Manufacturing Quality Control of DL-Glutamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies DL-glutamine content by titration with standardized HCl or NaOH using a suitable indicator or potentiometric endpoint. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 C under vacuum to determine volatile and moisture content. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by incineration at 600-700 C followed by weighing of residual residue. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm identity and detect chiral impurities. |
| pH of Solution | Potentiometry | Determines hydrogen ion activity in aqueous solution using calibrated pH electrode. |
| Chloride | Argentometric Titration | Quantifies chloride ions by titration with silver nitrate using potassium chromate or potentiometric detection. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Heavy Metals (as Pb) | Colorimetric Limit Test | Forms colored complexes with dithizone under controlled pH; compared visually or spectrophotometrically against lead standard. |
| Iron | UV-Vis Spectrophotometry | Measures absorbance of Fe(II)-1,10-phenanthroline complex at ~510 nm. |
| Arsenic | Gutzeit Limit Test | Generates arsine gas from sample under acidic conditions, reacts with mercuric bromide paper to produce yellow stain. |
| Microbial Contamination | Membrane Filtration | Filters sample through sterile membrane, incubates on appropriate agar media, and enumerates colony-forming units. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using reversed-phase HPLC with UV detection at 210 nm. |
