The image shows chromatograms for the separation of compounds A and B obtained at the same flow rate from two different columns of equal length. The void time, tm, is equal to 1.75 min on each column. Column 1 Detector Response Column 2 5 15 20 25 - 10 Time (min) — What is the value of the unadjusted relative retention, y, for the two compounds separated using column 2? y =

10000 page 6 9.10 Two chromatograms are shown. Both chromatograms show the separation of the same mixture using the same chromatography column with the same flow rate, but under different conditions Chromatogram #1 Chromatogram #2 compound (a) If the chromatograms were obtained by gas chromatography, which one used the higher column temperature? Explain briefly, showing that you understand the effect of temperature on retention in gas chromatography (b) If the chromatograms were obtained by liquid chromatography, which one used the...

2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
