Manufacturing Quality Control of Zinc glycinate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Zinc Content | Atomic Absorption Spectroscopy (AAS) | Quantifies Zn by measuring absorption of light at characteristic wavelength after atomization in flame or graphite furnace. |
| Glycine Content | Acid-Base Titration | Determines free glycine by titration with standardized NaOH using phenolphthalein indicator. |
| Assay (C2H6N2O2Zn) | UV-Vis Spectrophotometry | Measures absorbance of complexed glycine zinc at specific wavelength after derivatization or direct analysis in solution. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Determines volatile content by measuring mass loss after drying at specified temperature and time. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-OES | Simultaneously quantifies multiple heavy metals by measuring element-specific emission intensities from plasma-excited sample. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions via titration with AgNO3 using silver indicator electrode to determine endpoint potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetric Method | Precipitates sulfate as BaSO4 and determines content by weighing the dried precipitate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in a defined suspension or solution. |
| Residue on Ignition | Gravimetric (Ashing) | Determines inorganic impurities by measuring residue mass after high-temperature ignition of sample. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in intensity of laser light scattered by dispersed particles. |
| Microbial Contamination | Membrane Filtration | Captures microorganisms from solution on sterile membrane filter, followed by incubation and colony enumeration. |
| Water-Soluble Matter | Gravimetric Filtration | Determines soluble fraction by dissolving sample, filtering, evaporating filtrate, and weighing residue. |
