preparation example Construction
[0043] The preparation method of the magnetic immunochromatography standard card of one embodiment of the present invention comprises the following steps:
[0044] (1) prepare stuck case;
[0045] (2) Select wires of specific material, diameter and length according to the above requirements;
[0046] (3) Fix the metal wire on the clamping shell to prepare a standard card;
[0047] (4) Use a standard instrument to detect and determine the standard magnetic signal detection interval of the standard card.
[0048] The magnetic signal reading accuracy detection method of the magnetic immunochromatography instrument according to one embodiment of the present invention comprises the following steps:
[0049] (1) Put the above-mentioned standard card for magnetic immunochromatography in a magnetic immunochromatography instrument for magnetic signal detection, and obtain the detection signal result.
[0050] (2) Compare the detection signal result with the standard magnetic signal ...
Embodiment 1
[0057] nickel wire
[0058] The structure of standard card 1-1 is as follows figure 1 As shown, the metal wire is nickel wire (L=4mm, d=0.05mm);
[0059] The structure of standard card 1-2 is as follows figure 1 As shown, the metal wire is nickel wire (L=3mm, d=0.05mm);
[0060] The structure of standard card 1-3 is as follows figure 1 As shown, the metal wire is nickel wire (L=2mm, d=0.05mm);
[0061] The test results are shown in Table 1.
[0062] Table 1: Table of test results (magnetic signal values) of standard card 1-1 to standard card 1-3
[0063]
[0064] It can be seen from Table 1 that standard card 1-1 to standard card 1-3 all have stable magnetic signal values, and the length of the metal wire has a certain influence on the magnetic signal value, indicating that the magnetic signal range of the instrument under test can be Choose the appropriate length of wire.
Embodiment 2
[0066] Aluminum wire
[0067] The structure of the standard card 2-1 is as follows figure 1 As shown, the metal wire is aluminum wire (L=4mm, d=0.1m), and the test results are shown in Table 2 below.
[0068] Table 2: Table of test results (magnetic signal values) of standard card 2-1
[0069]
[0070] It can be seen from Table 2 that the standard card 2-1 has a relatively stable magnetic signal value every time it is detected.
