Advanced Detector Technology

High-Performance Silicon Drift Detector

The analytical heart of ElvaX Plus is a large-area silicon drift detector with 25 square millimeter active area—significantly larger than detectors in many competing systems. This substantial detector area captures more fluorescent X-rays from samples, improving sensitivity and reducing required measurement times.

Energy resolution specifications of approximately 140 eV at manganese Kα and 85 eV at aluminum Kα enable clear separation of closely-spaced spectral peaks from different elements. Superior resolution proves critical when analyzing complex multi-element matrices where overlapping peaks might confuse less capable systems.

The detector achieves remarkable count rate capacity exceeding 400,000 counts per second, with some specifications listing capability to 500,000 CPS. This high throughput enables rapid accumulation of statistically significant data, supporting fast analysis without sacrificing precision.

This digital architecture delivers stable, reproducible spectra supporting long-term calibration stability essential for quality control laboratories.

Optimized for Light Element Analysis

Helium Purge Capability

Light element detection—sodium, magnesium, aluminum, silicon, phosphorus, sulfur—presents challenges for standard air-path XRF systems because low-energy X-rays from these elements are absorbed by air between sample and detector. ElvaX Plus addresses this limitation through optional helium purge operation.

The helium atmosphere replaces air in the measurement chamber, dramatically reducing absorption of low-energy X-rays. This enhancement extends practical detection limits for light elements, enabling reliable quantification where standard air-path systems struggle. Applications involving polymers, ceramics, minerals, and many industrial materials benefit substantially from improved light element sensitivity.

The helium purge operates efficiently, consuming modest helium quantities while maintaining analysis convenience. Laboratories gain light element capabilities without the complexity and cost of full vacuum systems required for ultimate light element performance.

Automatic Primary Filter Changer

ElvaX Plus features automatic primary filter changing that optimizes excitation conditions for different elements without operator intervention. The system automatically selects appropriate filters based on measurement method, ensuring optimal excitation efficiency across the periodic table.

This automation improves analytical performance by matching excitation to sample characteristics while eliminating manual filter changes that slow workflows and introduce potential errors. The filters reduce spectral background, minimize matrix effects, and enhance sensitivity for specific element groups.

Diverse Sample Handling Capabilities

Benchtop XRF's practical advantage lies in accommodating diverse sample types through standardized presentation. ElvaX Plus handles solid samples including metal coupons, rock fragments, and manufactured products; pressed powder pellets prepared from heterogeneous materials; liquids in specialized sample cups; and thin films or coatings on various substrates.

The standard sample chamber accepts samples up to specified dimensions, while manual positioning ensures proper alignment for reproducible measurements. Optional upgrades expand capabilities further: a 16-position automatic sample changer enables unattended sequential analysis of multiple samples, dramatically increasing throughput for high-volume laboratories.

An optional high-resolution CCD camera provides visual sample positioning verification, ensuring consistent measurement locations for non-uniform samples or when analyzing specific features. This imaging capability proves valuable for quality documentation and method development.
