Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] refer to figure 1 As shown, it is a schematic flow chart of a method for free wavelength selection in an embodiment of the present invention, including:

[0026] Step 101, select the wavelength output scheme of the biochemical analyzer according to the requirements, the specific implementation process is as follows:

[0027] In this embodiment, the grating P0580-1 produced by Shimadzu Corporation is used. The working range of the grating is 340nm-850nm, which is just the working range of the wavelength used by the biochemical analyzer. The distance between two adjacent wavelengths on the photodiode array surface is about 0.06mm / nm, and the photodiode array S4114 of Hamamatsu Company is used, and the distance betwe...

Abstract

The invention discloses a free selection method for a wavelength, which comprises the following steps: determining two diodes corresponding to the wavelengths falling between the two diodes; and short-circuiting anodes and cathodes of the two diodes corresponding to the wavelengths falling between the two diodes according to a wavelength arrangement solution. The free selection method of the wavelength can support and implement any wavelength solution.

Description

technical field [0001] The invention relates to the technical field of biochemical analyzers, in particular to a method for free selection of wavelengths. Background technique [0002] In the biochemical analyzer system, there is a wavelength scheme, which is essentially a collection of all wavelengths that the instrument can provide. In general, the wavelength schemes of different manufacturers are not the same, not only the number of wavelengths is different, but also the corresponding wavelengths are not the same when the number of wavelengths is the same. Generally, some wavelengths will differ by 5-10nm or more. [0003] From the clinical point of view of the biochemical analyzer, for the test of a specific item, the main wavelength of the test it uses is fixed. This wavelength is the absorption peak of the absorption spectrum of the reaction solution of the item. If this wavelength is used, the light The absorption is the largest, and the test accuracy is the highest;...
