Manufacturing Quality Control of D-(+)-Cellobiose
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with Refractive Index Detection | Quantifies D-cellobiose by separation on a carbohydrate-specific column and RI detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual inorganic matter. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral D-cellobiose in aqueous solution at specified concentration and temperature. |
| pH of Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in a 1% w/v aqueous solution using a calibrated glass electrode pH meter. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelength for lead. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after ignition with sulfuric acid treatment, indicating sulfate-forming impurities. |
| Related Substances | HPLC with UV Detection | Separates and detects structurally related impurities (e.g., glucose, cellobiosan, maltose) using reversed-phase or HILIC chromatography. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects aerobic mesophilic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form by analyzing angular scattering pattern of laser beam. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon heating to 105 C under controlled airflow. |
| Chloride Content | Ion Chromatography (IC) | Quantifies chloride ions after aqueous extraction by separation on anion-exchange column and conductivity detection. |
