Problems solved by technology

Furthermore, it has been shown that S produced by the method of GB1804040.2 2 N 2 Very good at recovering different types of imprints from a variety of materials and objects, especially those that have been tampered with or subjected to a force or treatment that may make the imprint more difficult to utilize other visualization techniques restore or manifest
However, using S 2 N 2 The problem with vapor is that it tends to leave a staining residue on the surface of the device from which the vapor was generated, which leaves the device in an undesirable state and makes it difficult to make objects visible in the device to assess any progress regarding the development of the imprint

Embodiment Construction

[0080] Such as figure 1 and figure 2 As shown, the device 1 comprises: a circular base 2, made of stainless steel and providing a surface 2a and surrounded by a circular perimeter 3; and a transparent circular housing 4, the transparent circular housing 4 Made of glass and defines housing edge 4a. The housing 4 measures approximately 201 mm in diameter and 200 mm in height and is shown placed over the peripheral portion 3 to form a sealed chamber 5 with a volume of 6.5 liters. The peripheral portion 3 is made of rubber to help form an airtight seal between the peripheral portion 3 and the housing edge 4a. An object (not shown) comprising an imprint may be arranged on or near the base 2 (for example, on an object holder (not shown)) such that when the movable housing 4 is arranged on the surface 2a, the Subject is enclosed in a sealed chamber. A vacuum port 6 is provided on the base 2 for applying vacuum to or releasing vacuum from the sealed chamber 5 . In the center of ...

Abstract

The invention relates to an apparatus for the visualisation of a print on an object, the apparatus comprising: a base comprising a heating element in thermal communication with a receptacle for storing an agent, a housing to provide a sealed chamber; and a port for applying a vacuum to, or releasing a vacuum from, the sealed chamber. The invention is particularly for the visualisation of a fingerprint such as a latent fingerprint. The invention also relates to a system incorporating the apparatus with a cartridge and agent, and associated methods and uses for visualising a print on an object.

Description

technical field [0001] The present invention relates to a device for visualizing a print on an object, in particular a fingerprint such as a latent fingerprint. The present invention also relates to systems and associated methods and uses, particularly for the extraction of sulfur tetranitride (S 4 N 4 ) metal halide adducts to generate disulfide dinitride (S 2 N 2 ) to make the imprint on the object appear. Background technique [0002] The use of imprints in solving crimes is still very important. Since the late 19th century, police agencies around the world have used fingerprinting methods to identify suspected criminals. The basis of conventional fingerprint technology is based on the observation that the skin on the surface of the palms and soles develops lines that are unique to each individual and do not change over time (so-called papillary lines). [0003] There are three different types of fingerprints: visible, indentation, and latent. Visible imprints are ...
