Organic Analysis Discussion

Your day in the Forensic Lab had been fairly routine. Around 1:00pm, an investigator drops off some items of evidence to be analyzed from the scene of a homicide. One is a brown gummy substance found at the crime scene, another is an ink pen and note with writing, and the final is an unknown white powder. With each question, your substantial post should have at minimum 5 to 6 sentences for each question and for each of the different pieces of evidence.

For each item of evidence discuss the following:
1) Which analytical method/equipment would you use?
2) Why would you use this particular method for that piece of evidence?
3) How does that method/equipment work? Give details about how the method works.

Answer:

1) The brown gummy would be going through a Food & Beverage. The ink pen and note would be going through Chromatography. The white powder would be going through Qualitative analysis. 

2) The gummy would be tested for food safety, nutrition, and quality. The ink pen would be tested for separating a mixture of chemical substances into its individual components. The white powder would be tested for a reaction.

3) The method would work for the brown gummy to see why it's brown, how long has it been sitting out, and is there any connection to the case. The method would work for the ink pen and note so it can be thoroughly analyzed to see if it was written in a distressing or frightening matter. The method for white powder would work to determine if it's narcotics or just baking powder.
