Multi-channel rotary type Raman spectroscopy detection sample pool device and detecting method thereof

Abstract

The invention discloses a multi-channel rotary type Raman spectroscopy detection sample pool device which comprises a rotary sample table for containing a sample pool, a linear movement mechanism for controlling the sample pool at a position in the XY plane, a rotary movement mechanism, a multi-position valve control mechanism and a Raman spectrograph probe. The rotary sample table is arranged on the rotary movement mechanism in a rotatable mode. The rotary movement mechanism is used for controlling the positions of the sample pool and the Raman spectrograph probe. A water sample to be tested is controlled by the multi-position valve control mechanism to enter the sample pool on the rotary sample table, the position of the sample pool is adjusted through the linear movement mechanism and the rotary movement mechanism, optical detection is conducted through the Raman spectrograph probe, and optical signals are sent into a spectrograph upper computer so that real-time analysis can be achieved. By means of the sample pool, by adjusting rotary movement and horizontal displacement, the water sample to be tested can be accurately focused, and detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of Raman spectrum detection instruments, in particular to a multi-channel rotary sample cell device based on Raman spectrum detection and a detection method thereof. Background technique [0002] In recent years, with the acceleration of industrialization and urbanization in my country, the demand for water resources has also increased significantly; at the same time, a large amount of industrial wastewater and urban domestic sewage are directly discharged into rivers, lakes, seas and soil, making surface water and groundwater water quality worse. It is deteriorating day by day, and the water pollution situation is becoming more and more severe, which greatly restricts the development of the national economy and endangers the health of the people. Water quality monitoring is an important means to reflect the quality of the water environment and the status quo of pollution sources in a timely, accurate and com...
