Featuring advanced third generation energy dispersive X-ray fluorescence (EDXRF) technology, the Rigaku NEX LS represents the next evolution of scanning multi-element process coatings analyzers for web or coil applications.

Energy dispersive X-ray fluorescence (EDXRF)

To deliver superior analytical performance and reliability, the EDXRF measuring head assembly was derived from the established Rigaku NEX Series high-resolution benchtop instrumentation. With their proven technology, the Rigaku NEX LS delivers rapid, non-destructive, multi-element analyses — for coat weight, coating thickness and/or composition — for elements from aluminium (₁₃Al) through uranium (₉₂U).

Coat weight profiling—a clear visual representation of your process

NEX LS software is user-friendly and provides a clear visual representation of your process so that you can make immediate quality control decisions. A flow bar method builder helps you input basic information about your application, and the advanced NEX LS software helps you achieve continuous process control from the beginning to the end of the roll.

Roll reports include machine direction, cross direction, and full lane average graphs—measurement value, date, time, length, product name, and other information. You can customize reports, export them as PDF or CSV, and store copies on USB or a network using industry-standard communications protocols.

NEX LS allows you to monitor your process in real-time—from start to finish.

Coat weight analysis or loading analysis—solve challenges in real-time

Controlling coating thickness or composition is vital to meeting end-use specifications for the release, metal finishing, and automotive industries. If coatings or composition are not in spec throughout the process, this could lead to product rejection or failure. NEX LS helps solve the challenges of coating and converting processes in real-time.

Silicone coaters can achieve a targeted laydown to ensure release properties or barriers are not compromised. If too little or too much silicone is applied, this can change the product’s characteristics, resulting in product rejection and reduced profitability. With an increased demand for fuel cell and battery-powered electric vehicles, profiling the substrate or loading is crucial in manufacturing. NEX LS provides real-time results throughout these processes and is an excellent system for new product development.

NEX LS is an excellent choice for:

• Silicone release coaters
• Converters—silicone on plastic or paper
• Vacuum-formed plastics—denesting silicone coatings
• Specialty films—moisture and air barriers
• Conversion coatings
• Fuel cell loadings
• Metalized plastic
• Top coatings on metal coil
