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 [...]

What is chromatography?

Scheme of chromatography

Chromatography is analytical chemistry method which is used (and useful) for the separation of complex mixtures of chemical compounds. The main mechanism of the separation is repeatable distribution of the tested compound in between two different phases. Usually, one phase is solid, fixed in the separation device and the other is moving and flows through [...]
