一. Clarify the detection requirements and accurately match the functions
1. Detection object and accuracy requirements
– **Conventional precious metal analysis** (such as pure gold, K gold, silver jewelry): Make sure the instrument supports **Au, Ag, Pt, Pd and other element detection**, and the accuracy must be ≤0.05%.
– **Special scenario requirements**:
– **Coating detection**: Gold plating auxiliary analysis software is required to support multi-layer coating measurement (up to 5 layers).
– **Adulteration identification** (such as rhenium-doped gold): Confirm whether the instrument has a preset “rhenium spectrum line” to avoid mistakenly counting impurities into the gold content.
**2. Sample morphology adaptability**
– **Large/irregular samples** (such as gold bars, crafts): Select a large sample cavity model (such as ≥410mm×330mm) to avoid cutting damage.
– **Micro samples** (gold wire, gold beans): Multi-size collimators are required to accurately focus on micro areas.
二. Core hardware configuration determines the upper limit of performance
1. Detector and resolution
– **Silicon drift detector (SDD)**: resolution ≤130eV, better than traditional Si-pin detector (160eV), can accurately separate element peaks and avoid overlapping interference.
– **Proportional counter**: low cost, suitable for basic component analysis, but limited resolution.
**2. Excitation source and stability**
– **High power X-ray tube** (50kV/50W): improve signal strength and shorten detection time (results within 60 seconds).
– **Optimal voltage regulator**: If the working environment voltage fluctuates, a purified voltage regulator must be installed to ensure data stability.
三. Use scenarios and extended functions to optimize efficiency
**1. Portability vs. laboratory accuracy**
– **On-site rapid screening** (recycling stores, mines): select a handheld spectrometer that supports IP54 dust and water resistance, -10℃~45℃ environment operation, and 1 second results.
– **Laboratory high-precision detection**: The desktop is equipped with a high-definition camera, automatic radiation protection device, and supports 4 decimal places of precision.
**2. Intelligence and compliance**
– **One-click intelligent analysis**: Unknown samples automatically match templates (such as 5800plus) to reduce the operating threshold.
– **Report and traceability**: When customizing reports, choose a computer printer; support data cloud storage to meet audit needs.
> **Industry anti-pit guide**: Beware of the “low-price gold bean trap”! Some rhenium-doped gold needs to be melted before the problem is exposed. When purchasing an instrument, be sure to confirm that it supports rhenium element identification to avoid 15%+ hidden losses.
