Two commonly used chromatography methods in labs are Nickel and streptavidin resin based colums. Explain which type of chromatography-ion exchange, size-exclusion, or affinity-these are, as well as their seperation mechanisms at a molecular level.
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.
With reference to the Van Deemter equation, explain thoroughly whether separation may be expected to improve in an LSC column with a 5 μm particle size or the one with a 20 μm particle size
