The invention relates to the production of washing powders of stabilized or enhanced appearance which contain a fluorescent whitening agent of the formula ##STR1## wherein X 1 is hydrogen, chlorine, bromine, alkyl or alkoxy, X 2 is hydrogen or alkyl and M is hydrogen, an alkali metal or ammonium ion. The stabilizing or enhancement of the appearance is effected by first dissolving or dispersing ...
Sep 03, 2019·The efficacy of three fluorescent variant of the SNP powders and commercial fluorescent powder (CFP) was determined by developing latent fingerprints on different multicoloured substrates namely two multicoloured metal cans, glossy wallpaper, borosilicate measuring cylinder, plastic multicoloured bottle, patterned porcelain mug, multicoloured ...
A very sensitive, contrasting fluorescing latent fingerprint powder for use against extremely dark or transparent backgrounds. Available in 2 oz and 16 oz sizes. Yellow X Fluorescent Latent Print Powder
The effectiveness of three fluorescent variant of the SNP powders and commercial fluorescent powder (CFP) was investigated by developing latent fingerprints deposited on different multicoloured ...
There are 2 primary ways of making fingerprints fluoresce through the use or treatment with; Fluorescent Powders or Fluorescent Liquid Dyes. Fluorescent Powders are used widely as the primary method of fingerprint treatment at crime scenes when using a Forensic or Alternate Light Source. They are available in various colors.
Apr 01, 2015·An IR fluorescent fingerprint powder has the capacity to eliminate the need for careful powder selection either at the scene or laboratory, as background interference can essentially be negated. Herein, we report the development of a novel, naturally occurring, non-toxic IR fluorescent fingerprint powder that has been shown to be suitable for ...
It's the best of both worlds. When exposed to a black light, latent fingerprints dusted with Fluorescent Magnetic Fingerprint Powder glow with unbelievable intensity and contrast. And there's no risk of damaging or scratching latent prints because only the powder touches the print!
Sep 10, 2005·Fluorescent powder was applied by means of a magnetic brush onto the latent fingerprint samples. Generally, these types of powders are most effective to develop the prints on non-porous surfaces. Care was taken to apply the powder almost uniformly onto fingerprint samples.
Fingerprint powder and method for developing latent fingerprints therewith, such powder comprised of a powder carrier, especially a mixture of silica and talc, containing a coloring agent, preferably a fluorescent dye. The fingerprint powder can be applied by blowing the powder over a surface containing latent fingerprints, or by brushing or pouring the powder on such surface, or by immersion ...
A demonstration of when to use fluorescent fingerprint powders. Mike will show you how traditional powders may not show you the latent prints you develop.

Fluorescent variant of silica nanoparticle powder synthesised from rice husk for latent fingerprint development Revathi Rajan1,2, Yusmazura Zakaria3, Shaharum Shamsuddin3 and Nik Fakhuruddin Nik Hassan2* Abstract Background: Fingerprint, though still remains one of the best possible means of individual identification, is often
Aug 01, 2017·One powder that has not been studied thus far, given its infancy, is the infrared (IR) fluorescent fingerprint powder recently reported by King et al. .This material comprises finely milled Spirulina platensis, a naturally occurring and non-toxic algae which contains components capable of near-infrared (NIR) fluorescence within its matrix.This IR fluorescent powder is suitable for use on both ...
wavelengths as common fluorescent fingerprint treatments, can prevent the successful imaging of fingerprints. However, when dusted with . fp. N. ATURAL ® IR fluorescent powders, interference can be removed to reveal high contrast prints. Visualising Fingermarks on Polymer Banknotes. Traditional methods of examining paper banknotes,
Dec 01, 2011·The number of loci obtained from DNA profiles were compared by the type of surfaces (Fig. 1A) and color of fluorescent fingerprint powder used for dusting (Fig. 1B).Considering the same type of surface, the number of loci, which alleles were present, was comparable to those obtained from the undusted fingerprint samples.
Fluorescent brightener for laundry liquid is specially used in laundry liquid, detergent powder and other washing products, and all the indicators meet international requirements before using. Whitening of fluorescent whitening agents is a physical phenomenon, not a chemical reaction.
