Description
Technical field
The invention belongs to the technical field of trace organic substance qualitative detection, relate generally to a kind of fingerprint manifestation spray iodine preparation, more particularly, the present invention relates to a kind of fingerprint manifestation spray iodine preparation of extracting for fingerprint, impression of the hand.
Background technology
It is variant that fingerprint has people, throughout one's life the feature of constant and tactile thing trace.Science correctly find, extract, manifest identify fingerprint for carrying out investigation, punishing crime has important practice effect; Fingerprint identification is one of the most reliable method of carrying out individual identification, in forensic science, be used for verification, disclose and confirm crime; In the investigation of accident and processing, the victim of some accidents or natural disaster or died, while being with the naked eye beyond recognition, extract their fingerprint because of the condition of the injury or other reasons, and definite identification often can be provided; Same application also can be in security protection, safety check and commercial affairs as aspects such as the unlatching of automatic door lock, access management and controls of stamping; Along with the application of the universal and automatic system of fingerprint recognition of computer technology, fingerprint technique and be about to obtain applying more and more widely in people's life.
1876, Charles Robert Richet Aubert invented the technology that manifests fingerprint with iodine, became and founded the first of fingerprint manifestation method.Find that from Aubert iodine manifests the technology of fingerprint, fingerprint manifestation, from initial single and simple method, develops into the professional technique that has become the subject knowledges such as an integrated use physics, chemistry, biology and technology now.Manifest fingerprint with iodine and can apply on most of non-metal kind objects, be suitable for the fresh or more outmoded perspiration oils and fats impression of the hand on the sample surface that manifests the great majority infiltrations such as smooth paper, paraffin paper, carbon paper, articles made of bamboo, true qualities wood, wall, plastics, spun yarn textile, glass and non-infiltration.Iodine is smoked all effective to fresh or more outmoded impression of the hand, and is not holding trace on trace body, does not also destroy former vestige, unlikely damage fingerprint and object; Can repeated multiple timesly exert a gradual, corrupting influence on and manifest; Also can after iodine disappears, use additive method instead and manifest, not impact effect.But have some limitations with the fingerprint that iodine fumigation manifests on scene, as manifest the impression of the hand on some special objects such as picture wall, wallpaper, directly come smoke to show with iodine and just seem and be not special convenience.Nineteen eighty-three JIUYUE, German Bi Jieer and Ci Aowen put forward to have invented liquid spray iodine preparation, have overcome iodine fumigation and have not been suitable for the defect that manifests the lip-deep colourless impression of the hand of impermeability object.1987, there is iodo-benzoflavone spray, it can overcome often can separate out the shortcoming of iodine crystal when former method is used in scene of a crime.
The Guo Wei of China Peoples Public Security University and Chen Ruili etc. have invented a kind of novel fingerprint displaying spray iodine preparation, and be published on China Peoples Public Security University's journal (natural science edition) 17-19 page of the 4th phase publication in 2007, this novel fingerprint displaying spray iodine preparation comprises normal hexane 300ml, dichloromethane 500ml, ether 200ml, iodine 40-50g, dibromo phenyl fluorone 0.6-1.0g; Novel spraying iodine preparation is for the impression of the hand on the special objects such as ceramic tile, coating wall, wallpaper, and even to all being had and manifest preferably effect by the impression of the hand of leaving on the ceramic tile of washing, but the stability of described fingerprint displaying spray iodine preparation etc. need further to be improved.
Summary of the invention
In order to solve the above-mentioned technical problem existing in prior art, the object of the present invention is to provide a kind of fingerprint manifestation spray iodine preparation.Described fingerprint manifestation spray stability of iodine dose is good, and the fingerprint on more outmoded fingerprint and ceramic tile, coating wall is all had to the good effect that manifests.Fingerprint manifestation of the present invention spray iodine preparation can be applied to manifesting of fingerprint in scene of a crime and the scene of the accident.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of fingerprint manifestation spray iodine preparation, is characterized in that comprising following component: normal hexane 600-750mL, ethyl acetate: 300-450mL, iodine: 25-60g, phenylfluorone: 0.5-1.2g.
As preferably, described fingerprint manifestation spray iodine preparation is composed of the following components: normal hexane 600-750mL, ethyl acetate: 300-450mL, iodine: 25-60g, phenylfluorone: 0.5-1.2g.
As preferably, described fingerprint manifestation spray iodine preparation is composed of the following components: normal hexane 600-700mL, ethyl acetate: 350-450mL, iodine: 35-50g, phenylfluorone: 0.5-1.0g.
As preferably, the volume ratio of described ethyl acetate and normal hexane is 1: 1.6-1.8.
As preferably, the volume ratio of described ethyl acetate and normal hexane: 1: 1.72.
As preferably, described fingerprint manifestation spray iodine preparation is composed of the following components: normal hexane 632mL, ethyl acetate: 368mL, iodine: 42g, phenylfluorone: 0.8g.
As preferably, described phenylfluorone is selected from 2,3,7-trihydroxy-4, the bromo-9-phenyl of 5-bis-6-fluorone, 2,3, one or more in 7-trihydroxy-9-(4 '-nitro) phenylfluorone or o-chloro phenenyl fluorescent ketone.
As preferably, described phenylfluorone is 2,3,7-trihydroxy-4, the bromo-9-phenyl of 5-bis-6-fluorone.
On the other hand, the invention still further relates to a kind of purposes of fingerprint manifestation spray iodine preparation, it manifests for fingerprint.
On the other hand, the invention still further relates to a kind of using method of fingerprint manifestation spray iodine preparation, described fingerprint manifestation spray iodine preparation is contained in automiser spray, sprayed in the region that scene is suspicious.
In the fingerprint of human body or impression of the hand, remain the oozy EM of skin, in these materials, contain a large amount of protein being formed by several amino acids.And amino-compound issues biochemical reaction in the existence of some particular matter, join oxygen coupling compound as some, will produce change color.In addition, iodine also can be produced change color by the absorption of amino-compound, but with the rapid distillation of iodine, its color just disappears very soon, therefore the effect of fingerprint manifestation spray iodine preparation of the present invention and fingerprint or impression of the hand should be thought the embodiment of the comprehensive function of two kinds of mechanism of physics and chemistry.When fingerprint manifestation of the present invention spray iodine preparation can be sprayed on the material surface such as white wall, glass and white ceramic tiles with residual impression of the hand with Sprayable, just the protein transduction that leaves impression of the hand is changed into colour substance and promptly display, thereby reach the object of sampling; In addition, fingerprint manifestation spray iodine preparation of the present invention stable performance, can place and keep effect stability to the several months in several 10 days; And comparatively outmoded fingerprint is also had to the excellent effect that manifests; Not only can be applicable to manifesting of fingerprint on the sample surface of the infiltration of the great majority such as paper, paraffin paper, carbon paper, articles made of bamboo, true qualities wood, wall, plastics, spun yarn textile, glass and non-infiltration or impression of the hand, but also can manifest fingerprint or impression of the hand on the special objects such as ceramic tile, coating wall.
The specific embodiment
