Description

Technical Field

[0001] The utility model relates to the technical field of sample pretreatment of physical and chemical analysis and environmental monitoring technology, in particular to an ultraviolet digestion device. Background Art

[0002] In the field of physical and chemical analysis and environmental monitoring, it is often necessary to digest samples. For example, in the digestion of water samples, digestion can destroy organic matter, dissolve particulate matter, and oxidize various valence states of the elements to be tested into a single high-valence state or convert them into easily decomposed inorganic compounds. For example, in seawater, elements with a content below 10 μmol·kg-1 are generally called trace elements. They are important components of the seawater chemical system and important parameters for evaluating seawater quality. Monitoring the concentration of trace elements in seawater is an important basis for assessing the quality of the marine environment, protecting the marine environment ecosystem and human health. However, the concentration of trace elements in seawater is extremely low, and some still exist in the form of tiny particles and organic complex colloids. They must be converted into ionic forms through digestion to obtain accurate concentration data. The commonly used method at present is generally to add oxidants and then perform high-temperature and high-pressure digestion. The operation is cumbersome, and the addition of oxidants often introduces non-negligible pollution, affecting the accuracy of the test results.

[0003] Existing ultraviolet digestion devices, such as patent number: CN207181137U discloses an ultraviolet digestion device for water quality detection, including: a first sampling needle, a digester, a plunger pump and a first connecting pipe, wherein the first sampling needle, the digester and the plunger pump are connected in sequence; wherein the digester includes an ultraviolet lamp and a delay mixing ring spirally arranged on the periphery of the ultraviolet lamp with the ultraviolet lamp as the axis, and the two ends of the delay mixing ring are respectively connected to the first sampling needle and the plunger pump through the first connecting pipe. The ultraviolet lamp arrangement structure of the ultraviolet digestion device is single, and it cannot accommodate a large number of samples for digestion at the same time, and thus cannot achieve high-throughput digestion of samples. In addition, the ultraviolet reflectivity of the ultraviolet digestion device is low, and it cannot fully utilize the ultraviolet light for digestion, which reduces the digestion efficiency and affects the results of sample digestion.
