The car was then lifted successfully by the crane without the bond breaking. Using the same type of CA, the same brand and type of foil boat, the same heat, the same humidity and, with the noted exceptions, the same time exposures will enhance productivity in case work and lessen dependence on guesswork. The reaction also stabilizes the ridge detail to better preserve for possible future enhancement (through use of fingerprint powder . Then check on the development of the fingerprints.

Relying on gravity or an insufficiently powered fan to distribute the CA vapor uniformly throughout the chamber will give uneven and erratic results. However, it is important for defense attorneys to know, and to inform the jury, that the techniques used to locate and identify fingerprints are far from a perfect science. An appropriately sized container will help the prints develop faster and more clearly. Heat is probably the most misunderstood, and widely varied, of the variables under discussion. D.

The ACE-V process requires an independent examination by a second examiner. If the CA vapor is not distributed evenly within the chamber, it is possible to get both under-developed prints and over-developed prints in the same processing cycle, even on the same piece of evidence. About: My name is Jason Poel Smith. The process of fingerprint fuming is relatively easy. These are meant to remove vapors only as they are drawn over the filter media, typically charcoal and other solvent/acid/amine specific media. a. There are serious risks with using Superglue if you do not use the materials in an appropriate fashion. The water vapor method is extremly simple in theory and in practice.
