Hach XOS online monitoring instrument for total lead/total arsenic heavy metals

-Hach XOS online monitoring instrument for total lead/total arsenic heavy metalsMeasurement principle:

Hach XOS total lead/total arsenic heavy metal online monitoring instrument uses monochromatic wavelength dispersive X-ray fluorescence (MWDXRF) spectroscopy technology to measure lead and arsenic elements in water.

This heavy metal online monitoring device contains a MWDXRF host, an online flowing sample device, a touch screen interface, supporting electronic circuit devices, and computer hardware and software systems.

An X-ray tube produces a continuous X-ray spectrum, with a maximum power of 50 W (voltage 50 kV and current 1 mA). The excitation DCC mirror intercepts X-rays of a specific wavelength from the X-ray tube, focuses them into a strong monochromatic beam, and hits the test sample to excite the inner layer electrons of lead or arsenic elements in the sample. The X-ray fluorescence radiation of the excited element lead or arsenic is collected by the DCC mirror and focused onto a detector.

The intensity detected by the detector (counts per second) is directly proportional to the lead or arsenic content (mg/kg) in the sample. Based on this, the lead (arsenic) content in the sample can be calculated using a calibration equation based on the detected intensity.

Compared with the multi-color light excitation used in conventional high-power WDXRF technology, the Hach XOS total lead/total arsenic heavy metal online monitor only requires the use of low-power X-ray tubes and DCC mirrors to obtain sufficient intensity of monochromatic excitation light. Monochromatic X-ray excitation significantly reduces background noise, simplifies substrate correction, and increases signal-to-noise ratio.

-Typical applications:

The XOS total lead/total arsenic heavy metal online monitoring instrument is suitable for online monitoring of lead and arsenic in water, industrial wastewater (such as battery and electronic wastewater), and sewage plant inlet and outlet
