Background (Relates to question 1,2, and 3): After graduation from Butler you decided to pursue a career in forensic science. After going on in school and completing a masters in forensics at Michigan State University, you are hired by the Indiana State Forensics lab as their analytical chemist. Your lab is equipped with the following instruments: A. Thermo Q-Exactive LC/MS, which is a quadrupole-orbitrap hybrid instrument with a liquid phase chromatography inlet and both electrospray and atmospheric pressure chemical ionization (APCI) sources. - Cost $450,000 B. An Agilent gas chromatography / mass selective detector (GC/MSD) with a quadrupole mass analyzer, a GC inlet, and both electron ionization (El) and chemical ionization (methane CI) modes. This instrument is also configured with the full Wiley (El) library of pesticides and drugs. - Cost $80,000 C. A Bruker Ultraflex Matrix-Assisted Time-of-Flight (MALDI/TOF) instrument capable of MALDI ionization capable of linear, reflectron, and MS/MS mass analysis using MALDI ionization. - Cost $400,000 D. A Sciex 5500 triple-quadrupole (QQQ) with a Shimadzu ultra performance liquid chromatography (UPLC) inlet and both electrospray and atmospheric pressure chemical ionization (APCI) sources. Cost $350,000 Your first week on the job, you are called in to support a team investigating the death of a homeless person under suspicious circumstances. The body arrives in the morgue and you are asked to try to determine the cause of death. You are sent blood, plasma, and urine samples for analysis. Question 2. You are able to obtain accurate MS and MS/MS electrospray spectra on the unknown. Apply the approach we discussed in the 'interpretation of mass spectra' lecture to identify the unknown. Explain in detail how you worked through each step of the Interpretation: A General Protocol procedure to justify your assignment of the unknown using the spectra shown below.
