A mixture of species of A, B, and C is injected into a liquid chromatographic column with length of 20.0 cm. The obtained separation results are listed as follows: Please calculate the resolution for species B and C from the data. Please keep your result to two decimal places. The answer would be 1.22, I would need help how to get that answer

The data in the following table were extracted from a gas chromatographic analysis of a two- component mixture. Air nonane decane Retention time (s) 5 26 32 Peak width, baseline (s) 5 4 (i) Calculate the capacity factor, k, for the two compounds. (ii) Calculate the selectivity factor, a, for the two compounds.

You run the chromatography system with paper as the stationary phase and 70% isopropanol as the mobile phase. You determine the Rf  of a polar analyte to be 0.40. If you use 100% isopropanol (a less polar solvent) instead of isopropanol as the mobile phase what would you expect to happen to the Rf  value? No value effect on Rf higher  lower could be higher or lower

For quantitative analysis with gas chromatography: O the area of a peak reported by the instrument for a compound is proportional to the quantity of that compound. O the calculated response factor value for a compound is proportional to the quantity of that compound. O the retention time reported by the instrument for a compound is proportional to the quantity of that compound. O the peak height reported by the instrument for a compound is inversely proportional to the quantity of that compound. O the peak shape reported by the instrument for a compound is proportional to the quantity of that compound.
