Problems solved by technology

[0007] The technical problem to be solved by the present invention is that due to the long-term use of the micro-spectrophotometer in the prior art, it is easy to cause a small change in the path length during measurement, and it is difficult to completely correct the small change by manual adjustment. If in order to ensure the experimental results In order to provide a micro spectrophotometer that can perform optical path length correction by itself, it has to restore the factory settings.

Embodiment 2

[0073] figure 2 Shown is a schematic view of the structure of a sampling and measuring device with two jackscrews. The difference between its structure and the structure described in Example 1 is that the sampling and measuring device is also provided with a second jacking wire 2, and the specific setting position is: in the On the above-mentioned measuring platform 4, a second jacking wire 2 is vertically penetrated vertically to the upper measuring platform 4. With respect to the end of the upper measuring platform 4 towards the lower measuring platform 5, the first jacking wire The bottom end of 1 is lower than the bottom end of the second top wire 2.

Abstract

The invention discloses a sampling and measuring device for micro-spectrophotometers, which belongs to the field of micro-spectrophotometers. It includes an upper measurement platform and a lower measurement platform with adjustable distance; the upper measurement platform is provided with a projection fiber seat or a receiving fiber seat, and the lower measurement platform is provided with a receiving fiber seat or a projection fiber seat, and the projection fiber seat and the receiving fiber The seat is aligned up and down and an optical fiber is inserted inside; the upper measurement platform is provided with a first jacking wire, and the position corresponding to the first jacking wire on the lower measuring platform is provided with a lifting seat that can move up and down, and is sleeved on the An electromagnet magnetic cylinder fixed to the lower measuring platform outside the lifting seat; the sampling measuring device also includes a detection unit connected to the receiving optical fiber seat, and the detection unit includes a photoelectric conversion module, a data receiving module, a detection Calculation module, numerical correction module, optical path length selection module and detection data output module. The invention corrects the optical path length by adding a numerical correction module, so that ordinary users can realize accurate measurement without precisely adjusting the optical path length.

Description

Technical field [0001] The invention is the field of optical optical meter, especially involving a micro -optic optical meter. Background technique [0002] The spectrophotia method is one of the commonly used biochemical test methods. It is widely used in the rapid and quantitative testing of samples such as sugar, nucleic acid, enzymes, or protein; the testing instrument of the spectrophotia method is a spectrophotia meter.The dining, but the content of the dine is large, so when conducting a spectacular light detection of the sample inspection sample, on the one hand, it takes a large amount of samples to be checked, resulting in a waste of precious nucleic acids and protein samples. On the other hand, on the other hand, in conductDuring the test of different samples to be checked, it also needs to be cleaned repeatedly to bring a lot of additional work to the experimental work. [0003] The emergence of trace spectrophotic meters effectively solves the above technical problem...
