- In molecular exclusion (size exclusion) chromatography, the molecules have the longest retention times. a) the larger molecules b) the smaller moleculesA new method is proposed to simultaneously detectand separatefour foodadditives by reversed-phase liquid chromatography. The data were obtained using theliquid chromatographic column with a flow rate of 0.5 mL per min and with the followingparameters: Pore size 100 A Particle Size 3.5 Internal diameter 4.6 mm Length 150 mm The food additives found in the sample resulted in the following data: ( see image for table) a.Calculate the number of plates from each peak. b.Calculate the plate height for the column. c.Retention factor for each peak.Column Plate Number: 16Retention Factor: 3.1Sample Peak Retention Time: 1.2minutesSample Peak Width: 1.53First Peak Retention Factor: 2.10Second Peak Retention Factor: 1.37Efficiency: 0.43Pressure: 375barrColumn: 28cm x 5mmViscosity: 2.3poiseFlow Rate: 1.2Column Permeability: 2.8 FIND: a & ba.

- In analytical chemistry, when and why do we do representative sampling?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) An analyst has conducted a separation of a mixture of substance X and Y using liquid chromatography technique. The column used is 30-cm long and the flow rate was 0.65 mL/min. The chromatogram obtained is shown in Figure Q1.1. i) Determine the adjusted retention times for substance x and y. ii) Calculate the retention factors for substance x and y. iii) Calculate the resolution of the two peaks. Then, describe the quality of separation between the two adjacent peaks. iv) Calculate the plate height value of the column.
