[0048] In specific application, the use method and principle are as follows:

[0049] How is the spectrophotometric light path realized: the spectrophotometric light source light path and the spectrophotometric receiving end 31 are on a straight line, the bracket 26 is driven by the stepping motor 24 to move horizontally in the second installation port 3, the detection pool 28 in the four slots 27 is sequentially passed through the spectrophotometric module 14, the light emitted by the light source is transmitted through the detection pool 28, and then the spectrophotometric receiving end 31 receives the light intensity to obtain data.

[0050] How is the Raman light path realized: the Raman detection and the spectrophotometry are the same, the bracket 26 is driven by the stepping motor 24 to move horizontally in the second installation port 3, the detection pool 28 in the four slots 27 is sequentially passed through the Raman light path of the Raman module 5, when a laser beam irradiates on the sample, the photon and the sample molecule have inelastic collision, the energy of the photon is changed, different frequency scattering light is generated, and the Raman spectrum diagram can be obtained.

The second zero position corresponds to the slot 27 close to the spectrometer module 14 side and the spectrometer light path. When performing Raman detection, the bracket 26 first moves to the left to the first zero position. At this time, the sample in the first slot 27 on the left end corresponds to the Raman light path. Then, the bracket 26 is moved to the left one by one, so that each detection pool 28 in the slot 27 is matched with the Raman light path. When performing spectrometer detection, the bracket 26 first moves to the right to the second zero position. At this time, the sample in the first slot 27 on the right end corresponds to the spectrometer light path. Then, the bracket 26 is moved to the right one by one, so that each detection pool 28 in the slot 27 is matched with the spectrometer light path.

[0052] The present example adopts a single light source multi-channel design for Raman and photometric modules with long detection time for a single sample, taking into account the consistency of light sources between different channels and the simultaneous detection of multiple samples in multiple channels, while ensuring detection accuracy and improving detection efficiency. Advantages include:
