Portable XRF Analyzer: ElvaX Mobile Model

Understanding the Mobile Concept

The ElvaX Mobile occupies a distinct niche between stationary benchtop systems and handheld analyzers. Weighing approximately 5.5 kilograms with dimensions of 380 × 270 × 160 millimeters, this portable analyzer packs into a protective carrying case transforming into a complete analytical workstation when deployed. The design prioritizes benchtop-style measurement geometry and sample handling while achieving field portability through compact integration and battery operation.

The key distinction lies in sample presentation. Where handheld analyzers test materials as encountered through direct surface contact, ElvaX Mobile uses a sample tray accommodating XRF sample cups—the standard containers for liquids, powders, and prepared specimens. This approach delivers superior analytical performance for materials requiring controlled sample presentation, homogenization, or containment during measurement.

The mobile deployment enables testing at remote locations, temporary field sites, or multiple facilities without permanent laboratory installation. Set up on any flat surface—field tables, equipment cases, vehicle tailgates—perform measurements, then pack the analyzer for transport to the next location. This flexibility proves invaluable for exploration projects, environmental investigations, agricultural surveys, and applications requiring analytical capability at changing locations.

Technical Capabilities

Advanced Detection System

ElvaX Mobile incorporates silicon drift detector technology delivering energy resolution around 140 eV at manganese Kα when equipped with the optional SDD detector. Standard Si-PIN detector configurations provide reliable performance at accessible pricing. The detector area—6 square millimeters for PIN, 25 square millimeters for SDD—captures fluorescent X-rays efficiently supporting rapid analysis and trace element sensitivity.

The large measurement spot compared to handheld analyzers ensures representative sampling of heterogeneous materials. Powders, soils, and granular samples receive analysis averaging larger sample volumes, improving result reproducibility and reducing sampling errors that affect small-spot measurements. Optional sample spinners further enhance averaging for inhomogeneous specimens.

Count rate capabilities combined with Dynamically Adaptive Shaping digital pulse processing enable rapid measurements. The proprietary DAS technology with 80 MHz sampling rate optimizes both resolution and throughput, supporting quick field analysis without sacrificing data quality. The 4096-channel multi-channel analyzer provides fine spectral resolution across the full energy range.

Flexible Excitation System

The digiX X-ray source operates at 40 kV (or optional 50 kV) maximum voltage with 200 microamp current delivering 4-5 watts power. Tungsten anode tubes provide versatile excitation; optional rhodium or silver anodes optimize performance for specific element groups. The five-position automatic filter changer selects optimal primary beam filtering for different materials and measurement methods, improving signal-to-background ratios and element sensitivity.

This sophisticated excitation system rivals benchtop spectrometers while remaining portable through efficient compact design. The variable voltage and automatic filter selection optimize analytical conditions for diverse sample types from heavy metal soils to light element minerals to liquid petrochemicals.

Integrated Electronics and Display

Ideal Applications for Mobile Deployment

Soil and Environmental Analysis

Environmental investigations employ ElvaX Mobile for field soil screening during site assessments and remediation projects. The sample cup capability enables testing homogenized soil samples prepared on-site, providing more representative results than surface scanning heterogeneous materials. Multiple samples collect across investigation areas, homogenize in field, transfer to sample cups, and analyze immediately providing same-day contamination mapping.

The portable deployment eliminates sample transport to distant laboratories and multi-week analytical delays. Environmental consultants carry ElvaX Mobile to sites, conduct comprehensive testing during field mobilization, and deliver preliminary reports before leaving locations. This efficiency reduces project costs and accelerates remediation planning.

Mining and Geological Exploration

Exploration projects utilize ElvaX Mobile for field ore grade determination and geochemical characterization. Rock samples collected from outcrops or drill core undergo crushing and homogenization at field camps, then transfer to sample cups for analysis. The controlled sample presentation ensures representative measurements from heterogeneous geological materials.

The mobile laboratory approach provides benchtop-quality results in remote locations lacking permanent facilities. Exploration geologists establish temporary field laboratories at base camps, processing and analyzing samples as drilling progresses. The immediate geochemical feedback guides tactical drilling decisions optimizing exploration efficiency.

Agricultural and Food Testing

Agricultural applications employ ElvaX Mobile for nutrient analysis in soils and plant materials. The ability to analyze prepared samples in cups suits agricultural matrices better than direct surface scanning. Soil samples from fields undergo standardized preparation, analysis delivers nutrient profiles guiding fertilization decisions, all performed on-farm without laboratory transport.

Food safety testing benefits from mobile deployment enabling on-site screening at production facilities, distribution centers, or border inspection stations. Liquid and powder food products transfer easily to sample cups for rapid elemental analysis supporting contamination screening and quality verification.
