Implementation Tips for Napco XRF Analyzers
Quick-Start Best Practices
- Place the analyzer on a stable, vibration-free surface (avoid counters near stamping machines or heavy foot traffic).
- Use the provided sample cups and protective films for loose scrap or irregular pieces to prevent contamination and ensure repeatable results.
- Perform daily energy calibration (takes <60 seconds) using the included standard reference block – this guarantees long-term 99.99% accuracy.
- Train all staff in under 2 hours: the touchscreen interface is designed for non-technical users (jewellers, cashiers, security officers).
- Connect to your network or Wi-Fi for automatic software updates and cloud backup of test reports.
Common Challenges & Proven Solutions
| Challenge | Solution with Napco XRF |
|---|---|
| Inconsistent results between branches | Centralized calibration standards + cloud-synced settings ensure identical results across all locations |
| Staff afraid of radiation | Fully enclosed chamber + triple safety interlocks – safer than a dental X-ray; no special license required in most countries |
| Testing coated or plated jewelry | Automatic “plating detection mode” instantly flags thickness and base metal beneath gold layer |
| Small or oddly shaped items | Included collimators (1 mm–10 mm spot size) + adjustable stage handle rings, earrings, chains, and nuggets effortlessly |
| Need legal/certified reports for loans | Built-in printer + PDF export with timestamp, serial number, and company logo – accepted by banks and insurers worldwide |
| High sample volume during peak hours | 30-second test cycle + batch mode allows 120+ tests per hour without fatigue |
