Development and Evaluation of a Targeted Gas Chromatography Mass Spectrometry (GC-MS) Method for Analysis of Synthetic Cathinones

October 8, 2021

Author(s)

Edward Sisco, Amber Burns, Arun Moorthy

With the increased prevalence of novel psychoactive substances (NPSs), seized drug analysis has become more complex and challenging due, in part, to changing chemical structures and isomeric species. To assist in addressing these challenges a series of

Investigating the Transfer of Drug Particulate onto Evidence Packaging During Routine Case Analysis

October 8, 2021

Author(s)

Edward Sisco, Liz Robinson, Rebecca Mead, Charles R Miller

The presence of drug residue and drug background in a forensic context continues to be of interest for a variety of reasons ranging from its potential use as a means for presumptive identification to ensuring the safety and well-being of drug chemists

NIST/NIJ DART-MS Data Interpretation Tool User Manual

Author(s)

Edward Sisco, Arun Moorthy, Stephen Tennyson, Ruthmara Corzo

Screening and Confirmation of Seized Drugs Utilizing Portable Raman Spectroscopy (TacticID) and Direct Analysis in Real Time-Mass Spectrometry (DART-MS)

October 8, 2021

Author(s)

Travon Cooman, Colby E. Ott, Kourtney A. Dalzell, Amber Burns, Edward Sisco, Luis E. Arroyo

The continuous change of the drug landscape in the United States demands adaptation and incorporation of emerging analytical methods that preferably allow onsite screening but are also capable of supporting the analysis of seized drugs received at forensic

The min-max test: an objective method for discriminating mass spectra

October 8, 2021

Author(s)

Arun Moorthy, Edward Sisco

Development and Evaluation of a Synthetic Opioid Targeted Gas Chromatography Mass Spectrometry (GC-MS) Method

August 30, 2021

Author(s)

Edward Sisco, Amber Burns, Arun Moorthy

A method for the targeted confirmation of synthetic opioids and related compounds was developed and evaluated. Using an 11-component test solution a method was developed that focused on maximizing chromatographic separation and understanding the influence

Cannabis Quality Assurance Program: Exercise 1 Final Report

July 27, 2021

Author(s)

MARYAM ABDUL-RAHMAN, Melissa M. Phillips, Walter Brent Wilson

NIST launched a CannaQAP in 2020 to improve the comparability of the analytical measurements in forensic and Cannabis (hemp and marijuana) testing laboratories. CannaQAP is an interlaboratory study mechanism that is similar to a proficiency testing scheme

Open port sampling interface mass spectrometry of wipe-based explosives, oxidizers, and narcotics for trace contraband detection

July 19, 2021

Author(s)

Thomas P. Forbes, Jeffrey Lawrence, Changtong Hao, J Greg Gillen

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

Confined DART-MS for rapid chemical analysis of electronic cigarette aerosols and spiked drugs

June 29, 2021

Author(s)

Thomas P. Forbes, Shannon Krauss

A confined direct analysis in a real time mass spectrometry (DART-MS) system and method were developed for coupling directly with commercial electronic cigarettes for rapid analysis without sample preparation. The system consisted of a confining heated

Analysis of Benzodiazepines by Thermal Desorption Direct Analysis in Real Time Mass Spectrometry (TD-DART-MS)

June 17, 2021

Author(s)

Edward Sisco, Sydney Jones, Ioan Marginean

Novel psychoactive substances (NPS) present a prominent and increasing concern for forensic laboratories across the country. Benzodiazepines, which are one class of NPS, have experienced a growing presence in the United States due, in part, to the

Creation and Release of an Updated NIST DART-MS Forensics Database

June 17, 2021

Author(s)

Edward Sisco, Arun Moorthy, Laura M. Watt

Facing increasing caseloads and an everchanging drug landscape, forensic laboratories have been implementing new analytical tools. Direct analysis in real time mass spectrometry (DART-MS) is often one of these tools because it provides a wealth of

Detection of Trace Drugs of Abuse in Baby Formula using Solid Phase Extraction Direct Analysis in Real Time Mass Spectrometry (SPE-DART-MS)

June 17, 2021

Author(s)

Laura M. Watt, Edward Sisco

The intentional or unintentional adulteration of baby formula with drugs of abuse is one of the many increasingly complex samples forensic chemists may have to analyze. This sample type presents a challenge because of a complex matrix that can mask the

Forensic Applications of DART-MS: A Review of Recent Literature

June 17, 2021

Author(s)

Edward Sisco, Thomas Forbes

The need for rapid chemical analyses and new analytical tools in forensic laboratories continues to grow due to case backlogs, difficult to analyze cases, and identification of previously unseen materials such as new psychoactive substances. To adapt to
