State-of-the-Art Components for Highest Flexibility

The ARL PERFORM’X spectrometer now features a 6^th generation goniometer that is entirely digitally mastered, allowing for faster and more accurate measurements.

The goniometer can be set up to do quantitative or qualitative analysis on certain elements, which involves scanning the X-Ray spectrum to find elements in a given sample. With up to nine analytical crystals and four collimators, this cutting-edge compact goniometer offers analysts a greater variety of applications. The extremely small goniometer technology increases elemental signal count rates by up to 25%. At high count rates, improved detector linearity yields superior counting statistics.

Adding seven primary X-Ray beam filters also broadens the analytical range, minimizing interference from X-Ray tube emission lines on some elements and significantly enhancing peak-to-background ratios for most elements.

The number of sample types that can be studied is increased by additional optional features, such as the 4-position programmed aperture changer. There is a 29 mm aperture by default, and three other apertures with the following sizes are selectable: 0.5, 1.5, 5, 10, 15, 20, 25, and 35 mm to facilitate the examination of both small and big samples.

The X-Ray tube’s LoVap filament technology, which operates at a lower temperature and eliminates drift caused by tungsten vapor plating on the beryllium tube window, offers long-term stability. A closer coupling between the anode and sample is also made possible by developing the X-Ray tube cone. For every element in the periodic table, this results in increased sensitivity and decreased detection limits.

Automatic Sample Loading Creates Productivity

The ARL PERFORM’X spectrometer could be located right above the sample changer. It can handle a maximum capacity configuration of 112 samples for unattended and overnight analysis, accommodating various sample sizes. Any urgent sample may be put on the designated “urgent” spot at any moment to be processed first.

Without the requirement for cassettes, a series of homogeneous-sized and shaped samples (such as polymer discs, pressed pellets, fusion beads, etc.) can be put directly into trays.

For liquid analysis, specialized cassettes are utilized to ensure that liquids are never loaded under vacuum.

An automated sample preparation equipment can be connected to for continuous online process monitoring in the unattended mode. The ARL PERFORM’X spectrometer and the automated press, mill, or fusion machine will be connected by a simple transport belt.The spectrometer and the preparation equipment can interact, thanks to the OXSAS/OEM software option.

Fast and Accurate Analysis

Fast Qualitative Analysis

Step scanning can precisely define peaks with a precision of 0.001°. Continuous digital scanning captures spectra up to 500° per minute, making it ideal for rapid qualitative analysis. Peaks are automatically identified as representing the components present.

Accuracy Made Easy

The online Analytical Assistant allows for rapid and accurate definition of analytical programs and calibrations. The multi-variable regression (MVR) software is used to generate calibration curves. Correction models decrease the effect of interfering components in multi-component matrices, improving analytical accuracy. 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

Comprehensive Lachance (COLA) with 3 term alphas is utilized with NBSGSC fundamental parameters software, replicating analytical calibrations for homogenous materials.Inter-element correction factors (theoretical alphas with matrix and LOI/GOI reduction) are generated and utilized as known coefficients in MVR. This reduces the need for several calibration standards and enhances analytical accuracy.

Turnkey Calibrations

Ex-works calibrations can be provided for numerous materials, including:

Oil industry products using Thermo Scientific™

PetroilQuant™ program or ASTM/ISO methods

Total Elemental Analysis- A Unique Advantage

XRF has a distinct advantage over other elemental analysis techniques as it can measure elemental concentrations without calibration standards.

QuantAS – Scan-Based Standard-Less Software

Unknown liquid or solid sample concentration levels can be rapidly ascertained with the help of the user-friendly QuantAS software. In about three minutes, the scans that span 70 elements—from fluorine to uranium—can be completed.

The automatic processes of smoothing, background removal, peak identification, overlap and matrix corrections, semi-quantitative concentration computation, and normalization enable quick and simple measurement of unknown materials. Type standardization is offered for the highest level of accuracy. For setup and upkeep over time, four multielement examples are included.

From the manufacturer, the optional QuantAS software is installed and calibrated to perfection. Due to this, the ARL PERFORM’X spectrometer is prepared to analyze unknown samples meaningfully as soon as it is installed at the customer’s site.
