XOS Total Lead / Total Arsenic Heavy Metal Series Online Analyzer

Product description
Technical indicators
-Measuring principle:
The Hach XOS total lead / total arsenic online analyzer uses monochromatic wavelength dispersive X-ray fluorescence (MWDXRF) spectroscopic technology to measure lead and arsenic in water.
The analyzer contains a MWDXRF host, an online mobile sample device, touch screen interface, supporting electronic circuit device and computer hardware software system. 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 from a specific wavelength of the X-ray tube, focuses them into a strong monochromatic beam and hits the test sample to excite the inner electrons of lead or arsenic in the sample, and the excited element lead or The X-ray fluorescence of arsenic is intercepted by the collecting DCC mirror and focused on a detector. The intensity detected by the detector (counts per second) is proportional to the lead or arsenic content (mg / kg) contained in the sample. According to this, the content of lead (arsenic) in the sample can be calculated according to the detected intensity using a calibration equation come out.
Compared with the multicolor light excitation used in conventional high-power WDXRF technology, the Hach XOS total lead / total arsenic online analyzer only needs to use a low-power X-ray tube in combination with a DCC mirror to obtain a monochromatic excitation light of sufficient intensity. Monochromatic X-ray excitation significantly reduces background noise, simplifies matrix correction, and increases signal-to-noise ratio.
- typical application:
On-line monitoring of lead and arsenic in water, industrial waste water (such as batteries, electronic waste water), and inlet and outlet of sewage plants
