Instrumental Investigations: A Laboratory Manual of Forensic Analytical Chemistry
Poster Apr 01, 2016
Robert Q. Thompson
The laboratory manual describes 25 instrumental analysis experiments for undergraduates, covering 13 chapters and 270 pages. The experiments closely approximate those performed in actual crime labs. Included with the book is a flash drive holding student procedures in MS Word format, allowing editing, conversion to PDF files, and posting on your course site.
Each experiment in the manual comes with up-to-date references, helpful instructor notes, and expected data and results. All the information one needs to set up the experiment and to make sure it works in an undergraduate lab is here.
As a vehicle to combine several experiments into an end-of-semester project, crime scenarios are provided with a list of expected analyses, names of suspects, police reports, witness statements, etc. An example is the Case of the Pilfered Painting that involves artists’ oil paint, glass, documents, gunshot residue, drug evidence, and a crime scene inside an art museum.

Fundamentals and Comparisons for Organic Sample Extract EvaporationPoster
Sample preparation is a key step in the analysis process
Parameters for evaporation and their impact on analysis have been discussed
Improvements in matching the sample to the evaporation device characteristics can help reduce variability and improve recovery
Examples for choosing a system based on sample volume, types of analytes, sample load, and initial investment considerations
Using Elemental Analysis For Discrimination Of Pinot Noir Wines From Six Different Districts In An AvaPoster
The determination of geographical origin of wine is gaining increased interest by researchers and federal agencies around the world, partially due to increased fraud with regards to place of origin labelling. For wine, multi-elemental profiling of macro, micro, and trace elements has been proposed for determination of authenticity. Commercial wines from different wineries in 5 different neighborhoods within one AVA show characteristic elemental fingerprints. Macro, micro and trace elements as well as elemental ratios contribute to the observed separation, indicating the involvement of multiple factors and underlying mechanisms, including location and soil composition, elemental uptake by vine and rootstock, viticulture and nutrient management, water sources, and small differences in the different wineries.READ MORE
