TL;DR: In this article, the retention behavior of carboxylic acids in reversed-phase and reversed phase ion-pair choromatography on hydrophobic alkyl-modified silica gel was investigated.

TL;DR: In this article, the authors compared three types of liquid chromatographic detectors: tubular, packed bed and gas-segmented liquid flow systems, and gave some specific instrumental problems (mixing, noise level) for optimal design.

TL;DR: In this paper, the rentention behavior of a series of amines and amino acids was studied in systems consisting of a hydrophobic column packing and water or water−propanol mixtures containing low concentrations of alkylsulphonates of increasing chain length as the mobile phase.

TL;DR: In this paper, the retention behavior of a series of amines was investigated in phase systems consisting of an alkyl-modified silica as column packing material and an aqueous buffer or buffer-propanol mixtures containing low concentrations of alkylsulphonates as the mobile phase.

TL;DR: In this article, the authors show that the pressure drop over a packed-bed reactor is lower than over a coiled open tubular reactor, and that for a given residence time and equal band-broadening values, the pressure drops over a PBR are lower than those of a COTR.
