Which among the following applies to reversed phase chromatography? i. Compounds of low polarity will result to low retention factors. ii. Polar compounds will interact better with the stationary phase than with the mobile phase iii. Using non-polar solvents will hasten the rate of separation of the components in the sample

In the second paragraph you should define and describe the process of gas chromatography. In this paragraph answer the following questions: a) Why might it be necessary to dilute the sample? Approximately how much sample is used? b) Describe good injection technique. What sort of syringe is used in gas chromatography? c) What property of compounds will make the retention time longer or shorter? Use as an example ethyl acetate, propyl acetate, and butyl acetate, since these compounds are the ones we are studying in this experiment. d) What are a few different types of detectors and how do they work?
