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? Explain the basis for your decision.
The aspirin we made in lab gad 125-133 melting point and I attached the IR. Base on this information, does it mean we made aspirin? The percent yield was also less than 50. Is that acceptable? Is this aspirin pure or not? please explain your answer.
