in the separation of these 8 organic herbicides using HPLC in two different modes: Isocratic elution and gradient elutions. Stationary phase is C18 and the eluent is water-acetonitril (ACN) mixture as presneted in the figure. Rate is the same (1ml/min, Temperature is the same 35 C). i) Compare both the isocratic elution and gradient elution in this experiment. ii) explain why component 8 comes at 30 min in gradient elution without peak tailing while it appears at ~ 65 min in isocratic elution as shoeter and wider peak with tailing.

Extraction of Caffeine Post-lab 4. What does it mean for two solvents to be immiscible? 5. On the report sheet, you calculated your percent recovery of caffeine. a. If your percent was less than 90%, give at least one reason why it was less. b. A group of students have their percent yield more than 100%, give at least one reasonwhy it was more than 100%. Do NOT simply say “human error.” Be specific about the typesof errors (human or otherwise) that may have occurred, leading to a recovery more than eorequal to 100% (Is this possible Why?) 6. Based on what you observed during this experiment, is dichloromethane denser OR lessdense than water? Explain your reasoning. 7.
