Instrument introduction

WDX 400 Compact Multi-channel X-Ray Fluorescence Spectrometer features for 10 fixed light diffraction channels, with 10 arbitrary elements defined by the users from Na to U being analyzed simultaneously. The standard ten elements configuration is Na, Mg, Al, Si, S, Cl, K, Ca, Fe, P or Ti（optional）. The instrument is an ideal quality control choice for large and medium-sized enterprises. 
Higher X-ray power, higher measurement precision, more stable measurement data, higher excitation efficiency, lower limit of detection

Performance characteristics

a. reach adequate measurement accuracy with smaller power and equivalent measurement time; 
b. prolonged service life. 
c. fewer failures in high voltage supply, 
d. lower maintenance costs of the overall instrument,
e. no wearing problem of goniometer as fixed channels adopted.
f. Rapid and non-destructive analysis of powder sample and lump sample
g. Fast analyzer of compacted powder, fused beads and lump material
h. Multi-channel digital MCA has greatly improved the measurement efficiency, which benefits not only the instrument debugging and failure diagnosis but also enhances the measurement accuracy and stability.
