Introduction Standardless analysis

Complete composition of most types of unknownmaterials can be quantified with a single calibrationprogram Calibration set up with a selected range of reference

materials to calibrate the instrument response

Covers all common elements that can be measured by XRF:by default O-U O-UXRF

Makes use of (a form of) Fundamental Parameter (FP)

calculations to correct for all sample-matrix specificproperties

Handles most types of samples, including solids, pressedpowders, fused beads, loose powders and liquids

,


5/32


Introduction Standardless analysis

How is a quantitative result obtained?

Two steps: 1.

Determine which elements are present in the

sample

2.

Calculate the concentration of each element that is

present. This gives the total sample composition

NOTE: A conventional analysis only has to deal withstep 2, because the elements of interest are alreadyknown.

Omnian advantages

The right result every time Easy to use Problem solving power foryour analytical challenges


7/32


The right result every time The basis of a good result is toobtain accurate net intensities

Having advanced algorithms forthe determination of background,peak search & match and line-

overlaps

Using a scan-based measurementprogram, for a comprehensivepicture of the sample

but can be combined with peakmeasurements for higher precision andlower detection limits for key elements


8/32


The right result every time By using scans a comprehensive picture of thesample is given:

Allowing both qualitative and quantitative

analysis

Quick visual screening or full quantification

Providing an accurate background profile

Superior to the estimations obtained from fixedbackground positions

Providing a view of all peaks and backgrounds across theperiodic table

Reduces the chance of incorrect element identification

Problem solving power R&D analysis tool

For analyses of all types of samples For detailed investigation of results

Failure analysis

To identify steps in a process where things might gowrong, e.g by analyzing:

A particular bolt or screw A powder that was found in an instrument; itmight come from components wear


16/32


Problem solving power Comparative analysis For comparison of different samples

To distinguish samples on matrix differences (e.g. stainless vs.low-alloy steel or PE vs. PVC polymer) PE PVC

Helps to monitor and steer your process by comparingsamples from different batches

Advanced technology Finite thickness characteristics High-energy lines will have a larger

penetration

depth in the sample than low

energy lines

The penetration depth in light matrices is

larger than in heavy matrices

FP corrects in case the sample is not infinite

thick for all measured energies

Irradiated and detected

Not irradiated and detected

Advanced technology Fluorescence Volume Geometry (FVG)

The irradiated area of a light-matrixsample is not only determined by thepenetration depth

It is also determined by the geometry ofthe optical path

FP corrects for the FVG effect

It takes into account the real geometry ofthe irradiated area, which is far morecomplex than the wedge-shape as drawnin the picture

Omnians advanced FP algorithmsdeal with:

Advanced technology

FP calculates the Dark Matrix compounds from the measuredCompton-scattered tube intensity

This Compton intensity is reversely proportional to the density of thesample

A heavy

matrix (e.g. Copper) will have low Compton scatter whereas a light

matrix (e.g. B4

C) will have a high Compton scatter:B4

C


23/32


Example Calculation of Dark Matrix compound

Example: B in glass

This clearly indicates that using the

Compton intensity gives a far moreaccurate result

Example: LOI in Limestone

There is not much difference between

calculating LOI as balance or from theCompton line, but: this comparisongives a clear indication of thecorrectness of the results!

FastScan analysis

FastScan

analysis is a unique feature of Omnian

coupled with

an Axios

spectrometer OmnianAxios

For a quick determination of all majors and minors

For samples that are likely to be damaged by X-rays

covers the complete periodic table 1

Combining FastScan

with selected peak

measurements, the accuracy for critical or low-

concentration elements canbe

increased
