COATING THICKNESS MEASUREMENT

Oxford Instruments offer a range of coating thickness analysers, gauges and SEM based systems for measuring a broad range of coating thickness on almost any metal substrate, whether ferrous or non-ferrous.

XRF-BASED ANALYSERS

X-ray Fluorescence (XRF) instruments work by exposing a sample to be measured to a beam of primary X-rays. The atoms of the sample absorb energy from the X-rays, become temporarily excited and then emit secondary X-rays. Each chemical element emits X-rays at a unique energy. By measuring the intensity and characteristic energy of the emitted X-rays, an XRF analyser can provide qualitative and quantitative analysis regarding the thickness and composition of the material being tested.

Benefits of analysis by X-ray fluorescence:

• Minimal or no sample preparation
• Non-destructive analysis
• Wide range of element determination
• Analysis of solids and solutions
• Rapid analysis: results in seconds
• Qualitative, semi-quantitative and full quantitative analysis
• Easy to use with only minimal training

OXFORD INSTRUMENTS XRF COATING THICKNESS ANALYSERS PROVIDE
A COMBINATION OF COATING THICKNESS, SIMPLE MATERIAL AND LIQUID
ANALYSIS IN ONE INSTRUMENT

Maxxi-6

The Oxford Instruments Maxxi-6 is the latest XRF based coating thickness analyser from Roentgenanalytik (now an Oxford Instruments company). The Maxxi-6 is capable of analysing a wide range of elements: from P15* to U92 in the periodic table – allowing the measurement of almost every type of metallic coating. Its modular upgrade path offers potential for changes in requirements protecting your investment and minimising long-term ownership costs.

(* Measurement of P is concentration dependant)

X-STRATA 920 MICRO SPOT XRF

The Oxford Instruments X-Strata is a cost-effective, rapid and reliable XRF for coating thickness measurement and materials analysis. It offers a wide range of element determination, from Ti22 to U92.

Both the MAXXI 6 and X-Strata 920 comply with the following international coating thickness test methods using the XRF technique:

• ASTM B568: Standard test method for measurement of coating thickness by X-ray spectrometry
• ISO 3497: Metallic coatings – measurement of coating thickness – X-ray spectrometric methods

Applications include:

AZTEC LAYERPROBE MULTILAYER THIN FILM ANALYSIS SOFTWARE

AZtec LayerProbe is a non-destructive, high-resolution solution for layer thickness and composition characterisation in a Scanning Electron Microscope (SEM / FIBSEM)

LayerProbe uses robust quantitative analysis routines available in AZtec and integrates them with powerful thin film analysis engine for reliable results. The software also includes a tool to predict solubility and to advise on optimum analysis conditions as well as a simulation tool to accurately simulate X-Ray spectra from layered specimens.

• Non-destructive analysis with minimal sample preparation necessary
• Predicts solvability and optimum experimental parameters to enable reliable, precise measurements
• Analysis of layers down to 1nm thickness*
• Total structure thickness up to several microns possible*
• Includes simulation tool to generate simulated X-ray spectra of thin film structures

*Precise limits are sample dependent and can be determined using the Solvability Tool supplied with the software
