⩥ Ruhemann's Purple. Answer: The final purple coloured compound
usually produced with the treatment of Ninhydrin
⩥ Small Particle Reagant. Answer: What latent print development
technique is used to process nonporous material that are wet?
⩥ Amino Black. Answer: A dye which stains protein present in blood to
give a blue-black product
⩥ Natural latent fingerprints and fingerprints contaminated from the
environment. Answer: The following types of fingerprints will fluoresce
under appropriate illumination
⩥ Fluorescence Examination. Answer: One of the first processes used in
a sequence of a fingerprint examination
⩥ Adhesive surface of adhesive tapes. Answer: Gentian Violet is a dye
which stains fatty constituents of sebaceous sweat producing an intense
purple image. It is effective for the development of what kind of prints?
,⩥ Naphthalene Black. Answer: Alternative process name for Amido
Black
⩥ Brown. Answer: Iodine vapour is physically absorbed by latent
fingerprint deposits and often fades unless fixed. What color image is
formed using iodine vapour?
⩥ Gentian Violet. Answer: What can interfere with the forensic
examination for handwriting, body fluids, and ink?
⩥ Amino acids. Answer: Ninhydrin is a general purpose fingerprint
reagent for paper and some other porous surfaces. What component of a
fingerprint deposit does it react with?
⩥ Several weeks. Answer: How long does it generally take for
Ninhydrin treated prints to fully develop naturally?
⩥ Heating and humidification. Answer: The development of Ninhydrin
treated prints may be accelerated with the use of:
⩥ Ink running. Answer: Ninhydrin which uses a Freon solvent virtually
eliminates the following problem when processing porous materials for
latent prints
,⩥ Ninhydrin. Answer: What is applied using the method of dipping,
brushing, swabbing or spraying?
⩥ silver-based. Answer: Physical developer (PD) is what kind of
aqueous reagent?
⩥ Grey-silver. Answer: Physical developer reacts with components of
sebaceous sweat to form what colored deposit?
⩥ Wetted. Answer: Physical developer is a very effective reagent for
developing latent fingerprints on paper which has been?
⩥ Aluminum. Answer: These flake powders have been shown to be
more sensitive than most types of powders
⩥ Silver Nitrate. Answer: Which latent print development technique was
replaced by the Ninhydrin/Physical Developer combination for treating
porous materials
⩥ Chlorides. Answer: Silver Nitrate reacts with what component present
in fingerprint deposits
⩥ wet. Answer: Small particle reagent (SPR) is a latent print
development technique that may be used on all non-porous surfaces
including those which are
, ⩥ Fats. Answer: What does Small Particle Reagent adhere to in the
fingerprint deposit?
⩥ Molybdenum Disulphide. Answer: Small Particle Reagent is
comprised of what fine particles?
⩥ Grey. Answer: Small Particle Reagent forms what color deposit?
⩥ Sudan Black. Answer: The best latent print development technique for
use on non-porous surfaces which are contaminated with grease,
foodstuffs, or dried deposits of soft drinks
⩥ Cyanoacrylate. Answer: An alternative process name for superglue is
⩥ White. Answer: Superglue polymerizes on some latent fingerprints to
produce what colored deposit
⩥ water. Answer: Superglue is thought to react primarily with what
component in that latent print deposit
⩥ non-porous. Answer: Superglue is most suitable for what kinds of
surfaces?
