The following Rf values were computed from a normal phase chromatography experiment. Arrange them from most polar to least polar. I - 0.25 II - 0.84 III - 0.56 IV- 0.67 Group of answer choices II > IV > III > I I > III > IV > II I > II > III > IV IV > II > III > I
Which statements are true for molecular exclusion chromatography?I Molecular exclusion chromatography separates on the basis of size.II Small molecules can fit in the pores of the stationary phase and effectively pass through a larger volume, and elute last.III The pores in the stationary phase are too small for large molecules to pass through, so large molecules elute first.IV Molecular exclusion chromatography with a hydrophilic stationary phase and an aqueous solvent is called gel permeation chromatography.

Paper Chromatography Calculate the Rf for a spot that travels 2.41 cm from the baseline while the solvent travels 7.85 cm from the baseline. Answer with the number; there are no units for Rf I got the answer: 0.3070063694267516 2.41/7.85 = 0.3070063694267516 just wanted to make sure.
Thin‑layer chromatography (TLC) can be used as a preliminary identification method for many amphetamine‑type stimulants (ATS). Using a 0.25 mm thick silica gel stationary phase and a 98.5:1.5 methanol:concentrated ammonia mobile phase, a spot was observed to have traveled 3.52 cm when the solvent front traveled 8.81 cm. What is the retardation factor (?F)for the compound that composes this spot?

The figure below shows a typical separation of several fat-soluble vitamins by HPLC. The x-axis is retention time in minutes. From the graph try to estimate retention times for peaks 2 and 3. Retention time peak 2 = Retention time peak 3 = Assume that w1/2 is 0.15 minutes for peak 2 and 0.16 minutes for peak 3. Assume that tm is 2.00 minutes. How much time does gamma-tocopherol spend in the stationary phase? From tr and w1/2 find N for the peak that elutes first. From tr and w1/2 find the resolution of peaks 2 and 3 Calculate α for these peaks. If the flow rate for the column is 1.2 mL/minute what is the retention volume for peak 4?
