Polar compounds were separated by HPLC using a bonded phase containing polar diol substituent [-CH(OH)CH,OH]. How would the retention times be affected if the eluent were changed from 70 vol.% to 30 vol.% of acetonitrile in water? Retention times will be unchanged. Retention times will be shorter Retention times will be longer D Changes in retention times are not sure.

An unknown compound was analyzed by GC with octane (C3H18) and decane (C10H22). The adjusted retention times were 14.6 min for octane, and 31.6 min for decane. Calculate the retention index for the unknown if its adjusted retention time was 21.2 min.
What is the retention factor of a sample when after injectiion the void time (tM) took 4.18 sec? The retention time (TR) is 21.19 sec
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
In the table below, record the color that you observe for each spot or component of each spot after the run is completed. For the retention factor, R₁, write in the numerator (top) the number of mm that the spot has moved and in the denominator (bottom) the number of mm that the solvent has moved from the point where the samples were 'spotted. Calculate the Rf vale for each spot or component of each spot. Im having a difficult time finding the Retention Factor for M&Ms by using Salt water and seeing how much each color moves Instructions Coffee filters usually are round, but it's easier to compare your results if the paper is rectangular. So, your first task is to cut the coffee filter into a rectangle. Measure and cut a 2-3/4" by 7" strip from the middle of a coffee filter. This is easily done by folding the filter in half (to make a half-circle) and then folding the half-circle into thirds. Cut along the 13-fold lines and trim the ends to make a rectangle. 2.

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?

You must separate three different compounds with reversed phase HPLC. Compound 1 is an acid (pKa = 4.3), compound 2 is neutral compounds and compound 3 is a base (pKa = 9.6). As eluent, use 30/70 (v / v)% methanol / pH 3.0 formic acid buffer. The retention time and the top width at the base of the top for the three components are presented below. You can assume the dead time to 1.2 minutes in your calculations.Compound Retention time [minutes] Peak width [seconds] 1 10.1 282 5.0 143 6.1 17a) Calculate the efficiency (number of theoretical bases) for component 1.b) Calculate the selectivity and resolution between components 1 and 2.c) When you increase the pH of your eluent to pH 6, how will the retention be affected (increase, decreaseor unchanged) for the different associations (1, 2 and 3) ?, justify your answer.d) How retention factors are generally affected by an increase in the proportion organicallymobile phase solvents for reversed phase HPLC separations ?, justify your…
