| Industrial | Rubber vulcanization accelerator; auxiliary in electro-galvanizing | High-temperature reaction; electrochemical deposition |
Manufacturing Quality Control of Zinc glycinate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Zinc Content | Atomic Absorption Spectroscopy (AAS) | Measures the characteristic absorption peak of zinc using an atomic absorption spectrometer to quantitatively determine zinc concentration. |
| Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | The sample is nebulized and excited in a high-temperature plasma; zinc is quantified by detecting its characteristic emission spectrum. | |
| Glycine Content | High-Performance Liquid Chromatography (HPLC) | Glycine is separated on a reversed-phase column and detected using UV or evaporative light scattering detection, with quantification by external standard method. |
| Titration Method (Non-aqueous Titration) | Glycine's basic groups are titrated with a perchloric acid standard solution in a non-aqueous solvent to calculate its content. | |
| Complexation/Binding Rate | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Free zinc reacts with a chromogenic reagent (e.g., PAR) to produce color; uncomplexed zinc is measured to indirectly calculate the complexation rate. |
| Dialysis combined with AAS/ICP | Free zinc and bound zinc are separated by dialysis, individually measured, and the binding ratio is calculated. | |
| Appearance | Visual Inspection | Observe color, physical state, and presence of visible foreign matter under natural or standard lighting conditions. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Sample is dried to constant weight at 105°C; the percentage weight loss indicates moisture and volatile content. |
| Sulfated Ash / Residue on Ignition | Sulfuric Acid Ashing Method | Sample is charred, treated with sulfuric acid, then ignited at high temperature to constant weight; residue is weighed. |
| Total Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determines total content of toxic heavy metals such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmacopoeial or food safety standards. |
| Microbial Limits | Microbial Limit Test (Chinese Pharmacopoeia) | Tests for total aerobic microbial count, total mold and yeast count, and specified pathogens (e.g., Escherichia coli, Salmonella). |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Uses laser scattering principle to measure particle size distribution, evaluating product uniformity and solubility. |
| pH Value | pH Meter Method | Sample is prepared as an aqueous solution of defined concentration; pH is directly measured using a calibrated pH meter. |
| Content Uniformity | HPLC or AAS | Main component content is measured in multiple individual units to assess dose-to-dose consistency (applicable to dosage forms). |
