Instrument introduction

WDX-200 Small Multi-channel X-Ray Fluorescence Spectrometer features for 10 fixed light diffraction channels, 10 elements being analyzed simultaneously. These 10 elements are arbitrary from Na to U as required by the users. The instrument, an ideal quality control choice for large and medium-sized enterprises, is widely used in cement, steel, powder metallurgy, coal, petroleum, caoline, corhart, environment protection industries and so on.
WDX-200 is a tailor-made high-end analytical instrument for cement industry, meeting requirements of quality control and elemental analysis of the industry. Every technical specification has reached the advanced standard of that of the like international products.

Performance characteristics

Self-developed X-ray Fluorescence analysis system is in seamless connection with DCS system or QCX system built on the OPC SERVER and OPC framework. The configuration can be changed to QCS server. 
All Chinese operating system makes the instrument easy to manipulate. 
The all-spectrum analytical technique is created by us. It traces and corrects every spectrum in real time, which greatly improves the repeatability and stability of quantitative analysis. 
There are two ways of qualitative analysis: empirical coefficient method and theoretical a-coefficient method, among which theoretical a-coefficient method reduces the number of standard sample greatly while retains the accuracy of qualitative analysis.
Analysis data treatment, linear fitting, and various matrices correction
The characteristic value can be calculated according to analysis values. 
Man-machine interaction allows for setting and modifying the parameters. 
Timely output of analysis data and report
Complete self-diagnosis measures
