Embodiment 1

[0028] Please refer to Figure 1 to Figure 6 , Embodiment 1 of the present invention is:

[0029] A viscosity detection target plate for a time-of-flight mass spectrometer, comprising: a target plate body 1, a first viscous groove 2 and a second viscous groove 2 and a second viscous groove arranged on the front of the target plate body 1 for fixing a flexible filament A viscous groove 3, the first viscous groove 2 and the second viscous groove 3 are provided with replaceable viscous substances.

[0030] This embodiment and the following embodiments are used for the viscous detection target plate of the matrix-assisted laser desorption ionization time-of-flight mass spectrometer. For the replaceable viscous substance, the double-sided adhesive is used as an example, and for the fixed flexible filament Taking hair 100 as an example, in other equivalent embodiments, it can be applied to other application scenarios where flexible filaments need to be fixed on the detection target...

Embodiment 2

[0032] Please refer to Figure 1 to Figure 6 , the second embodiment of the present invention is:

[0033] A viscosity detection target plate used in a time-of-flight mass spectrometer, on the basis of the first embodiment above, the first viscosity groove 2 and the second viscosity groove 3 form a certain angle. Such as figure 2 As shown, the first viscous groove 2 and the second viscous groove 3 in this embodiment form an angle of 30°. In other equivalent embodiments, it is sufficient that the first adhesive groove 2 and the second adhesive groove 3 are not perpendicular to each other.

[0034] combine figure 1 , figure 2 , Figure 5 and Figure 6 It can be known that the target board body 2 is provided with at least one accommodating groove 11 for the hair 100 to pass between the first viscous groove 2 and the second viscous groove 3 . In this embodiment, a plurality of accommodating grooves 11 are provided on the target plate body 2 and are parallel to each other,...

Embodiment 3

[0035] Please refer to Figure 1 to Figure 6 , Embodiment three of the present invention is:

[0036] A kind of viscous detection target plate for time-of-flight mass spectrometer, on the basis of above-mentioned embodiment three, such as figure 2 As shown in , in this embodiment, two first viscous grooves 2 and one second viscous groove 3 are provided, and the second viscous groove 3 is arranged between the two first viscous grooves 2 . In other equivalent embodiments, at least one first adhesive groove 2 is provided, and at least one second adhesive groove 3 is provided. When there are multiple first viscous grooves 2 and second viscous grooves 3 , the first viscous grooves 2 and the second viscous grooves 3 are arranged at intervals.

[0037] The setting of multiple first adhesive grooves 2 and the second adhesive grooves 3 can more flexibly adapt to detection scenarios of hairs 100 of different lengths.

Abstract

The invention provides a viscosity detection target plate for a time-of-flight mass spectrometer and a using method. The detection target plate comprises a target plate body, a first viscosity grooveand a second viscosity groove, wherein the first viscosity groove and the second viscosity groove are formed in the front face of the target plate body and used for fixing a flexible filament. According to the invention, the flexible filament is adhered to the surface of the target plate through the viscosity grooves to be fixed; meanwhile, an accommodating groove for accommodating the flexible filament is formed in the surface of the target plate body and is used for limiting the swinging of the flexible filament, so that the flexible filament is rapidly and stably fixed on a detection targetplate of a matrix-assisted laser desorption ionization time-of-flight mass spectrometer.

Description

technical field [0001] The invention relates to the field of hair detection for drug abuse, in particular to a sticky detection target plate used for a time-of-flight mass spectrometer and a method for using it. Background technique [0002] At present, flexible filaments refer to flexible and slender objects, such as hair, wool, string and so on. Among them, human body objects such as hair are used as biological samples to detect drugs, stimulants or psychotropic substances. This method can detect whether a person has taken drugs for a long period of time, and can also detect some new drugs. At the same time, the sampling difficulty is low and the detection accuracy is high. [0003] In this method, the hair is usually placed directly on the target plate, so that the hair is easy to move, which is not conducive to detection. That is, the prior art lacks a fast and stable device or method for fixing flexible filaments. Contents of the invention [0004] The purpose of t...
