[0018] Nowadays, most water quality is tested by spectrometry and mass spectrometry respectively. When the same batch of water is tested by a spectrometer, the light may affect the content of certain substances in the water, resulting in inaccurate results of the subsequent mass spectrometry test.

[0019] like Figure 1-Figure 3 As shown, the present embodiment provides a high-precision detector for harmful substances in water quality based on spectroscopy and mass spectrometry technology, including a detection component 100, the detection component 100 includes a detector 101 and a diversion component 110, the diversion component 110 is arranged on one side of the detector 101, considering that the water source sample to be detected is diverted for detection, therefore, the diversion component 110 includes a diversion block 112 and two detection chambers 113, the diversion block 112 is used to divert the water flow and discharge it to the detection chamber 113, and the detection port of the detection chamber 113 is connected to the detector 101.

[0020] The improvement of this embodiment lies in that a diversion component 110 is set in the detection component 100, and the diversion component 110 is used to divert and flow the poured water source, so that the detector 101 can perform synchronous spectral and mass spectrometry detection on the same batch of water source samples, thereby avoiding the situation in which, in step-by-step detection, some substances contained in the water source sample will be affected by the detection mechanism after one of the tests, resulting in changes in the content of some internal substances, thereby affecting the subsequent detection.

[0021] In order to facilitate the discharge of the water source after detection, the second embodiment of the utility model is shown.

[0022] The diversion component 110 includes an inlet 111, and a diversion block 112 is fixed below the inlet 111, so that after the water source falls, the water source is diverted by the diversion block 112 and introduced into the detection chamber 113, a guide plate 114 is provided at the bottom of the detection chamber 113, and a switch pump 115 is provided on one side of the detection chamber 113. The water source is drained and collected to the switch pump 115 through the guide plate 114, so that the detection water source sample in the detection chamber 113 is conveniently discharged from the detection chamber 113 through the switch pump 115. A drainage chamber 116 is provided on one side of the switch pump 115, and a collecting chamber 117 is provided on one side of the drainage chamber 116. The drainage chamber 116 is communicated with the collecting chamber 117, and the detection water source sample discharged by the switch pump 115 is introduced into the collecting chamber 117 through the drainage chamber 116 and collected. A discharge port 118 is provided on one side of the collecting chamber 117, and the detection water source sample is discharged from the device through the discharge port 118.

[0023] In summary, the working principle of this solution is as follows:

[0024] The water source sample to be tested is poured into the feed port 111. When the water source sample to be tested contacts the diverter block 112 below the feed port 111, the water source sample to be tested is diverted and enters the detection chambers 113 on both sides of the diverter block 112 respectively. The detector 101 is started, and the detector 101 simultaneously performs spectral testing and mass spectrometry testing on the water source sample to be tested in the detection chamber 113. When the detection is completed, the guide plate 114 at the bottom of the detection chamber 113 collects the tested water source sample to the switch pump 115, and the switch of the switch pump 115 is rotated to discharge the water source sample in the detection chamber 113 to the drainage chamber 116, and the water source sample discharged from the detection chamber 113 is collected into the collecting chamber 117 through the drainage chamber 116, and the tested water source sample is discharged into the device through the discharge port 118 on one side of the collecting chamber 117.
