Substances A, B, C and D were found to have retention times of 8.3 min (A), 10.6 min (B), 12.4 min (C) and 13.5 min (D), respectively on an 15.0 cm long column. There was also an unretained species which appeared at 1.5 min. The widths of the peak bases were 0.90 min (A), 1.1 min (B), 1.3 min (C) and 0.80 min (D). Given this information listed above, please choose the most appropriate answer for the six questions listed below for the list of possible answers. Part A Calculate the capacity factor (k') for peak B and peak D. Part B. Calculate the resolution (R) between peaks B and D. Part C. What do the capacity factor and resolution tell you about the separation of peaks B and D on this column? Part D What are the theoretical plate number (N) for peaks Band D? Part E. What is the average plate height (H), based on the information in Part D and the column length listed above? Part F What would be the required length of a column to achieve a Rs of 2.07
Select wether the following statements are True or False: Two compounds that are separated on a 10 cm column have a resolution equal to 1.5. If all conditions remain identical, if the length of the column is doubled, the resolution will increase. An example of a stationary phase support used in strong anion exchange would be a quarternary ammonium-functionalized polymer. In normal phase chromatography, a more polar compound will have a higher partition coefficient than a compound that is less polar. In gas chromatography, compound with higher boiling points generally (but not necessarily) elute later than compounds with lower boiling points. In a chromatographic separation, a compound with a capacity factor equal to 1 must spend an equal amount of time in the mobile phase as it does in the stationary phase.
2. To determine the concentration of analyte in a sample a standard additions was performed. A 5.00-mL portion of sample was analyzed and then successive 0.10-mL spikes of 1 600.0- mg/L standard of the analyte were added, analyzing after each spike. The following table shows the results of this analysis. Vspike, mL Signal intensity 0.00 0.119 0.10 0.231 0.20 0.339 0.30 0.442 Construct the calibration curve, calculate the linear least-squares equation for the data and determine the concentration of analyte in the original sample.
Chloroform is an internal standard in the determination of the pesticide DDT in a polarographic analysis in which each compound is reduced at an electrode surface. A mixture containing 0.500 mM chloroform and 0.800 mM DDT gave signals of 15.3 µA for chloroform and 10.1 µA for DDT. An unknown solution (10.00 mL) containing DDT was placed in a 100-ml volumetric flask and 10.2 ul of chloroform (MW = 119.39, density = 1.484 g/mL) were added. After dilution to the mark with solvent, polarographic signals of 29.4 and 8.7 µA were observed for the chloroform and DDT, respectively. Find the concentration of DDT in the unknown.
Classify the descriptions based on whether they apply to ion‑exchange, size‑exclusion, or both types of chromatography columns. - Proteins move through the column at rates determined by their net charge. - The gel bed will contain polymer beads with charged functional groups. - Proteins move through the column at rates determined by their size. - The gel bed will contain porous polymer beads. - The properties of the proteins affect the rate at which they migrate. - Proteins are separated based on differences in their amino acid sequences.
The following results were obtained for the determination of calcium in a NIST limestone sample: %CaO = 50.33, 50.22, 50.36, 50.21, and 50.44. Five gross samples were then obtained for a carload of limestone. The average %CaO values for the gross samples were found to be 49.53, 50.12, 49.60, 49.87, and 50.49. Calculate the relative standard deviation associated with the sampling step
The following statements are true for any chromatographic analysis except: The analyte component interacting most strongly with the stationary phase elute faster than those with weaker interactions. On the other hand, those with least interaction with the mobile phase elute the slowest. Interactions between mobile phase-analyte - stationary phase can be both chemical and physical in nature.
