Linde Canada will display its revolutionary latent fingerprint development system in booth #629 during the 97th International Association for Identification (IAI) Education Conference from July 22nd – 28th at the Convention Center in Phoenix, Arizona.

The IAI is the world’s oldest and largest forensic science/identification association. The conference gathers world-renowned professionals who present the most current scientific methodologies and technical products and advances in the identification field.

Fingerprint identification, arguably the most common forensic evidence used worldwide, has taken a huge leap forward with the introduction of the Linde ADROITTM FC 300 latent fingerprint development system, developed by Linde Canada, an affiliate of The Linde Group, which is a world-leading gases and engineering company.

The dry, non-contact technology uses a gaseous application process for developing latent fingerprints, eliminating hazardous carrier solvents used in traditional processing methods and the physical application of these materials by dipping, spraying, brushing and drying.
A prototype of the Linde system has undergone extensive evaluation by a research team at a major US Forensic Crime Laboratory who will present results of their evaluation at the IAI on Wednesday July 25th at 8am.

“The new Linde technology is a flexible tool designed with both the forensic investigator and research scientist in mind.  It’s a dry process, capable of developing latent prints on a wide range of porous and non-porous materials including thermal papers.”

said Calvin Knaggs, Specialty Markets Equipment-Canada.

“The programmed recipe control lends itself to standardized practices, ensuring precision while eliminating the complexities and potential inaccuracies associated with mixing and applying solvent carriers.  This is truly a step change in fingerprint development technology, eliminating many of the storage, safety and environmental problems associated with the current art,” added Calvin Knaggs.

The Linde technology applies detection chemicals by sublimation and dilution in a proprietary carrier gas injected into a low pressure environment. The gas mixture expands, uniformly coating all exposed surfaces (the evidence), thus depositing a thin film which adheres to, or chemically reacts with, the print residue making it visible to the unaided eye or under alternate light source (ALS) or laser excitation.
“The ADROIT TM FC 300’s programmable logic controller (PLC) enables remote monitoring from a central command center via a network, allowing agencies with satellite systems to control the processing regimens and update new process recipes anytime, anywhere in the world,” Knaggs said.
