6-Aminoquinolyl-N-hydroxysuccinimidyl carbamate is a well-known reagent used to derivatize amino acids (AAs) into their aminoquinolyl carbamate (AQC) analogs. Originally, AQC derivatization was used to enhance UV detection of amino acids (and amines)

Supercritical fluid chromatography is becoming more prevalent, particularly in industry. This is due to the inexpensive, and more importantly, environmentally benign carbon dioxide that is used as the major component of the mobile phase. Water is min

Supercritical and near supercritical fluids are considered green solvents of the future because they decrease the need for toxic organic solvents and are easily recyclable. Consequently, supercritical fluid chromatography, SFC, has emerged as an envi

More than 40 cosolvents have been used with carbon dioxide to alter its solvation strength. Among the most interesting systems is the subcritical/supercritical CO2/alkanol eluents. Using small amounts of water in CO2/MeOH is known to be beneficial in

Core-shell particles (superficially porous particles, SPPs) have been proven to provide high-throughput and effective separations of a variety of chiral molecules. However, due to their limited commercialization, many separations have not been report
