Halogen-Free Analysis Product Evaluation

EDX

Analysis of Halogen Elements (Chlorine) Using an EDX Spectrometer
Due to its ability to analyze solids, powders, liquids, and other samples quickly, easily, and non-destructively, X-ray fluorescence
analysis has been widely used for screening elements regulated by RoHS and ELV directives. More recently, the electrical/ Plastic Materials Evaluation of
electronic industries have been promoting the elimination of halogen elements, such as BR and Cl, from their products, in
addition to the five elements subject to the RoHS directive. In this example, Cl was analyzed in plastic. Raw Materials Evaluation of

Cl Spectra Calibration Curve for Cl Kα Product Evaluation

The calibration curve was created using a standard sample prepared by adding Cl to Analytical Conditions
polyethylene (PE) plastic.
Instrument: EDX-720 Product Information
Spectrum: Cl Kα
Features of the EDX Series Tube voltage: 15 kV
Tube current: Automatic
The primary filter included standard for Cl allows easily measuring Cl with high Measurement time: 100 sec
sensitivity. Also, attaching a vacuum measurement unit (option) allows analyzing Cl Optimal filter used
with even higher sensitivity.

Analysis
The Cl content in a plastic plate specimen and plastic parts was measured. In addition, shape correction based on the
background internal standard correction function was used to correct for the thickness, shape, and size of samples. Background
internal standard correction corrects quantitation values based on the ratio between continuous X-rays from the X-ray tube or
characteristic X-rays from the target and scattered rays.
