The handheld format enables real-time manufacturing and shipment verification, allowing trained operators to check materials anywhere in the facility or supply chain. Portable onsite screening eliminates delays associated with sending samples to external laboratories, providing immediate pass/fail results for compliance decision-making. The ProSpector 3, the latest generation, delivers performance that transforms perceptions of portable XRF capabilities.​​

Advanced Detection Technology

ElvaX analyzers utilize Silicon Drift Detector (SDD) technology combined with Dynamically Adaptive Shaping (DAS) digital pulse processing developed by Elvatech. This combination makes the ProSpector one of the fastest handheld XRF analyzers available, operating at count rates exceeding 500,000 counts per second. The Fast SDD detector delivers exceptional sensitivity, enabling detection of hazardous elements at trace concentrations well below regulatory limits.

The detector system provides accurate measurement of lead, mercury, chromium, cadmium, and bromine (as an indicator for PBB and PBDE flame retardants). High-speed operation combined with advanced signal processing ensures precise results within seconds, supporting high-throughput testing scenarios. Detector protection features and ambient temperature/pressure corrections maintain stability across varying environmental conditions.​

Small Spot Analysis Capability

Small spot analysis represents a critical capability for successful RoHS screening, since the analysis beam must match individual component sizes. Electronic assemblies contain numerous small components including resistors, capacitors, connectors, and integrated circuits that require individual testing. The ElvaX analyzers feature selectable collimators that adjust the X-ray beam size to match sample dimensions.

Collimator options ranging from 0.4 mm to 1.5 mm or larger enable accurate analysis of tiny individual components, cables, bulk samples, and large circuit boards. This flexibility ensures that measurements target specific components rather than averaging across multiple materials, which could mask non-compliant elements in small parts. The small spot capability proves essential when testing heterogeneous assemblies containing various materials.

Pass/Fail Feature for Quick Decisions

Modern portable XRF analyzers incorporate pass/fail features that simplify inspection of incoming materials for RoHS compliance. The system automatically compares detected element concentrations against programmed threshold values and displays clear pass or fail indicators. This functionality enables operators without extensive analytical training to make immediate compliance decisions.​

The pass/fail feature proves particularly valuable at receiving docks where rapid screening of supplier shipments prevents non-compliant materials from entering production. Visual and audible indicators alert operators to potential compliance issues, triggering immediate investigation or rejection protocols. The system can also verify that materials are halogen-free when required by specific customer specifications

Non-Destructive Testing Advantage

X-ray fluorescence provides non-destructive analysis that preserves sample integrity, allowing tested items to remain in inventory or be returned to production. Unlike destructive chemical testing methods that consume samples, XRF screening leaves products completely intact. This capability proves especially valuable when testing finished goods or expensive components where sample destruction would represent significant cost.

Non-destructive testing enables comprehensive screening programs where manufacturers can test 100% of production rather than relying on statistical sampling. The ability to analyze complete assemblies without disassembly accelerates testing workflows and maintains product cleanliness standards. Components that pass XRF screening proceed directly to the next production stage or shipment without delay.​

Extended Battery Life for Field Work

The ElvaX ProSpector features extended battery operation exceeding 10 hours on a single charge. This exceptional battery life enables full-day field inspections without recharging interruptions, supporting comprehensive supplier audits, production monitoring, and warehouse screening operations. The long battery runtime proves essential for mobile compliance verification programs where testing occurs across multiple locations.

Portable Bluetooth printers provide measurement printouts at any time and anywhere, creating immediate documentation for compliance records. Shock and water-resistant carrying cases protect the instrument during transport between testing locations. A holster with belt straps keeps the analyzer readily accessible during extended inspection sessions.

Multiple Testing Configurations

The ElvaX ProSpector supports various testing configurations to accommodate different sample types and sizes. For small objects or light matrix samples, a laboratory stand prevents X-ray scattering and improves measurement accuracy. The stand configuration also enables hands-free operation for repetitive testing of similar components.

Specialized adaptors for weld joint analysis focus the X-ray spot precisely on the weld while excluding surrounding material. This targeted approach ensures accurate assessment of weld composition rather than averaging across base metals. The system provides full compatibility with ElvaX PC software for advanced data management, custom reporting, and statistical analysis.

Cost-Effective Screening Strategy

RoHS XRF screening provides a cost-effective method to determine compliance levels in products and parts. The technology focuses resources on components with the highest risk of containing restricted substances, optimizing testing efficiency. When XRF screening indicates that samples do not contain RoHS substances above legal thresholds, the need for expensive wet chemical analysis, ICP, UV-VIS, or GC-MS confirmation testing is substantially reduced.​

This pre-screening approach minimizes laboratory costs while maintaining compliance assurance throughout production. Manufacturers implementing in-house XRF screening can test thousands of samples at the marginal cost of operator time, compared to hundreds of dollars per sample for external laboratory analysis. The investment in ElvaX equipment typically achieves return on investment within months for organizations with significant testing volumes.

Comprehensive Application Range

Beyond RoHS compliance, ElvaX analyzers support extensive application ranges including WEEE directive compliance, Proposition 65 screening, alloy analysis, mining and exploration, precious metals testing, lead in paint detection, and archeometry. This versatility enables organizations to consolidate multiple analytical needs into a single instrument platform.

The ProSpector excels at environmental analysis, soil and sediment screening, catalyst converter analysis, coating thickness measurement, and forensic applications. This broad capability transforms the analyzer from a single-purpose compliance tool into a comprehensive analytical platform serving diverse organizational needs. The extensive and editable grade libraries support virtually any material analysis requirement.

Safety and Ergonomic Design

ElvaX analyzers incorporate comprehensive radiation safety features including infrared proximity sensors and low count detection that immediately shut down X-ray emission if the analyzer is pointed at unintended targets. Protective films on detector windows prevent contamination while allowing X-ray transmission, with tool-free replacement enabling rapid field maintenance.

The ergonomic handheld design with balanced weight distribution reduces operator fatigue during extended inspection sessions. Intuitive user interfaces allow even novice operators to perform measurements in seconds after minimal training. When X-rays are emitting, blinking indicator lights and audible signals alert nearby personnel, enhancing workplace safety during testing operations.​
