State-of-the-Art Components for Highest Flexibility

With its fully digitally mastered 6^th generation goniometer, the ARL PERFORM’X spectrometer now offers faster and more precise results.

The goniometer can be configured to do qualitative analysis, which includes searching the X-Ray spectrum for elements in a particular sample, or quantitative analysis on specific elements. This state-of-the-art compact goniometer gives analysts more application options with up to nine analytical crystals and four collimators.

Up to 25% more elemental signal count rates are possible because to the extremely small goniometer technology. Better counting statistics are produced at high count rates by enhanced detector linearity.

The analytical range is further expanded by installing seven primary X-Ray beam filters, which also minimize interference from X-Ray tube emission lines on some elements and significantly enhance peak-to-background ratios for most elements.

Additional optional features, such the 4-position programmed aperture changer, extend the variety of sample types that can be investigated. Three additional apertures are configurable, with the following diameters available in addition to the normal 29 mm aperture: 0.5, 1.5, 5, 10, 15, 20, 25, and 35 mm to make it easier to examine samples of various sizes.

Outstanding long-term stability is provided by the X-Ray tube’s LoVap filament technology, which runs at a lower temperature and removes drift caused by tungsten vapor plating on the beryllium tube window. Improving the X-Ray tube cone also enables a closer interaction between the anode and sample. This leads to lower detection limits and higher sensitivity for each element in the periodic table.

Fast and Accurate Analysis

Fast Qualitative Analysis

Peaks can be defined with 0.001° accuracy using step scanning. Continuous digital scanning is perfect for quick qualitative investigation since it can record spectra at up to 500° per minute. Peaks are automatically recognized as the components that are present.

Accuracy Made Easy

Analytical programs and calibrations can be quickly and precisely defined with the help of the online Analytical Assistant. The software called multi-variable regression (MVR) is used to produce calibration curves. By reducing the impact of interfering components in multi-component matrices, correction models increase the precision of the analysis. The models are:

Line overlap correction

Additive correction on intensities

Additive correction on concentrations

Multiplicative correction on intensities

Multiplicative correction on concentrations

Multiplicative and additive corrections on concentrations

The NBSGSC fundamental parameters software uses Comprehensive Lachance (COLA) with 3-term alphas to duplicate analytical calibrations for homogeneous materials. Inter-element correction factors (theoretical alphas with matrix and LOI/GOI reduction) are calculated and used as known coefficients in MVR. This lowers the requirement for many calibration standards and improves analytical accuracy.

Turnkey Calibrations

Ex-works calibrations are available for a variety of materials, including:

Oil industry products using Thermo Scientific™

PetroilQuant™ program or ASTM/ISO methods

Iron, steel and slags

Copper, bronze and brass

Aluminum and alloys

Various oxides through the General Oxide calibration and the Minerals/Ceramics calibration

Cement and clinker, limestone and dolomite, glasses, polymers

Traces in soils and sediments

Total Elemental Analysis- A Unique Advantage

XRF offers a significant advantage over other elemental analysis techniques since it can quantify elemental concentrations without the need for calibration standards.

QuantAS – Scan-Based Standard-Less Software

The user-friendly QuantAS software allows users to quickly determine the concentration levels of unknown liquid or solid samples. In just three minutes, the scans that span 70 elements—from fluorine to uranium—can be completed.

Smoothing, background removal, peak identification, overlap and matrix corrections, semi-quantitative concentration computation, and normalization are all automated techniques that allow for rapid and easy assessment of unknown compounds.

Type standardization is provided to provide the maximum degree of correctness. Four multi-element examples are provided for initial setup and ongoing maintenance.

The factory comes equipped with fully installed and calibrated QuantAS software. Thus, as soon as the ARL PERFORM’X spectrometer is installed at the customer’s site, it is prepared to conduct an insightful examination of unidentified materials.

UniQuant–Industry Leading Standard-Less Analyses

The most potent and advanced Fundamental Parameters algorithms are used in the optional UniQuant software, which is the most powerful standard-less XRF instrument ever made. It is the most suitable choice for evaluating up to 79 elements in liquids and solids in situations where reference samples are either non-existent or only accessible in small amounts, in unusual forms, or with coatings.

The UniQuant software uses 122 carefully selected line positions to determine peak and background intensities. It also calculates the equilibrium of unanalyzed components in the sample, like organic and ultra-light components. In only a few minutes, concentrations with the best detection limits can be achieved by selecting the components and their counting durations.

The manufacturer has properly installed and calibrated the UniQuant software. As a result, the ARL PERFORM’X spectrometer is ready to perform an informative analysis of unidentified samples as soon as it is deployed at the customer’s site. Stable samples are gradually provided for maintenance and setup.
