Manufacturing Quality Control of BETA-D-LACTOSE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Beta-Lactose Content) | HPLC with Refractive Index Detection | Separation and quantification based on retention time and RI response relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in pyridine-methanol solvent. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral beta-lactose molecules in solution. |
| pH (10% w/v aqueous solution) | Potentiometric pH Measurement | Determination using calibrated glass electrode in standardized aqueous solution at 25 C. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Heating sample to 600-800 C and weighing residual inorganic ash after volatile components are removed. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and atomization, based on absorption of characteristic wavelength light. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by weighing of non-volatile sulfate residue. |
| Chloride | Potentiometric Titration with Silver Nitrate | Titration using AgNO3 and silver indicator electrode; endpoint detected by potential change upon AgCl precipitation. |
| Sulfate | Barium Sulfate Gravimetric Method | Precipitation as BaSO4 in acidic medium, followed by filtration, drying, and weighing of the precipitate. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar (PCA) Method | Enumeration of viable aerobic microorganisms by colony formation on nutrient agar after incubation at 30-35 C for 48-72 h. |
| Yeast and Mold Count | Sabouraud Dextrose Agar (SDA) Method | Enumeration of viable yeasts and molds by colony formation on selective agar after incubation at 20-25 C for 5-7 days. |
| Related Substances (e.g., alpha-lactose, galactose, glucose) | HPLC with UV or RI Detection | Separation and identification of structurally related carbohydrates using gradient elution and retention time comparison. |
