A new application brief explains how a new generation of portable energy dispersive X-ray fluorescence (ED-XRF) instruments can provide performance comparable to laboratory-based systems and offer the flexibility to be easily moved to various process points to provide high-accuracy Quality Assurance (QA)/Quality Control (QC) for producers of steel or aluminum sheets.
The brief, “At-Line Analysis of Coat Weight on Steel and Aluminum Sheets using ED-XRF Spectroscopy at the Process Line,” is available to download这里来自高级仪器的领先制造商Spectro Analytical Instruments。
Steel and aluminum sheet producers often coat their products to protect them from rust or corrosion or to achieve a variety of objectives. The sheets go through a number of chemical processes to convert the steel or aluminum into the coating material. The consistency of coating thickness — commonly referred to as “coat weight” — is vital to successful production quality and requires advanced analytical techniques.
根据基材和客户需求，可能需要进行分析仪器来检测和测量各种涂层材料的厚度。亚博网站下载
X-ray fluorescence (XRF) spectroscopy is an excellent technology for coat-weight analysis and can be performed with a variety of instruments, ranging from handheld systems to laboratory-based wavelength-dispersive X-ray spectroscopy (WD-XRF) instruments.
实验室仪器很昂贵，可能会延迟流程时间表，因为必须从生产线到实验室采集样品。手持XRF系统很受欢迎，但具有许多实用和分析的缺点。
现在，新的便携式ED-XRF仪器（例如Spectroscout Portable Analyzer）具有出色的分析范围和精度，表现出非常低的检测极限。已显示使用该仪器在线可提供可靠的涂料重量测量，包括铁，锌，磷酸锰，锆，铬，铬和钛在内的各种涂料材料。亚博网站下载
