Here's a breakdown of VRAY's desktop XRF analyzer pricing, highlighting key factors influencing cost, followed by essential purchase considerations:
Model (VRAY) | Price Range | Key Influencing Factors |
VR-X3 | $6,000-$7,000 | Gas Proportional Detector, Solids only, 0.1% Accuracy, 50s Test Time |
VR-X5 | $10,000-$11,000 | Si-Pin Detector, Solid/Liquid/Powder, 0.05% Accuracy, 40s Test Time, Inbuilt PC |
VR-S6 | $12,000-$14,000 | Si-Pin Detector, Solid/Liquid/Powder, 0.03% Accuracy, 30s Test Time, Inbuilt PC, 11.6" Touchscreen |
When buying a desktop XRF analyzer, prioritize accuracy: Si-Pin detectors (VR-S6, VR-X5) offer superior precision (0.03-0.05%) over Gas Proportional (VR-X3, 0.1%). Assess test range (solids or multi-phase) and speed (30-50s). Consider integrated features like inbuilt PCs/touchscreens for ease. Also, evaluate X-ray tube power, collimator, and safety. Always choose a reputable brand with strong after-sales support and a good warranty for long-term reliability.
Choosing between a handheld XRF analyzer and a benchtop XRF analyzer depends entirely on your specific analytical needs. Handheld analyzers, like VRAY's VR-H5 (1.6Kg) or VR-M5 (4.1Kg), are your hero for on-the-go, instant, on-spot results. They excel when you're hopping between sites or need quick authentication in retail, offering rapid 30-second tests and impressive accuracy (e.g., VR-H5 at 0.03% for 9999 gold).
Conversely, benchtop analyzers are ideal for in-depth, precise analysis in a controlled environment, where consistency is paramount. VRAY's desktop models, such as the VR-S6 (also 0.03% accuracy for 9999 gold but with a stable lab setup) or the versatile VR-X5, are your best bet for achieving the highest analytical stability and often broader elemental analysis capabilities for confirmatory data in a dedicated lab setting.
Placement: Set up your analyzer on a stable, level surface in a controlled environment, away from extreme temperatures (ideally 10℃～35℃) or humidity.
Power On & Warm-up: Connect to a stable power source (e.g., 100W for VR-S6/VR-X5) and power on. Allow sufficient warm-up time; VRAY's T-shaped radiator minimizes waiting.
Calibration: Perform daily or regular calibration with certified reference materials to ensure optimal accuracy (e.g., 0.03% for VR-S6).
Sample Placement: Carefully place the sample within the chamber, ensuring it's flat and aligned properly beneath the X-ray window/collimator (e.g., ϕ2.5mm). Close the chamber door securely.
Analysis Settings: Select the appropriate test mode and parameters on the touchscreen (e.g., 11.6" for VR-S6) or integrated PC.
Start Test: Initiate analysis. Tests are fast (e.g., 30s for VR-S6, 40s for VR-X5).
Review Results: Interpret data displayed, then save or export results (e.g., via USB/Bluetooth).

Chamber Door: Always ensure the analyzer's chamber door is completely closed and interlocked before starting an analysis. X-ray emission is automatically prevented if the door is open.
No Tampering: Never attempt to bypass safety features or modify the device's internal components, software, or X-ray tube (50W, 50kV).
Authorized Personnel: Only trained and authorized personnel should operate the analyzer.
Radiation Monitoring: While modern desktop XRFs are well-shielded, regular checks for scattered radiation are recommended, especially if the unit is frequently moved or serviced.
Benchtop XRF analyzers are designed for highly precise, laboratory-grade elemental analysis. They excel at accurate material composition verification, ensuring product quality in manufacturing. These analyzers are indispensable for precious metal assaying, providing exact purity determinations for gold, silver, platinum, and palladium, crucial for valuation and anti-counterfeiting. They also facilitate non-destructive testing for quality control, preventing material mix-ups and ensuring compliance.
