Background

When the near infrared spectrometer is used for carrying out spectrum analysis on the traditional Chinese medicinal materials, the traditional Chinese medicinal materials have different forms, and the sample carrying container equipped with the current near infrared spectrometer has fixed forms, so the universality is poor. For example, when detecting dendrobium huoshanense in a spiral hollowed-out form, the dendrobium huoshanense is easy to freely move in a sample bearing container, and near infrared detection light is easy to escape from a hollowed-out area; a large measurement error is introduced.

When the near infrared spectrometer detection accessory is used, a worker moves the first Dan Yingmin and the second quartz plate oppositely or back to change the volume of the sample cell, so that the free movement of an irregular sample in the sample cell can be prevented better; meanwhile, the arrangement of the reflecting plate can avoid the escape of near infrared detection light rays to the greatest extent, so that measurement errors can be reduced better.

Preferably, the second quartz capsule is adapted to slidingly engage the first quartz capsule. Therefore, the shape of the sample cell is preferably adjusted so as to fix samples in different shapes.

Preferably, a guiding inclined plane is arranged at the position, corresponding to the outer side wall of the second quartz plate, of the inner end face of the second quartz plate, and the guiding inclined plane gradually inclines towards the middle of the second Dan Yingmin from the position far away from the inner end face of the second Dan Yingmin to the position far away from the inner end face of the second Dan Yingmin. So that the operation is convenient.

Preferably, a rubber gasket is arranged at the inner side wall of the first quartz groove, and the inner side wall of the rubber gasket is used for being matched with the outer side wall of the second Dan Yingmin to form a positioning part. Thus facilitating the retention of the sample cell in a predetermined configuration.

Preferably, the rubber gasket extends from the bottom wall of the first quartz groove to the opening of the first quartz groove. Therefore, the structure is simple and easy to realize.

Preferably, the rubber gaskets are circumferentially spaced along the first quartz groove. So that a viewing window can be preferably provided.

Preferably, the reflective plate is provided at an outer end portion of the second Dan Yingmin. Therefore, the device is easy to realize and has a simple structure.

The invention also discloses near infrared detection equipment which comprises any one of the near infrared spectrometer detection accessories.
