ElvaX Plus: Benchtop Light Elements Helium

Understanding the Light Element Challenge

Why Light Elements Are Difficult to Detect

Light elements (Na, Mg, Al, Si, P, S) emit low-energy X-rays that are strongly absorbed by air on the path to the detector. This causes severe signal loss or complete disappearance in standard air-mode XRF, making reliable detection very challenging with traditional benchtop analyzers.

The Helium Purge Solution

Helium purge replaces air in the measurement gap with helium gas — a light, low-absorption medium. This simple change dramatically reduces signal attenuation, significantly improving detection limits and accuracy for light elements. ElvaX Plus integrates helium purge as a core feature, enabling full Na–U analysis with high performance.

Technical Excellence of ElvaX Plus

• Large-area Silicon Drift Detector (40 mm²) — high resolution and sensitivity for faint signals
• 60 kV / 1000 µA tube — enhanced excitation for light and mid-range elements
• Throughput >400,000–500,000 cps — among the fastest benchtop XRF systems
• Automatic 8-position primary filter changer — optimized excitation for any element group
• Helium purge — multiplies light-element sensitivity

The Helium Advantage – Quantified
