Embodiment

[0010] Example: refer to figure 1 , a paper tape sampling spectrophotometer, including a spectrophotometer body containing a cuvette 8 and a light detector 9, wherein: the body is provided with a reel 2 that can wrap the paper tape 1; The paper tape 1 is pulled to the traction wheel 4 near the surface of the punching knife seat 6; the punching knife seat 6 has a punching knife hole 61, and a punching knife 5 is arranged above the punching knife hole 61; a mixer is arranged below the punching knife seat 6 7; The mixer 7 is provided with a sample valve 71, and the end of the sample valve 71 is located near the cuvette 8. Paper tape 1 with chemical reagent, soaked on paper tape 1 and wrapped around 2 after drying. After the paper tape 1 is drawn to the punching knife seat 6 , the punching knife 5 cuts the paper tape 1 and forms a paper tape piece 11 with the same shape as the punching knife hole 61 . The paper tape piece 11 falls into the mixer 7, is mixed with the solution to ...

Abstract

The invention discloses a paper tape type sample injection spectrophotometer which comprises a spectrophotometer body comprising a cuvette and an optical detector, wherein a roller wheel which is wound by a paper tape is arranged in the body; a traction wheel capable of clamping and pulling the paper tape to reach a position nearby the surface of a stamping knife seat is arranged in the body; a stamping knife hole is formed in the stamping knife seat; a stamping knife is arranged above the stamping knife hole; a mixer is arranged below the stamping knife seat; a sample valve is arranged on the mixer; and the tail end of the sample valve is positioned nearby the cuvette. The paper tape is provided with chemical reagents, and is soaked and dried, and then the soaked and dried paper tape is wound on sample. After the paper tape is pulled to the stamping knife seat, the paper tape is cut by the stamping knife to form a paper tape piece which is consistent with the stamping knife hole in shape. The spectrophotometer has the advantages of suitableness for automatic sample injection, convenience in reagent carrying, simplicity in preservation and slight manual intervention in the detection process.

Description

technical field [0001] The present invention relates to a spectrophotometer device, in particular to a paper-tape sampling spectrophotometer. Background technique [0002] In the existing spectrophotometer, the spectrophotometer is usually used as the detection instrument for the sample after the sample is made. Do the test after the chamber cover. There are usually four cuvettes for storing samples and standard solutions in the sample chamber of the spectrophotometer. Due to different raw materials and processing techniques, there are errors in transmittance in the production of the cuvettes. The cuvettes must be calibrated in advance. The error between the test samples can be started. When pushing and pulling the push rod of the cuvette rack in the sample room, due to human error and unclear positioning of the instrument, the cuvette rack will not fall in place and cause light blocking and test errors will occur; after the test is completed, all used All cuvettes are ta...
