Thermo Scientific UniQuant Software for Standardless XRF Analysis

Thermo Scientific™ UniQuant Software for Standardless XRF Analysis enables the characterization of unknown materials without the need for internal standards or certified reference materials. It delivers semi-quantitative to quantitative results by applying a methodology based on Fundamental Parameters combined with advanced proprietary algorithms for XRF data processing.

The software is designed to handle a wide variety of sample types, including multi-element solids, pressed powders with or without binders, small samples on supporting films, liquids, and aerosol filters. This flexibility allows for reliable elemental identification and composition analysis within minutes.

• Sample preparation is typically minimal or not required. UniQuant can analyze up to 79 elements, from boron to americium, including their oxide forms. 
• For each element, the software reports the standard deviation (sigma) in ppm, along with results expressed in weight percent and an estimated error.
• To ensure accuracy, the software applies corrections for background, spectral interferences, line overlaps, matrix effects, and selected physical influences. 
• High-power measurements are generally completed in less than 14 minutes, while samples belonging to known material groups can be analyzed in as little as 5 minutes.
• For applications requiring enhanced accuracy, specially calibrated datasets can be used.

Thin Layer Samples

For mono-layer samples, UniQuant can simultaneously determine layer composition and sample mass, including the associated standard deviation. If the substrate contains elements present in the layer, their influence is automatically taken into account.

Interactivity

The user interface is optimized to minimize the number of steps required for operation. It also enables rapid adjustment of analytical assumptions, such as switching between sulfide and oxide models for unknown sample evaluation.

Batch Modes

Batch processing is supported for both calibration (set-up) samples and groups of unknown samples. Samples can be organized and tagged within directories, allowing the analysis process to be initiated efficiently.
