1、 Purpose and principle:

Mercury element analyzer(Hereinafter referred to as the instrument)It can conveniently and quickly determine the mercury in coal samples that have been processed and converted into solutions, as well as the low concentration mercury in liquid samples.

Mercury atomic vapor has a wavelength of253.7nmUltraviolet light has a strong absorption effect, and within a certain range, the relationship between its absorption value and the concentration of mercury atomic vapor follows Beer's law. The instrument is designed and manufactured based on this principle. The mercury ions contained in the sample solution in the reduction bottle are reduced to metallic mercury by stannous chloride. Under the action of the circulation pump, the metal Mercury vaporizes and is loaded into the absorption tank. The instrument measures its absorption value and the internal computer system calculates it to display or print the concentration of mercury in the sample.

The instrument is also configuredRS-232CSerial interface. The mercury analyzer data processing software used. This software can be installed on a computerWindowsOn the operating system, the computer can receive mercury measurement signals from the instrument and calculate the concentration of mercury based on the standard curve and other set parameters. Measurement data can be stored in the form of files Inside the computer, it also has the function of retrieving measurement data files.
