In order to obtain better and faster separation, instruments using higher pressures than common HPLC have been developed. These are often referred to as ultra-high-pressure liquid chromatographs (UPHPLC), or some similar abbreviation. They are used in a manner similar to HPLC and can be connected to mass spectrometers.

For enhanced throughput, fast RPLC methods using monolithic silica columns [238], small size particles (3 pm) packed columns [173, 195, 226, 235-237, 239, 240], ultra high pressure liquid chromatography (UHPLC) columns packed with sub-2 pm particles [145,196, 227, 245, 247] and 2.6 pm core-shell particles HPLC columns [246] have been proposed for the high-throughput separation and quantification of tamoxifen/metabolites.

The development of ultra high-pressure liquid chromatography technology has dramatically reduced the analysis time for a number of small molecules. However, we have found that the analysis of carotenes is poor with the currently available column chemistries. The development of C30 columns with backbones that can withstand ultra high pressure would allow carotenoid chemists to take full advantage of this technology. [Pg.135]

The use of LC with conventional LC columns (5 jm) is a common and well-established technique in food analysis. However, the limitations of the use of this type of column do not solve all analytical problems. This fact is especially critical in food metabolomics because of the complexity of food matrices and the high number of compounds of interest. Therefore, the use of ultra-high-pressure liquid chromatography (UHPLC) can overcome the limitations of conventional LC, providing... [Pg.52]
