The same polar compound is gas chromatographed on an SE-30 (very nonpolar) column and then on a Carbowax 20M (very polar column). I low will K=cS/cM vary between the two columns?
Retention times with a 1.10 m gas-liquid chromatographic column: air, 18.0 s; methyl acetate, 1.98 min.; methyl propionate, 2.24 min; methyl n-butyrate, 7.93 min.Base widths of the last three peaks: 0.19; 0.23 and 0.79 min, respectively. Calculate:a) the value of k for each compound,b) the alpha value for each pair of adjacent peaks,c) the theoretical number of plates and the plate height of each column;d) the resolution of every two adjacent compounds.
Thin Layer Chromatography why the non-polar compounds move up the plate most rapidly (higher Rf value), whereas polar substances travel up the TLC plate slowly or not at all (lower Rf value)? Please help me explain this question! Thank you so much!
Two components in an HPLC separation have retention times thatdiffer by 22 s. The first peak elutes in 10.5 min and the peakwidths are approximately equal. Use a spreadsheet to find theminimum number of theoretical plates needed to achieve thefollowing resolution, Rs, values: 0.50, 0.75, 0.90, 1.0, 1.10, 1.25,1.50, 1.75, 2.0, and 2.5. How would the results change if peak 2were twice as broad as peak 1?
A mixture of biphenyl, benzyl alcohol, and benzoic acid is spotted on a silica gel TLC plate and developed using Ethyl Acetate with 0.5% acetic acid as the solvent. Predict the relative Rf (highest to lowest).
In a normal phase chromatography set up, the component that yields the highest Rf value is likely to be _____. Group of answer choices Both polarity Cannot be determined Polar Non-polar
Two compounds A and B from GC on two open tubular columns contains a XY-1 (100% methyl) and a XY-2 (50% methyl, 50% phenyl), with the same diameter, thickness and length under the same experimental conditions. The retention times and peak widths are show in the Table 1.Hint: phenyl groups interact more strongly with polar groups than methyl groups. Which compound is more polar? Explain your answer
A series of nonpolar aromatic compounds were separated by isocratic HPLC on a nonpolar stationary phase containing octadecyl groups [−(CH2)17CH3] covalently attached to silica particles. The mobile phase was 60/40 methanol/water. How would the retention times be affected if 90/10 methanol/water were used instead and why? What type of chromatography?
Z and E -oct-3-en-2-ol is hard or easy to separate in thin layers in chromatography?

in what order (from lowest to highest Rf) would you expect to find compund A, B, and C on a silica gel TLC plate with dichloromethane? Draw flowchart for separation with org solvent: ether, methylene chloride, aq: HCl, NaOH, NaHCO3
In order to obtain better separation of the mixture, the above analysis was repeated using an HPLC technique. The retention times of compounds A and B were found to be 15.25 and 16.80 min, respectively, on a 40-cm packed column. An unretained species passed through the column in 1.25 min. The peak base width for A and B are 1.15 and 1.27 min, respectively. Calculate: i) The column resolution. ii) The average number of plates in the column. iii) The plate height. iv) The length of column required to achieve a resolution of 1.5.
