Manufacturing Quality Control of Zinc methionine sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Zinc Content | ICP-OES | Quantifies Zn by measuring atomic emission intensity of excited Zn ions in plasma. |
| L-Methionine Content | HPLC-UV | Separates and quantifies L-methionine using reversed-phase chromatography and UV detection at 210 nm. |
| Loss on Drying | Gravimetric (Thermogravimetry) | Measures mass loss after drying at 105 C to determine volatile content including water and solvents. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Detects trace heavy metals by ionizing samples in plasma and measuring mass-to-charge ratios with high sensitivity. |
| Insoluble Matter | Filtration and Gravimetry | Determines undissolved particles by filtration through a defined pore-size membrane followed by drying and weighing. |
| pH (1% aqueous solution) | Potentiometric Titration | Measures hydrogen ion activity using a calibrated pH electrode in a standardized suspension. |
| Sulfate Content | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration, washing, and drying. |
| Total Plate Count | Plate Count Agar Culture | Estimates viable aerobic microorganisms by colony formation on nutrient agar after incubation at 30-35 C for 48-72 h. |
| Yeast and Mold Count | Sabouraud Dextrose Agar Culture | Quantifies yeasts and molds by colony enumeration on selective agar after incubation at 20-25 C for 5-7 days. |
| Residual Solvents (e.g., methanol, ethanol) | GC-FID | Separates and quantifies volatile organic solvents using gas chromatography with flame ionization detection. |
| Chelation Ratio (Zn:Methionine molar ratio) | Combined ICP-OES and HPLC-UV | Calculates molar ratio from independently quantified Zn and L-methionine concentrations. |
| Appearance (Color and Physical Form) | Visual Inspection | Assesses uniformity, color, and physical state (e.g., free-flowing powder) under controlled lighting against standard references. |
