X-Ray Fluorescence spectrometers

Elvatech's portable XRF (X-ray fluorescence) analyzers let you determine the elemental composition of a sample in seconds, without cutting it, damaging it, or sending it to a lab. Point the device at a surface, and its built-in X-ray tube causes the sample's atoms to fluoresce; a detector reads that fluorescence and the onboard software reports the elements present, covering the full range from sodium to uranium in the periodic table.

The ProSpector 2 is a handheld EDXRF metal analyzer with a count rate above 500,000 CPS, automatic correction for pressure and temperature drift, more than 10 hours of battery operation, a protected detector, a large customizable alloy library, and ElvaX PC software for transferring results to a computer.

The ProSpector 3 is the newer generation: it weighs just 1.05 kg, is IP-67 waterproof and dustproof (it can even analyze underwater), automatically adjusts for small objects and spots (useful for jewelry testing), runs 16 hours on one charge, has a folding display for standalone operation, needs no manual calibration, and uses two CCD cameras for combined micro and macro sample viewing, with WiFi, Bluetooth, USB and a microSD slot.

The ElvaX Geo is built for mining and exploration: it analyzes unknown samples without manual calibration, reduces error on inhomogeneous geological samples, can be turned into a benchtop instrument with an optional stand, and supports GPS logging via Bluetooth in a watertight housing.

The ElvaX Mobile combines automatic pressure/temperature compensation with an integrated PDA for handheld operation, and can be fitted with an optional CCD camera for sample positioning and an optional sample spinner for more precise averaging.

Typical applications include alloy identification and positive material identification, RoHS and consumer-goods screening, archaeometry and art authentication, oil and fuel analysis, and soil and environmental screening — all with no meaningful damage to the sample and negligible radiation exposure to the operator.

A benchtop XRF spectrometer is a compact, high-precision X-ray fluorescence analyzer that stands on a laboratory bench or production-line table. Unlike a handheld XRF gun, it measures inside a fully enclosed chamber with fixed, stable geometry and advanced X-ray optics, which gives excellent repeatability, very low detection limits and comfortable routine operation across a wide range of sample types – solids, loose powders, pressed pellets, films and liquids.

Elvatech offers several benchtop models to match different tasks and budgets. The ElvaX Basic is a cost-effective EDXRF spectrometer for routine laboratory and production control. The ElvaX Plus is a versatile analyzer with extended configuration options for a wide application range. The ElvaX Pro is the most powerful model in the family, built for demanding analytical tasks that need the lowest detection limits. The ElvaX Jewelry Lab is a compact counter-top instrument optimized for jewelry, precious metals and hallmarking laboratories. The ElvaX RoHS is a dedicated spectrometer for fast RoHS and hazardous-elements screening in electronics and consumer goods. The ElvaX S Lab is specialized for sulfur determination in petroleum products across a wide concentration range.

Typical applications include identification of alloy grades and melt control in metals and alloys, sulfur and other element determination in oil and petrochemical products, control of raw materials and finished cement, RoHS screening of electronics and plastics, analysis of gold, silver and platinum alloys and detection of hazardous elements such as cadmium or nickel in jewelry, and analysis of soils, sediments and ores for environmental and geological work.

Every benchtop XRF analyzer from Elvatech is a fully enclosed system with interlocks that prevent operation while the chamber is open, keeping operator dose negligible without any special room shielding. Final configuration – X-ray tube type and power, detector type and size, need for helium purge for light elements, number of calibrations and optional sample changers – is matched to the customer's specific analytical tasks.

Elvatech's specialized-task XRF systems are built for applications that don't fit a standard handheld or benchtop analyzer. The PmX-5050 is a continuous elemental analyzer for heavy metals in ambient air, providing ongoing monitoring rather than a single spot measurement – suited to environmental agencies and industrial sites that need to track airborne metal concentrations over time. The ElvaX Art is designed specifically for the non-destructive analysis of paintings, sculptures and other art and heritage objects, allowing conservators and researchers to identify pigments, metals and other materials without taking a physical sample from the artwork.

Both instruments share Elvatech's core energy-dispersive X-ray fluorescence (EDXRF) technology: an X-ray tube irradiates the sample, causing its atoms to emit characteristic fluorescent X-rays, which a detector measures and the instrument's software converts into elemental concentrations. Because the interaction happens at the level of individual atoms, XRF analysis does not alter or damage the sample – a decisive advantage when working with irreplaceable art objects or when continuous, unattended monitoring is required.

Elvatech's broader XRF portfolio (handheld ProSpector and ElvaX Geo/Mobile analyzers, benchtop ElvaX Basic/Plus/Pro/Jewelry Lab/RoHS/S Lab spectrometers, and these specialized systems) is used across mining, metal recycling, environmental testing, pharmaceuticals and consumer-goods industries, giving fast, accurate, non-destructive elemental composition data with detection limits reaching parts-per-million levels for many elements.
