X-ray spectrophotometers play a crucial role in material analysis, particularly in the detection and quantification of elemental compositions. These instruments are essential for ensuring compliance with environmental regulations such as the Restriction of Hazardous Substances (RoHS) directive. LISUN’s RoHS Testing Equipment, based on Energy Dispersive X-Ray Fluorescence (EDXRF) technology, is a state-of-the-art solution designed to meet these stringent requirements.
The Importance of X-Ray Spectrophotometry in RoHS Compliance
The RoHS directive restricts the use of specific hazardous materials in electrical and electronic equipment. Ensuring compliance with this directive requires precise analysis of the materials used in manufacturing. This is where X-ray spectrophotometers come into play. By utilizing X-ray fluorescence (XRF), these instruments can accurately determine the presence and concentration of elements such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), and polybrominated biphenyls (PBB) and diphenyl ethers (PBDE).
Understanding LISUN’s RoHS Testing Equipment (EDXRF)
LISUN’s RoHS Testing Equipment utilizes EDXRF technology to provide rapid, non-destructive testing of materials. This technology is highly effective for identifying and quantifying the restricted substances outlined in the RoHS directive. The system is designed to be user-friendly, providing accurate results with minimal sample preparation. The EDX-2 series energy scattered X-ray fluorescent spectrometer is realized by analyzing the element characteristic X-ray wavelength and strength of the element emitted by the sample. The elements contained in the sample are determined according to the different elements characteristics of the X -ray wavelength, and the content of the element in the sample can be determined by comparing the strength of the different elemental spectrum.

Key Features:
• High Sensitivity and Accuracy: The EDXRF technology employed in LISUN’s equipment offers high sensitivity, capable of detecting elements in parts per million (ppm). This ensures that even trace amounts of hazardous substances can be identified.
• Non-Destructive Testing: The X-ray spectrophotometer allows for non-destructive analysis, meaning that the samples tested remain intact. This is particularly advantageous for manufacturers who need to preserve samples for further testing or use.
• Fast Analysis: The instrument provides rapid results, enabling manufacturers to quickly assess compliance with RoHS regulations without delaying production schedules.
• User-Friendly Interface: LISUN’s RoHS Testing Equipment is designed with a user-friendly interface, making it accessible even to those with minimal technical expertise. The system’s software guides users through the testing process, ensuring accurate and reliable results.
