HMA-TMN Total Manganese Heavy Metal Analyzer

-Measuring principle:

 

The instrument is detected by colorimetric spectrophotometry. The sample is first added with digestion reagents, and then pumped to the high-temperature digestion unit for high-temperature digestion. The total manganese in the sample is digested into divalent manganese ions. The divalent manganese ion of the sample reacts with formaldehyde oxime in a slightly alkaline solution and forms a brown colored complex. The spectrophotometric measurement is performed at a wavelength of 470 nm. According to the initial color of the sample and the color change after adding the developer Different degrees to determine the concentration of the analyzed sample.
