QUESTION 16 Which of the following is INCORRECT concerning "fronting" in chromatographic peaks? the front of the peak has a gradually increasing concentration OA. is seen as a gradual rise and then an abrupt fall of the chromatographic peak B. O C. can be reduced through silanization of the silica sites on the column D. occurs due to overloading of the column occurs because the stationary phase begins to resemble to solute E.

Retention time is the time taken for the mobile phase to reach the detector. True False
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.

None
Which statement regarding the techniques utilzed in splitless injection for gas chromatographic analysis is NOT true? Select one a. Solvent trapping and cold trapping sharpen the peaks for all components, including the solvent and solutes. b.Cryogenic focusing is required, with an initial column temperature below room temperature, for low boilling Oc In solvent trapping, the Initial column temperature is set 10-20°C below the bolling point of the solvent. d. In cold trapping, the initial column temperature is at least 100°C below the boiling points of the solute of interest. e. In solvent trapping. both solvent and solutes are condensed at the column head.
