Manufacturing Quality Control of D-Glutamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Specific Optical Rotation | [alpha]D measurement | Determination of optical activity using a polarimeter at specified temperature and concentration to confirm chiral integrity. |
| Water Content | Karl Fischer titration | Volumetric or coulometric titration with iodine-based reagent to quantify water via stoichiometric reaction. |
| Residue on Ignition | Gravimetric analysis | Heating sample to 700-800 C and weighing inorganic residue remaining after organic matter combustion. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, etc., by plasma excitation and atomic emission spectroscopy. |
| Chloride | Argentometric titration | Titration with standardized silver nitrate solution; endpoint detected by formation of AgCl precipitate or potentiometrically. |
| Sulfate | Barium chloride turbidimetry | Precipitation of sulfate as BaSO4 in acidic medium; quantification via turbidity measurement at 420 nm. |
| Related Substances | HPLC with UV detection | Separation and detection of structurally similar impurities (e.g., L-glutamine, pyroglutamine) using gradient elution. |
| pH of Solution | Potentiometric pH measurement | Measurement of hydrogen ion activity in aqueous solution (1% w/v) using calibrated glass electrode. |
| Microbial Contamination | Membrane filtration followed by plate count | Filtration of sample through sterile membrane, transfer to agar media, and enumeration of CFUs after incubation. |
| Loss on Drying | Thermogravimetric analysis | Weight loss measured after drying at 105 C for 2 hours under controlled atmospheric conditions. |
| Appearance | Visual inspection | Assessment of physical state, color, and clarity of solid material or aqueous solution against defined standards. |
