2. Consider the following example GC Chromatogram from a publication about aggression among
Mediterranean Acrobat Ants (C. scutellaris). This particular sample was generated by rinsing
hydrocarbons from ant exoskeletons. From the chromatogram, what is the minimum number of
unique compunds present in the sample? What data led you to that conclusion?

Anna analyzed arsenic content on a fish purchased from local wet market. According to
Food Regulation 1985, permissible level for arsenic in fish and fishery product is 1 ppm.
In this study, an average of 11.4 2.1 ng/g was obtained based on six sample replicates.
Suggest a suitable analytical instrument to be used in this analysis and draw a conclusion
on the safety of arsenic content of this fish sample.

- You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer?

- A controversy broke out as a dead body was found in a bar on Cornelia Street. The media revealed that minutes before the person died, he described his drink as something stronger than other drinks in the bar. You were the analyst tasked to verify the cause of death. Preliminary qualitative tests showed the possible presence of cyanide in the victim's death. Thus, you tried to quantitatively detect cyanide ions in the victim's drink using spectrophotometric analysis. Standard solutions were of different CN- concentrations were made as shown in Table 2. A 25.0mL aliquot of each standard solution was added with Fe(NO3)3 to form the colored complex, [Fe(CN)6]³ (aq). Each standard solution was then diluted to a total volume of 50.0 mL. The absorbances of the diluted standard solutions were recorded using 1.00-cm cells and at Amax = 725 nm and found in Table 2. Table 2. Raw absorbance measurements for each standard solution of CN-.
