1NCG-1 Cold Atomic Absorption Mercury Analyzerworking principle:

The unique properties of mercury and its compounds have been widely used in scientific research and production, but they have also caused environmental pollution and posed a threat to organisms. Therefore, the monitoring of mercury has received great attention from the country, and the analysis methods for trace mercury are constantly improving. The requirements for mercury measuring instruments are also increasing. Therefore, the mercury measuring instrument developed by our company is manufactured on the basis of the original product, which greatly improves drift and noise, enhances sensitivity and accuracy, and has digital retention function. Based on the fact that elemental mercury can evaporate into mercury vapor at room temperature without heating, it has a strong absorption effect on ultraviolet light with a wavelength of 253.7nm. Within a certain range, the concentration of mercury is proportional to the absorption value, which conforms to Beer's law.
