Examination of Firearms Review: 2007 to 2010 - Interpol

Solution:
High sensitivity analytical techniques (primarily chromatographic) provide
detailed profiles of trace-level impurities, ions, trace metals, and stable isotopes.
Identification of individual impurities enhance origin identification and
comparative analyses and also aid in development of internal standards for
improved accuracy and precision of analysis.
In-depth analysis via improved instrumental methodologies help identify
discriminatory components in impurity profiles. Computer databases, sorting
programs, and pattern recognition/neural networks provide enhanced data
handling and analysis, enabling and improving comparative analyses.
Case reports are generated for the forensic and enforcement communities.
