1 Mass Spectrometry in Forensic Science Erin Shonsey January 29, 2010 Overview Introduction to forensic sciences Uses of mass spectrometry in forensic sciences Typical instrumentation in forensic sciences Applications of new instrumentation 1
2 Introduction to Forensic Sciences Forensic Sciences is defined as: the application of a broad spectrum of sciences to answer questions of interest to the legal system. Introduction to Forensic Sciences Typical analytical sections within a forensic science laboratory: Drug Chemistry Analysis of pills, powders, liquids, plant materials, and other suspicious items for illegal drug content Toxicology Analysis of biological samples for alcohol, prescription medication, drugs of abuse, and other chemicals that are not naturally occurring in the body DNA Extraction and amplification of DNA from biological fluids for identification Firearms Bullet pattern recognition and analysis of gun powder Fire Debris -- Identification of ignitable liquids used in arsons 2
3 Standards for Accepting the Scientific Validity of a Procedure, Technique, and Principle Alabama Frye standard: the court must decide if the questioned procedure, technique, and principles are generally accepted by a relevant community Federal Rule 702: a witness qualified as an expert may testify in the form of an opinion Federal Daubert: Has it been tested? Has it been published and peer reviewed? Potential rate of error Existence and maintenance of standards controlling the techniques operation Accepted in the relevant scientific community Mass Spectrometry in Forensic Science A gas chromatograph with a mass spec detector is the final tool used in the analysis of drug chemistry and toxicology samples for identification and confirmation. 3
4 Typical forms of Mass Spectrometry in Every Forensic Science Lab Gas Chromatography-Mass Spectrometry (GC-MS) Typical forms of Mass Spectrometry in Every Forensic Science Lab Gas Chromatography-Mass Spectrometry (GC-MS) 4
5 Typical forms of Mass Spectrometry in Gas Chromatography-Mass Every Forensic Science Spectrometry Lab(GC-MS) Spectrum Typical forms of Mass Spectrometry in Every Forensic Science Lab Gas Chromatography-Mass Spectrometry (GC-MS) Spectrum Spectra are searched against a library of known compounds in an effort to identify every peak in the TIC A standard is analyzed on the instrument to generate a known retention time and spectrum of the compound for that instrument 5
6 Problems Encountered with the GC/MS Lose the parent ion of the compound upon ionization in the instrument Example: Methadone Problems Encountered with the GC/MS Derivatize the compound for analysis with GC/MS which decreases detection of low level compounds Example: THC 6
7 Problems Encountered with the GC/MS Heat labile compound will be identified as a related compound, but not the actual compound Example: Clorazepate to Nordiazepam New Technology Four new instruments have been brought into the department in October 2008 AccuTOF-DART mass spectrometer 3200 QTRAP mass spectrometer with LC 3200 QTRAP mass spectrometer with DART HS-GC-MSD 7
8 Different forms of Mass Spectrometry Liquid Chromatography Electrospray Ionization Mass Spectrometry (LC-ESI-MS) Sample solution Gas -5 KV Atmospheric pressure N 2 Collision gas Q1 Q2 Q3 Detector Vacuum Different forms of Mass Spectrometry Direct Analysis in Real Time with Time of Flight Mass Spectrometry N 2 TOF detector Electrostatic reflector 8
9 HS-GC-MSD This instrument provides opportunity for qualitative and quantitative identification of volatile compounds TIC of Volatiles Mix 9
10 Spectrum of Peak at 1.44 min Isopropanol Spectrum of Peak at 1.61 min Acetone 10
11 Spectrum of Peak at 1.70 min 1-propanol (IS) TIC of Ethanol Standard 11
12 Spectrum of Peak at 1.29 min Ethanol Spectrum of Peak at 1.70 min 1-propanol (IS) 12
13 Summary Method development is underway with the HS-GC-MSD Good separation and spectra from the volatiles mix and ethanol standard Ready to start validation Developing method for commonly abused inhalants Developing a screening for other volatile compounds Example: GHB AccuTOF-DART MS The DART is the first open air, ambient ion source for a mass spectrometer Coupled to a time of flight instrument exact mass measurements can be used in the putative identification of compounds 13
14 3200 QTRAP-DART MS Coupled to a hybrid triple quadrupole/trap instrument molecular ions can be individually fragmented for identification of sample components DART Ionization Penning ionization: energy is transferred from metastable ions (M*) Positive ions: He* ionizes water which transfers a proton to the sample Negative ions: Penning electrons are rapidly thermalized and captured by oxygen which ionizes the sample onmechanisms/tabid/450/default.aspx 14
