Forensic and Analytical Toxicology

We are a multidisciplinary laboratory supporting research, service, and teaching and training activities. We conduct research and method development for the chemical analysis of drugs, environmental pollutants, natural products and other toxicants of interest in biological specimens and nonbiological samples.

  • Analytical Services

    Our facility may accept contracts for analytical services from academic, commercial and government customers. All contract requests will be considered for feasibility by the facility staff and faculty. Please email with any questions regarding analytical services in the facility. 

    • Analytical and toxicological testing and validation services for target drugs using state of the art chromatographic and mass spectrometric techniques
    • A library of more than 1500 analytical standards for licit and illicit drugs, including NPS and metabolites
    • Screening, qualitative and quantitative analysis of therapeutic and pain management drugs and illicit substances in both biological and non-biological matrices
  • Instrumentation

    Our facility operates state-of-the-art analytical instrumentation applicable to research, training, routine and specialized analytical work and forensic case work. This instrumentation provides the facility with capabilities in robust and reliable ultra-trace analysis of drugs, analysis of toxicologic biomarkers, environmental pollutants, and natural products, in addition to the ability to conduct blood ethanol and volatiles analysis for forensic casework.

  • Rates

    Our facility has established a basic pricing structure for FIU faculty and staff who need to use the equipment in this facility. These are minimum fees required to keep the equipment running properly throughout the year. A separate rate structure applies to external users of the Facility.

    Pricing for internal clients can be found on the ORED website. Please contact with questions, scheduling and information on outside vendor pricing.

  • Facility Research

    Driven by the FIU and Global Forensic and Justice Center's (GFJC) research mission, our facility plays a key role in assisting faculty, graduate, and undergraduate students to conduct relevant research using state-of-the-art instrumentation and approaches.

    Strong educational support for the law enforcement agencies, academia and forensic laboratories is also provided in our facility. Workshops on modern forensic toxicology techniques, analytical instrumentation, data interpretation and customized method development strategies are offered per request.

    Research projects conducted at the facility under the direction of Dr. DeCaprio are focused on the development and application of analytical methods to enhance the value of scientific evidence in analytical and forensic toxicology. These projects have been supported by the National Institutes of Health, National Institute of Justice, private sector clients and other funding sources. Examples of past and ongoing research projects in the facility include:

    • Development of ultra-trace LC-QQQ-MS/MS and LC-QTOF-MS/MS methods for the comprehensive screening and confirmation of NPS, including phenethylamines, piperazines, tryptamines, and synthetic cannabinoids, in human specimen matrices such as blood, urine, hair, and oral fluid.
    • Systematic examination of the cross-reactivities of NPS with existing immunoassay screening platforms.
    • Application of in vitro drug metabolism assays to model in vivo metabolism of important drugs of abuse.
    • Development of new technologies for long term monitoring of human exposure to drugs of abuse and chemical warfare agents based on chemical modification of blood proteins.
    • Ultra-trace analysis of polychlorinated biphenyl and other persistent pollutant metabolites by dual-column GC and ECD.
    • Optimization of GC-EI-MS and GC-NCI-MS separation and analysis of abused prescription drugs, including benzodiazepines, hydrocodone and oxycodone, and their metabolites, in human hair and other biological matrices.
    • Evaluation of headspace GC with simultaneous FID and MS detection in blood alcohol and volatiles analysis.
    • Detection of nicotine and metabolites in the extracted blood of hookah smokers by online SPE and LC-QQQ-MS analysis.
    • Detection of organic compounds characteristic of gunshot residues by DART-MS.
    • Method development and analysis of methylphenidate and metabolites in oral fluid by LC-QQQ-MS.
