Writing for publication

Berkeley Lab organized yesterday short workshop focusing on writing for scientific journals. The workshop took 2 hours and it was mainly focused on the “schedule” we should follow during the publication preparation. The first part summarized the journal selection. I will not go to much details here, because we probably already know in which journals [...]

Column permeability

Column permeability calculation

One of the most important characteristics describing the column properties is column permeability. Term permeability refers to the column packed with a stationary phase (particles or monolith) and describes how easy flows the liquid (mobile phase) through the column. At given pressure, the higher is flow through the column the higher is the permeability of [...]

Separation of small molecules with organic polymer monolith

Because of lack of small pores it is difficult to separate small molecules with polymer monoliths in isocratic mode. We have prepared monolithic capillary columns and then hypercrosslinked them to afford a monolith containing an array of small pores [1]. This monolithic column affords good separation of uracil and alkylbenzenes in isocratic mobile phase mode [...]
