In the present study, a novel poly(acrylamide‐co‐N‐isopropylacrylamide‐co‐ethylene dimethacrylate) monolithic column modified with saline‐modified delaminated layered double hydroxides was developed and exploited as the stationary phase in the polymer monolith microextraction of β‐agonists. Transmission electron microscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, X‐ray...
Porous monoliths are well‐known stationary phases in high‐performance liquid chromatography and capillary electrochromatography. Contrastingly, their use in other types of separation methods such as gas or supercritical fluid chromatography is limited and scarce. In particular, very few studies address the use of monolithic columns in supercritical fluid chromatography. These are limited to silica‐based...
