Phone Two formulations for luminol testing have been used extensively, Luminol I de-scribed by Grodsky (11) and Luminol II described by Weber (12). If blood is visible at the scene, it should be preserved, appropriately packaged, and sent to a forensic laboratory for analysis without luminol testing. If the plant species in question is found only in limited areas, its presence at the crime scene may indicate where suspects have been or where they live. Blood; Chemiluminescence; Hidden bloodstains; Luminol photography; Paint; Time since concealment. On February 7, 2004, a diver was doing a damage work to a pier in Neskaupstaur. Simulated signatures based upon recollection contain a combination of the forgers own writing habits and his recollection of the victims habits. These findings highlight the fact that bloodstains concealed by paint could be effectively detected by luminol reagent, despite the nature and ageing of concealment and thereby provide a lead to the investigation. The highest intensity of chemiluminescence was shown by concealed bloodstains on dry wall and metal surfaces, despite the number of layers of concealment. Luminol was first used to detect latent bloodstains in 1937 (1). A study undertaken by scientists from the UV and published this month in the journal entitled Naturwissenschaften, has shown that if materials stained with blood are washed with products containing active oxygen, the luminol, phenophthalene and human haemoglobin tests give a negative result. To exhibit its luminescence, the luminol must first be activated. In addition to using luminol to locate traces of blood, it can be used to find bloodstained areas which may have been washed, and to ex- Plataforma SINC.

His research showed that the older the stain, the longer and more pronounced However, each method has limitations. Before the Luminol test, there had been no visible sign of the struggle. In the reaction, luminol is oxidized and its electrons elevated to an excited state. Police retrieved and analyzed the footprints and cloth impressions that he left on the damp soil of the crime scene. Luminol is an organic compound which, when oxidized, emits light a phenomenon known as chemiluminescence. It is well known to experienced forensic scientists who use luminol that long lasting glow is indicative of blood. Usually the activator is a solution of hydrogen peroxide (H2O2) and sodium hydroxide (NaOH) in water. One problem with luminol is that the chemical reaction can destroy other evidence in the crime scene. Police technicians use luminol and . A forged signature presents other problems. This later went on to give significant leads during criminal investigations from the examination of blood. Hairs possess class characteristics (patterns that naturally occur in specific percentages of the population) that indicate some general features of the individual from whom they are obtained, such as what diseases he may have and sometimes what race he belongs to.
