Manufacturing Quality Control of DL-CARNITINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies the main component by titration with standardized HCl or NaOH based on its zwitterionic nature. |
| Water Content | Karl Fischer Titration | Measures water via iodine-sulfur dioxide redox reaction in a methanol-based solvent system. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated glass electrode in dilute aqueous solution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Detects heavy metals by formation of colored metal sulfide complexes under controlled pH. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Related Substances | Reverse-Phase HPLC | Separates and quantifies structurally similar impurities using C18 column and UV detection. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compound in solution using sodium D-line light. |
| Melting Point | Capillary Melting Point Determination | Determines temperature range at which solid transitions to liquid using calibrated apparatus. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Quantifies volatile content by mass loss upon controlled heating under inert atmosphere. |
| Microbial Limits | Membrane Filtration and Colony Counting | Assesses aerobic microbial contamination by filtration, membrane transfer, and incubation on agar media. |
