Increase N - correct answers 1) Increase length of column 2) Optimize flow rate (Ux) to minimize H 3) Smaller packing bead diameter, uniform packing (A-term) 4) Thinner SP layer (less C term) 5) Open Tubular Liquid Chromo (No A) (A: more sensitive & resolution, fit more plate (N) shorter analysis D: small capacity) Absorption Chromatography - correct answers SP: Solid MP: Liquid or Gas Solutes move at different rates according to the forces of attraction to the stationary phase Parti...

You're using anion exchange chromatography to purify a small globular protein. After passing the mixture through the column, you find that your protein did not "stick" to the resin and flowed right through. What is a plausible reason for this to have occurred? Correct Answer-The pH of the solution is close to the isoelectric point. Oxygen binding that affects the cooperatively of hemoglobin is an example of heterotrophic regulation. Correct Answer-False You have determined that a leucin...

Extraction - correct answers Transfer of a solute from one phase to another Eluent - correct answers Fluid entering the column Partition Chromatography - correct answers Separation based on solute dissolving into stationary liquid Ion-Exchange Chromatography - correct answers Separation based on charge, stationary phase is made of either negatively or positively charged beads Size Exclusion Chromatography - correct answers Separation based on molecular size, larger molecules elute fi...
