This will help forensic labs correctly determine whether a seized material is hemp, which is legal in all 50 states, or marijuana, which is a controlled
When it comes to crime scene investigation, a lot needs to happen behind the scenes so that judges and juries can trust the validity of evidence presented at
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose
Fire Debris Fire debris analysis involves the collection, analysis, and interpretation of data of debris collected from fire scenes. Samples are typically analyzed by gas chromatography mass spectrometry which results in a complicated chromatogram that must be interpreted. Projects in this area are
Development of Low-Volume Drop Blood Drug Screening Tools This project aims to leverage recent NIST advances in ambient ionization mass spectrometry to develop platforms for low-volume blood drug screening. Direct Analysis in Real Time Mass Spectrometry (DART-MS) and Paper Spray Ionization Mass
Rapid screening for chemical traces of explosives and narcotics is widely used to support homeland security and law enforcement. These target compounds span a range of physicochemical properties from organic to inorganic, with preferential ionization pathways in both negative and positive mode
This report is a summary of a workshop convened to capture the analytical and data challenges inherent to the detection, identification, and monitoring of
Reductions in instrument size, weight, and power continue to facilitate the development and application of field-deployable devices for investigative purposes

Ultra-high molar mass polyethylene (UHMMPE) is commonly used for ballistic-resistant body armor applications due to the superior strength of the fibers
The Large Aperture Scanner (LAS) scans a radar transceiver over a 5 meter by 20 meter aperture. Image reconstruction techniques enable a three-dimensional
The Smiths Detection 6046si cabinet x-ray system was designed for security screening of bags, parcels and other objects of similar size. The system runs at 160
X-ray backscatter systems are used for the screening of personnel for hidden weapons and other contraband. Unlike conventional radiographic x-ray systems
The NIST-developed reference ballistic chronograph (RBC) provides repeatable measurements of the speed of a bullet that will impact a test article, such as
