Expert help when you need it- Q1: 5. Which of these particle diagrams represents a sample of pure water? How can you tell? See Answer
- Q2:Need help with this homework which is 6 summaries of 6 analytic chemistry journal readings from the American Chemical Society (ACS). For each summaries, only a paragraph is needed, like 250 words each. It has to be Analytical Chemistry journals. Here are the link: https://pubs.acs.org/action/showMostReadArticles? topArticlesType=recent&journalCode=ancham Choose any 6 articles from the above link and work on this assignmentSee Answer
- Q3:Question 2 a) You work for an environmental laboratory conducting screening of wastewater for potential contaminants. The laboratory currently possesses a reverse-phase liquid chromatograph but is considering purchase of an ion chromatograph. Provide an argument for the laboratory's procurement officer that purchasing an ion chromatograph would extend the laboratory's analytical capabilities. Your answer should make use of appropriate annotated diagrams. b) You are an analytical chemist in a forensic laboratory. You have been tasked with analysing fire debris for volatile hydrocarbons that might be indicative of a chemical accelerant. i. Which mode of chromatography would you recommend for this purpose, and why? Justify your answer. ii. The evidence submitted is a swatch of carpet in a sealed container. How would you sample potential volatile hydrocarbons from this material? Justify your approach. c) Using media or internet sources, identify and describe a "real-world" problem in which gas chromatography, liquid chromatography, or ion chromatography was used to achieve separation of analytes in a mixture.
