate Content | UV-Vis Spectrophotometry (Molybdenum Blue Method) | Reduction of phosphomolybdate complex to molybdenum blue, measured at 880 nm for quantitative phosphate determination. |
| Residual Solvents (e.g., Acetone, Ethanol, Water) | GC-FID | Separation and flame ionization detection of volatile solvents using a polar capillary column and internal standard calibration. |
| Loss on Drying (LOD) | Gravimetric Method (105 C, 2 h) | Mass loss after controlled heating under standard conditions to determine volatile and moisture content. |
| pH of 1% Aqueous Suspension | Potentiometric Measurement | Direct pH measurement using calibrated glass electrode in a standardized suspension prepared per USP <791>. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution (D10, D50, D90). |
| Microbial Contamination (Total Aerobic Count) | Membrane Filtration and Plate Count | Filtration of sample solution followed by incubation on soybean-casein digest agar and colony enumeration. |
| Related Substances (Impurities) | HPLC-DAD | Separation on C18 column with gradient elution; detection and identification of impurities via UV spectra and retention time matching. |
| Chloride Impurity | Ion Chromatography (IC) | Anion exchange separation with suppressed conductivity detection for quantitative chloride determination. |
| Sulfate Impurity | Turbidimetric Method | Precipitation of sulfate as BaSO4 in acidic medium; quantification via turbidity measurement at 420 nm. |
