XRF APPLICATION MODULES

By: Matthew Rayner

1Middle East Workshops April 2012

The biggest challenge with XRF…

• XRF analysis is only as good as the standards used to set up the calibrations

– International standards

– Vendor-supplied standards

– In-house standards

– Custom standards

– “Standardless”

15Middle East Workshops April 2012

Example: Analysis of sub-ppm Ti in polyolephins

16Middle East Workshops April 2012

• Ti is a constituent of the relatively expensive Ziegler-Natta catalyst system, used in the production of polyolephins

• Determining [Ti] is important for quality control and catalyst recovery

Example: Analysis of sub-ppm Ti in polyolephins

17Middle East Workshops April 2012

PANalytical Solutions: Polymers and Plastics

• TOXEL– Similar to ADPOL

– For the analysis of toxic metals, including Cr, Ni, Cu, Zn, As, Br, Cd, Ba, Hg & Pb in polyethylene

26Middle East Workshops April 2012

PANalytical Solutions: “Standardless”

• OMNIAN– Analysis of all sample types without dedicated

calibrations

– Large elemental range

– Market-leading accuracy

27Middle East Workshops April 2012

PANalytical Solutions: “Standardless”

28Middle East Workshops April 2012

PANalytical Solutions: “Standardless”

• 2 Steps in the “Standardless” Approach1. Identify the elements (not required for

conventional approach)

• Advanced algorithms for the determination of background, peak search & match and line overlaps

2. Quantify the elements

• Scan-based measurement for the full elemental composition (default / fast scan)

• Combined with peak measurements for higher precision and lower detection limits

29Middle East Workshops April 2012

PANalytical Solutions: “Standardless”

• Elemental ID & quantification for all sample types– Calibrations set up with a selected range of reference

materials to calibrate instrument response

– Elemental range: O to U

– Adaptive Sample Characterization (ASC) corrects for sample matrix variations and automatically selects the correct calibration for the sample

– Finite Thickness (FT) correction for thin/low density samples

– Fluorescence Volume Geometry (FVG) corrections for liquids and low density samples

– Dark Matrix corrections

– Most sample types, including solids, pressed powders, fused beads, loose powders & liquids
