ultrafiltration on the mass-transfer efficiency improvement in a
pararell-plate countercurrent dialysis system.
what is the effect of air flowrate and stirrer speed on oxygen mass
transfer in an aerobic process?
What are the potential impacts this might have on an
industrial scale?
and how can the condition be improved?
Smaller particles affect HPLC column efficiency in what
ways?
A)increase the mass transfer term.
B)diminish the pressure constraints of the mobile phase.
C)reduce stationary phase retention
D)enable lower slopes inthe C term
E)cause higher temperature as a result of increased frictional
heating.
Gradient elution used in HPLC. How is the gradient created for a
reverse-phase HPLC experiment over the course of the run?
