ABSTRACT
The rise of monolithic stationary phases offers to routine and research laboratories several advantages. In spite of their recent discovery, they have rapidly become highly popular separation media for liquid chromatography. Time reduction and economic reasons like e.g. a diminished use of mobile phase are the most important ones. At the same time, it was reported that these columns offer a faster and better separation. The aim of this article was to investigate the transferability of methods originally developed on conventional particle-packed C(18) columns (XTerra RP18 and Zorbax RX), onto the more recent monolithic columns. Both types, conventional particle-packed and monolithic columns, were able to separate tetracycline, oxytetracycline and chlortetracycline from their respective impurities with sufficient resolution, but showed remarkably shorter analysis times and lower backpressures, improving the lifetime of the column.
