Manufacturing Quality Control of Silver
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Silver Content | Fire Assay | Sample is fused at high temperature, with lead collecting precious metals to form a lead button. Lead is then removed by cupellation, leaving a silver bead that is weighed for quantification. Highly accurate, suitable for high-purity silver and silver in ores. |
| Silver Content | Atomic Absorption Spectroscopy (AAS) | After dissolving the sample, it is atomized into a flame or graphite furnace, and absorbance at silver's characteristic wavelength (328.1 nm) is measured for quantification. High sensitivity and easy operation. |
| Silver Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | The sample solution is excited in a high-temperature plasma, and silver concentration is determined by measuring the intensity of its characteristic emission lines. Capable of multi-element analysis with a wide linear range. |
| Silver Content | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detects silver isotopes (e.g., ¹⁰⁷Ag, ¹⁰⁹Ag) using mass spectrometry. Extremely high sensitivity, suitable for trace silver analysis. |
| Silver Purity | X-Ray Fluorescence Spectroscopy (XRF) | Non-destructive testing method that analyzes characteristic X-rays emitted from the sample to determine silver content and purity based on peak intensity. Suitable for rapid screening of jewelry and bulk materials. |
| Impurity Elements in Silver | ICP-MS / ICP-OES | Simultaneously detects various impurity elements in silver (e.g., Cu, Pb, Fe, Ni), enabling assessment of material purity. Widely used in quality control of high-purity silver. |
| Silver Coating Thickness | X-Ray Fluorescence Coating Thickness Analyzer (XRF) | Uses X-rays to excite both the silver coating and substrate; coating thickness is calculated from the fluorescence intensity ratio. Non-destructive, fast, and suitable for electroplated products. |
| Silver Chemical Form | Chemical Titration (e.g., Argentometric Method) | Uses standard silver nitrate solution to titrate chloride ions (Cl⁻), or sodium chloride to titrate silver ions (Ag⁺), based on precipitation reactions to quantify silver. Commonly used for Ag⁺ determination in solutions. |
| Silver Microstructure | Scanning Electron Microscopy (SEM) + Energy Dispersive Spectroscopy (EDS) | Examines surface morphology of silver materials and combines elemental analysis (point or mapping) via EDS to study impurity distribution and phase structure. |
