- From the data in Problem 26-14, calculate for species C and D) (a) the resolution. (b) the length of column necessary to separate the two species with a resolution of 2.5.arrow_forwardI need the theoretical molar extinction coefficient of paranitrophenol in mol^-1cm^-1 (using moles not μM). I have to calculate the % difference.At the experimental level it was 7,200 mol^-1cm^-1arrow_forwardExactly 5.00 mL aliquots of a solution containing analyte X were transferred into 50.00-mL volumetric flasks and the pH of the solution is adjusted to 9.0. The following volumes of a standard solution containing 2.00 µg/mL of X were then added into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50 and 2.00 mL. The fluorescence of each of these solutions was measured with a fluorometer, and the following values were obtained: 3.26, 4.80, 6.42, 8.02 and 9.56, respectively. ii. Using relevant functions in Excel, derive a least-squares equation for the data, and use the parameters of this equation to find the concentration of the phenobarbital in the unknown solution.arrow_forward
- A molecular exclusion column has a diameter of 7.8 mm and a length of 30 cm. The solid portion of the particles occupies 20% of the volume, the pores occupy 40%, and the volume between particles occupies 40%. (a) At what volume would totally excluded molecules be expected to emerge? (b) At what volume would the smallest molecules be expected? (c) A mixture of polymers of various molecular masses is eluted between 23 and 27 mL. What does this imply about the retention mechanism for these solutes on the column?arrow_forwardSubstances A and B have retention times of 16.4 and 17.63 min, respectively, on a 30 cm column. An unretained species passes through the column in 1.3 min. The peak width at base for A and B are 1.11 and 1.21 min, respectively. Calculate:arrow_forwardA Dubosq colorimeter consists of a cell of fixed path length and a cell of variable path length. By adjusting the length of the latter until the transmission through the two cells is the same. the concentration of the second solution can be inferred from that of the former. Suppose that a plantdye of concentration 25 μg dm-3 is added to the fixed cell. the length of which is 1.55 em. Then a solution of the same dye. but of unknown concentration. is added to the second cel l. It is found that the same t ransmittance is obtained when the length of the second cel l is adjusted to 1.18 em. What is the concentration of the second solution?arrow_forward

- (a) Three components in a mixture have varying distribution constants between the mobile phase and the stationary phase. One of the components has a very high distribution constant. Would this component likely elute first or last and how would you design an experiment or modify the components of the separation to make it perform in the opposite manner? (b) One way to dramatically increase the sensitivity of a quadrupole mass spectrometer is to use a technique called selected ion monitoring (SIM). Explain how this technique works and why it improves sensitivity. Explain what dwell time means. Be sure to draw a diagram and describe how this analysis scheme works. Also, is there a compromise between a wide range of masses scanned and SIM?
