Manufacturing Quality Control of α-Cyclodextrin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | HPLC with refractive index detection | Quantifies alpha-cyclodextrin by separation on a carbohydrate-specific column and RI detection relative to a certified reference standard. |
| Loss on drying | Gravimetric thermogravimetry at 105 C | Measures mass loss after drying at 105 C for 2 h, indicating volatile content including residual water and solvents. |
| Residue on ignition | Gravimetric ash analysis at 600 C | Determines inorganic impurities by incinerating sample at 600 C and weighing the non-volatile residue. |
| Heavy metals (as Pb) | ICP-OES | Quantifies total heavy metals by plasma excitation and elemental emission spectroscopy after acid digestion. |
| Chloride content | Potentiometric titration with AgNO3 | Measures chloride ions via argentometric titration using silver nitrate and a silver electrode endpoint detection. |
| Sulfate content | Turbidimetric assay with BaCl2 | Forms barium sulfate precipitate; quantifies sulfate based on turbidity measured at 420 nm. |
| Specific optical rotation | Polarimetry at 20 C and 589 nm | Determines enantiomeric purity and identity by measuring angle of rotation of plane-polarized light in aqueous solution. |
| pH of 10% aqueous solution | Potentiometric pH measurement | Evaluates acidity/basicity of solution using calibrated glass electrode in standardized 10% w/v dispersion. |
| Microbial contamination | Membrane filtration followed by aerobic plate count | Quantifies viable aerobic microorganisms by filtration, membrane transfer to TSA agar, and colony enumeration after incubation. |
| Related substances | HPLC with UV detection | Separates and detects structurally similar impurities (e.g., beta-, gamma-cyclodextrin, linear oligosaccharides) using gradient elution and UV at 195 nm. |
| Particle size distribution | Laser diffraction | Measures volume-based particle size distribution in suspension using Mie scattering theory and optical detection. |
| Water content | Karl Fischer coulometric titration | Determines trace water by electrochemical generation of iodine and stoichiometric reaction with sample water. |
