5. The following are short answer questions concerning chromatography. a. b. C. 2 In GC, you learned that H₂ gas has some advantages over using He gas. What are two advantages? If you are using uv/vis absorption to detect analytes coming off a chromatography column, why are you more likely to measure peak area that peak height when making a graph of signal versus concentrations for the standards? The van Deemter equation can be written as: H = A + B/u + Cu Give brief explanations for the A, B, and C terms. Be sure to explain how each term is affected by the flow rate of the mobile phase.
