Embodiment 1

[0027] The analysis card is made of a cover film 1 and a polydimethylsiloxane color developing substrate 2. The cover film 1 is composed of a non-woven fabric 3 with adhesive backing and an isolation film 4, wherein the material of the isolation film 4 is a poly pair ethylene phthalate; the polydimethylsiloxane color developing substrate 2 is provided with an array of 9 concave cuboid 5 structures, and a reagent module 6 is placed in the cuboid 5, and the reagent module 6 and the instruction manual 8 The discoloration information of the explosive detection reagents is in one-to-one correspondence, and the specific operation is carried out according to the following steps:

[0028] To prepare the polydimethylsiloxane chromogenic substrate:

[0029] a. Place polydimethylsiloxane and peroxide vulcanizing agent in a beaker at a volume ratio of 10:1 and stir until they dissolve evenly to obtain a polydimethylsiloxane solution. After standing for 30 minutes, take 5 ml of polydimethy...

Embodiment 2

[0040] The analysis card is based on Embodiment 1, and the specific operation is carried out according to the following steps:

[0041] To prepare the polydimethylsiloxane chromogenic substrate:

[0042] a. Place polydimethylsiloxane and peroxide vulcanizing agent in a beaker at a volume ratio of 10:1 and stir until they dissolve evenly to obtain a polydimethylsiloxane solution. After standing for 30 minutes, take 5 ml of polydimethylsiloxane. The methylsiloxane solution was slowly poured into the resin-made cuboid template. After standing for 10 minutes, the printed instruction manual 8 was slowly placed on the surface of the polydimethylsiloxane solution, placed for 10 minutes, and then 5ml of polydimethylsiloxane was taken. The base siloxane solution was poured into the cuboid template, placed on the anti-template, and pressed out 9 concave cuboid 5 structures to form an array; then the cuboid template and the anti-template were put into an oven together at a temperature of...

Embodiment 3

[0053] The analysis card is based on Embodiment 1, and the specific operation is carried out according to the following steps:

[0054] To prepare the polydimethylsiloxane chromogenic substrate:

[0055] a. Place polydimethylsiloxane and peroxide vulcanizing agent in a beaker at a volume ratio of 10:1 and stir until they dissolve evenly to obtain a polydimethylsiloxane solution. After standing for 30 minutes, take 5 ml of polydimethylsiloxane. The methylsiloxane solution was slowly poured into the resin-made cuboid template. After standing for 10 minutes, the printed instruction manual 8 was slowly placed on the surface of the polydimethylsiloxane solution, placed for 10 minutes, and then 5ml of polydimethylsiloxane was taken. The base siloxane solution was poured into the cuboid template, put on the anti-template, and pressed out 9 concave cuboid 5 structures to form an array; then put the cuboid template and the anti-template together into an oven, the temperature was 70 °C,...

Abstract

The invention provides a preparation method and application of an array type chemical colorimetric instant analysis card. The analysis card is made of a film and a polydimethylsiloxane (PDMS) color developing substrate. When in use, open the aluminum Take out the analysis card from the plastic bag, tear off the coating layer, wipe a small amount of the test object with the analysis card loaded with the detection reagent, and ensure that the test object is evenly distributed in the 9 areas of the reagent module of the analysis card. Wait for the test object and the reagent module After sufficient exposure for 10 s, check and compare with the color information on the manual to clarify the type and specific name of the object to be tested. It truly realizes the functions of sampling, simultaneous contact with all detection reagents, color development, identification, and operation instructions, which greatly reduces the sampling operation steps and difficulty, and improves the efficiency of detection and analysis and the accuracy of test results. It overcomes the shortcomings of dropping reagents in sequence or needing to mix detection reagents, performing sequence analysis, and poor detection timeliness.

Description

technical field [0001] The invention belongs to the field of detection and analysis of explosive residues, and in particular relates to a preparation method and application of an array type chemical colorimetric instant analysis card. Background technique [0002] At present, the products for rapid detection and analysis of explosives are becoming more and more mature. Based on the technology of chemical colorimetric qualitative analysis, the main products used in the international community include rapid detection kits, drop bottles, spray bottles, detection pens, test kits and the introduction of machine vision. Explosive detectors, etc., these products can already realize the detection and analysis of explosive residues. [0003] However, in practical applications, there are many inconvenient situations, such as the inconvenience of carrying due to the volume, the need to use sampling paper for advance sampling, or the sampling vessel material is too hard to complete samp...
