Magnetic Developer for papillary and podorales Latent fingerprints, palmprints

摘要

Magnetic Powders are variants of developers with the colors Black, Dark Brown, Light Red, dark red, red, Light Blue, Light Green, White, and Yellow for the development and Rise of Latent papilar fingerprints from a base of a mineral, which contains in its compo As the mineral Magnetite and Hematite as a key component, in addition,Other metal Elements, which after undergoing a process of Sieving using sieves with diameters between 50 and 100 microns, drying at a temperature range between 80 to 90 C was Mixed separately with several pigments in powder of inorganic and inorganic in nature and the Some cases with a Mineral from the family of Aluminum silicates in different Ranges.That is what gives it special characteristics and novel, not reported up to now in the literature consulted. The developer is applied with a Brush On the surface of the Magnetic Medium containing the footprint. The General and specific characteristics of the Fingerprint are Sharp, to be set up and then photographically.For the identification and characterisation of all the components used in the production of Revealing Latent Magnetic Powders using analytical techniques like Scanning Electron Microscopy coupled with x-ray Analyzer, Fluorescence, x-ray, difra Choice of x-ray and infrared spectroscopy.
