Manufacturing Quality Control of L-Arabinose
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with Refractive Index Detection | Quantifies L-Arabinopyranose concentration by comparing peak area against calibrated standard solutions. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light induced by chiral L-arabinopyranose in solution. |
| Water Content | Karl Fischer Titration | Determines water content via stoichiometric reaction between water and iodine in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by atomic emission spectroscopy after acid digestion. |
| Chloride Content | Potentiometric Titration with Silver Nitrate | Detects chloride ions based on potential change during AgNO3 titration forming AgCl precipitate. |
| Sulfate Content | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities (e.g., D-arabinose, arabinofuranose) using gradient elution. |
| Microbial Limits | Membrane Filtration and Plate Count | Determines aerobic microbial contamination by filtration, culture on TSA, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution based on angular scattering pattern of laser beam. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid L-arabinopyranose transitions to liquid phase under controlled heating. |
