Manufacturing Quality Control of D(+)-Raffinose pentahydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-RI | Quantifies D(+)-raffinose pentahydrate by separation on a carbohydrate column with refractive index detection, using external standard calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration based on the reaction of iodine with water in a methanol-based reagent. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified concentration and temperature. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 500-600 C and weighing the residual non-volatile material. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (e.g., Pb, Cd, As, Hg) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride | Potentiometric Titration | Determines chloride ion concentration by titration with silver nitrate using a silver indicator electrode and reference electrode. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under acidic conditions and determines content by drying and weighing the precipitate. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass and reference electrodes. |
| Microbial Limits | Membrane Filtration | Detects aerobic mesophilic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., sucrose, raffinose anhydrous, melibiose) using reversed-phase or HILIC chromatography with UV detection. |
| Iron | AAS | Quantifies iron content after sample digestion by measuring atomic absorption at 248.3 nm in an air-acetylene flame. |
| Loss on Drying | Thermogravimetry | Determines volatile matter (including residual solvents and loosely bound water) by weight loss upon heating at 105 C for 2 hours. |
