Manufacturing Quality Control of BETA-D-GLUCOPYRANOSYL(1-4)-D-GLUCOPYRANOSE
| 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. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light induced by chiral D-(+)-cellobiose in solution at specified concentration and wavelength. |
| Water Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water and iodine in a methanol-based reagent, monitored electrometrically. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing of the sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing the acid-digested sample and measuring absorbance at characteristic wavelengths for lead. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic sulfate residue after combustion with sulfuric acid treatment and subsequent weighing. |
| Related Substances | HPLC with UV Detection | Separates and detects structurally related impurities (e.g., glucose, cellobiosan, oligosaccharides) using reversed-phase or HILIC chromatography. |
| pH of Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined aqueous solution using a calibrated glass electrode system. |
| Clarity and Color | Visual Comparison / Spectrophotometry | Evaluates solution clarity against Grade I water and color by comparison to platinum-cobalt standards or absorbance at 420 nm. |
| Microbial Contamination | Membrane Filtration / Plate Count | Quantifies aerobic mesophilic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Determines volatile matter loss by measuring weight change after drying at 105 C under controlled conditions. |
| Reducing Sugars | Fehling's Titration | Measures reducing end groups via redox titration with alkaline copper tartrate solution, using methylene blue as endpoint indicator. |
