| Two Complete Gunshot Residue (GSR) Tests in One! The new design incorporates standard 'sticky-tab' carbon tape particle collection devices, which meet the requirements of most State Crime Labs that conduct SEM (Scanning electron microscope) testing for GSR. The investigator first sticky-tab swabs the suspect according to approved techniques, places sticky tabs into an evidence envelope and seals envelope with evidence tape (all included) for delivery to evidence technician or forensic lab. The investigator then dry-swabs the suspect with proprietary L.E.T. swab and supplies a chemical reagent. A blue reaction on the swab at the 5-minute interval indicates a presence of nitrocellulose. When that blue reaction appears in the form of small ""spots"" or ""specks"", it is considered highly probable that this suspect recently fired a weapon and warrants further investigation. ISID-2 is a ""binary"" test kit: It contains everything needed to collect GSR evidence from your suspect both for the investigation (instant field results) and separately for the crime lab submission (evidentiary). Don't allow your shooter to simply walk away! This Gunshot Residue (GSR) field test is Accurate! Over 90% accuracy rate through extensive field testing. Helps Law Enforcement to quickly determine who has fired a weapon while in the fieldó yields results in five minutes! Effective! Results obtained in field yield investigative data. When desired, positive test results can be preserved and delivered to Crime Lab for SEM testing, which can provide evidentiary data. Easy! Minimal training required. Simply sticky-tab swab the suspect, place tabs into an evidence envelope, seal with evidence tape and send to the forensic lab. Kit weighs less than 5 ounces Long shelf-life, can be stored in squad car trunk. Affordable! Cost is a fraction of most tests. Now GSR testing can be performed on a range of suspects, or to analyze a crime scene. Sandia National Laboratories saysì...statistics show that the first 72 hours are the most critical time for investigation of a crime scene. (This) field-portable test kit will provide the law enforcement community with immediate confirmation of recent gun use and assist in rapidly focusing on key suspects.î ì...this test has been shown to detect as little as 700 nanogramsof nitrocellulose.î |
