Better results. Faster. As soon as your sample comes through the door, we spring into action to properly log it, store it, and notify the individual scientists that will be diligently working on your project. Then it's off to specialized sample preparation and analytical probing by our fleet of cutting edge instruments. You'll have data, interpretation, and solutions in no time.
Biochemists. Materials scientists. Forensic experts. We turn complexity into a competitive advantage.
Gateway Analytical has carefully assembled a diverse team of curious experts. When the other guys run away from difficult problems or second guess their approach, our scientists move in to take a closer look with a forensic-based framework. Our process is focused on outcomes and driven by experts that have seen it all. You bring challenges. We deliver creative solutions.
You're looking for quality. We collect lab certifications. It's a perfect match.
We're not just another analytical lab. Why not? We spent years building a leading position in the highly-regulated pharmaceutical industry. That means our facilities are FDA-inspected, cGMP certified, and maintain ISO 9001 (quality management) and ISO 17025 (testing and calibration) standards. Simply put, there's a high bar for quality in all our work that others just can't match.
We've ditched one-size-fits-all customer service for a more personal, collaborative approach.
When you need us, call us. We're always here to answer your questions. As our growing list of returning customers has learned, you'll get to know the individual scientists working with your team to deliver results. They're real people. Our innovative real-time collaboration technology even allows us to demonstrate results and provide updates -- live from the lab.
Gunshot residue analysis is a common request in forensic laboratories with cases that question whether or not an
individual fired a firearm. When a firearm is fired, several types of residues are expelled from the openings on the firearm. Primer residues, specifically, are detected in GSR analysis. Primer residues are made of particles which contain elements found in the primer of the ammunition used in the firearm. The common Sinoxid-type primers can yield what have been characterized as ‘particles characteristic of gunshot residue particles.’ Like any combustion reaction, the chemical reaction responsible for firing a gun requires an initiator, fuel for the reaction, and an oxidizer. Sinoxid primers employ lead styphnate as the initiator, or primary explosive, barium nitrate as the oxidizer, and antimony sulfide as the fuel. When a gun is fired, the primer components vaporize due to the extremely high temperatures produced by the combustion reaction and are pushed out of the openings in the gun, due to the force of the reaction. Upon being released into the environment, the vaporized particles combine and resolidify into single particles, some of them containing a mixture of elemental lead, barium, and antimony. Along with the metals from the primer, gunshot residue particles may also contain reminiscent elements from the propellant mixture, metallic residues from the firearm itself, and residual elements from previous firings of the gun. Particles that are molten in appearance, due to formation in high temperatures, which contain lead, barium, and antimony, have been termed particles characteristic of gunshot residue, or ‘characteristics particles’.
