Product features

Highly reliable and stable instrument design: Modularized design shall be made for thermostatic chamber, X-ray tube cooling system, gas flow density and flow stability control system, vacuum control system, beam splitting system, detector, etc., so as to make the entire instrument easy for maintenance and run stably.

Thermostatic chamber: Intelligent balance system is adopted for the design of thermostatic chamber and temperature control system in the instrument, thus making the maximum temperature fluctuation of thermostatic chamber less than 0.1 °C.

X-ray tube cooling system: With intelligent temperature control system, the X-ray tube cooling oil temperature fluctuation is less than 1°C, thus making the temperature of main heat source in thermostatic chamber - X-ray tube protective sleeve stable, which can not only create the condition to reduce the temperature fluctuation in thermostatic chamber, but also reduce expansion and contraction of analyzing crystals.

Gas flow density and flow stability control system: Intelligent gas flow density and flow stability control system is adopted to ensure the stability and reliability of the counts of detector and really reflect the actual proportion change of reactive elements.

Vacuum control system: Modularized vacuum system makes it easy for maintenance and replacement. Thanks to the highly efficient vacuum system, the vacuum pre-pumping time becomes shorter, vacuum degree is high and switching-over is convenient.

Beam splitting system: With highly efficient optical path and short optical path, original light path parts are used, thus effectively shortening the optical path length of X-ray fluorescence and greatly improving the collection efficiency of X-ray fluorescence in every element path.

Detector: Different detectors (flow proportional detectors, closed proportional detectors and scintillation detectors) are configured according to the elements to be measured. Among them, flow proportional detectors adopt miniaturized counter tube, high-voltage circuit and signal amplification circuit for modularization, so as to make detector assembly directly connect with high-speed sampling circuit, thus significantly improving the anti-jamming capability of detection circuit; at the same time, the number of connecting cables and connectors has been reduced greatly, so as to improve the reliability of instrument.

Humanized software workstations: By adopting man-machine interaction software interface and modular operating buttons, different operating authorities and diversified output reports can be set, allowing the users to operate more flexibly, conveniently and intuitively. Meanwhile, the software has integrated the commonly used DCS system communication protocols like TCP/IP, OPC, ModBus, RS232/485, etc., thus making it possible for the instrument to exchange data with the control center or PLC of the batching system in the factory, that is to say, both analytical data and matching data can be transmitted to the batching system to realize online data analysis and online quality monitoring.
