Napco Mark 600 Series Handheld Soil Analyzer is an important tool for soil and sediment screening. It can detect hazardous heavy metals within seconds. Using Napco Mark 600 for on-site rapid soil screening significantly reduces the number of samples that need to send to laboratory for analysis, reducing analysis costs and analysis time. And soil treatment and remediation costs can be minimized by rapidly screening and delineating contaminated areas and identifying remediation areas on-site.

How XRF Works?
XRF (X-ray Fluorescence) instantly identifies and measures the exact elemental composition of gold, silver, platinum and other metals – non-destructively, in seconds, with 99.99% accuracy.
Serving jewelers, refineries & labs worldwide
Whatever the size or complexity of your business – from a single pawn shop to an international refinery – we’re here to deliver fast, accurate and affordable XRF gold testing solutions tailored exactly to you.
- Instant gold purity & karat verification
- One-click ISO 9001-compliant reporting
- Full OEM/ODM customization + lifetime free software upgrades
Delivering instant, trustworthy results every time
Our advanced Fundamental Parameters (FP) algorithm automatically interprets the X-ray fluorescence spectrum and converts it into clear, accurate karat values and elemental percentages – even for complex alloys and plated items. No manual calibration curves needed, no guesswork.
- Real-time purity calculation with 99.99% accuracy
- Clear karat display and full elemental breakdown
- One-click professional PDF/Excel reports with spectrum & timestamp
Built for reliability, speed and everyday use
Napco XRF analyzers combine a high-performance micro X-ray tube, Peltier-cooled Si-PIN/SDD detector (140 eV resolution), and rugged industrial design to deliver stable, repeatable results 24/7 – even in busy jewelry shops and refineries.
- Long-life X-ray tube (thousands of hours) with auto-stabilization