Benchtop XRF analyzers are primarily used in controlled environments. Common locations include quality control laboratories in metallurgy, electronics, and automotive industries. They are essential tools in jewelry manufacturing and appraisal shops, precious metal refineries, and recycling facilities for accurate sorting and valuation. Their robust design makes them suitable for research and development labs requiring consistent and precise elemental data.
Businesses and professionals requiring high-accuracy, consistent, and detailed elemental analysis benefit greatly. This includes jewelry manufacturers, pawnbrokers, and gold buyers needing to verify purity and authenticate precious metals. Metal recyclers and scrap dealers rely on them for rapid, accurate sorting and valuation. Furthermore, quality control departments across various manufacturing sectors use them to ensure material specifications are met. Anyone needing reliable, in-depth analytical data in a stable setting will find these analyzers invaluable.
Benchtop XRF analyzers offer exceptional precision, crucial for industries like jewelry, recycling, and metallurgy. Accuracy can vary based on the detector type; for instance, VRAY's VR-S6 and VR-X5 models, equipped with Si-Pin detectors, achieve high accuracies of 0.03% and 0.05% for 9999 gold, respectively. In contrast, models with Gas Proportional Detectors, like the VR-X3, typically offer around 0.1% accuracy for 999 gold. Factors influencing this precision include the X-ray tube power (e.g., 50W micro-focused tungsten tube), collimator size (e.g., ϕ2.5mm), and software algorithms. Regular calibration with certified reference materials is also vital for maintaining peak accuracy.
Benchtop XRF analyzers are designed with robust safety features to minimize radiation exposure. Their primary safety mechanism is a fully enclosed analysis chamber with interlocked doors, preventing X-ray emission when open. VRAY's analyzers also include efficient T-shaped radiators to manage heat, preventing overheating. While safe when used correctly, operators must never attempt to bypass safety interlocks or modify the internal components. Always keep hands and body clear of the X-ray beam path. Adhering strictly to the user manual's guidelines and ensuring only trained personnel operate the device is essential for safe operation.
The detection range of a desktop XRF analyzer varies by model and detector type. VRAY's Si-Pin detector models like the VR-X5 can detect a broad elemental range from Potassium (K, 19) to Uranium (U, 92). Models like the VR-X3 are optimized for specific precious metals, detecting elements like Au, Ag, Cu, Pt, Pd, Ir, and Cd. These analyzers can non-destructively test a variety of items including solids, liquids, and powders, making them ideal for jewelry, coins, dental alloys, industrial components, and even some environmental samples, depending on the specific analyzer's capabilities.
In case of a temporary hardware or software issue with your benchtop XRF analyzer, first, refer to the troubleshooting section of your user manual. For VRAY's models with inbuilt computers (like VR-S6 with i5-1035G7 Window 11 or VR-X5 with Intel i5 3320M), basic troubleshooting might include restarting the system or checking software settings. If the issue persists, avoid attempting complex repairs. Instead, contact VRAY's customer support team immediately. Our experienced technicians can provide remote assistance or guide you through necessary steps to resolve the malfunction, ensuring minimal downtime.
VRAY offers flexible customization options for our desktop XRF analyzers to meet diverse customer needs. Hardware customizations can include adjusting the X-ray tube power, target material (Ag, Au, W, Rh options), and collimator size (e.g., ϕ2.5mm) for optimized performance on specific samples. Software customization allows for tailored calibration algorithms, analysis modes, multi-language interfaces, and custom report formats to streamline your workflow. To choose the best model, consider your primary application, required accuracy (e.g., VR-S6 for highest precision), sample types (solids only vs. solid/liquid/powder), and budget. Consulting VRAY's expert team is highly recommended for personalized selection.
To purchase the best desktop XRF analyzer, focus on aligning the instrument's specifications with your application's demands. Look for key features like detector type (Si-Pin for high precision), test accuracy (e.g., 0.03% for VRAY's VR-S6), test speed (e.g., 30s), and the elemental range it can detect. Consider integrated features like touchscreens (e.g., 11.6" on VR-S6) and inbuilt computers for user experience.
