XRF spectrometer Vanta GX-LT

energy dispersive X-ray fluorescenceX-ray fluorescencefor precious metals analysis

Product overview
The Vanta GX benchtop XRF analyzer provides nondestructive elemental analysis of precious metals for showroom and laboratory use. Designed for jewelers, pawn shops, coin dealers and metal buyers, the unit determines purity, karat classification and composition within seconds using proven XRF measurement methods.

Key capabilities

• Instant, nondestructive verification of gold, silver, platinum and other precious metals with no sample prep
• Detects up to 27 elements; configurable alerts for gold plating and hazardous elements
• Optional Silicon Drift Detector (SDD) for higher resolution (~30 eV) and increased count rates or PIN detector option for cost-sensitive applications
• Integrated full-color touchscreen and VGA camera for result display and documentation

Detection and performance
The Vanta GX provides rapid compositional readouts and impurity screening (e.g., lead, cadmium). Collimation options enable measurements on small features while minimizing matrix effects; typical workflows deliver repeatable results for pricing, acceptance and regulatory screening.

Models

• Vanta GX-LT: Cost-effective benchtop model with standard precision and a single 9 mm spot size for routine precious-metal testing.
• Vanta GX-LTS: High-throughput model with SDD option, higher precision and three spot sizes (9 mm, 3 mm, 1 mm) for complex jewelry and fine features.

Workflow and documentation

• Results display instantly on a bright touchscreen; external display output available for customer presentation
• Intuitive software with data export and cloud/PC integration for reporting
• Built-in camera pairs images with measurements for traceable records

Safety and compliance

• X-rays are emitted only when the lid is closed; shielded viewing window allows observation during analysis
• Visible safety indicators show X-ray emission status
• Designed for controlled, routine use in retail and lab environments

Value and warranty

• Bench solution that reduces reliance on destructive tests and accelerates transaction workflows
• Three-year standard warranty
• Two model choices let buyers match capability to budget

Applications
The Vanta GX is intended for countertop use in jewelry stores, pawn shops, cash-for-gold operations, museums, archaeological sites, coin dealers, scrap recycling and similar B2B environments. Typical uses include:

• On-the-spot gold measurement and karat (K) classification
• Identification of gold plating and assessment of gold/silver purity
• Detection of hazardous elements in jewelry (lead, cadmium)
• Compositional analysis of platinum, palladium and other precious metals
• Verification of metal content in coins and scrap
