Semi-preparativE HPLC
Semi-Preparative HPLC for liquid chromatography
Semi-preparative HPLC has a modular design and is used for the purification of a wide variety of samples, such as peptides, organic syntheses, extracts, etc., by efficiently isolating target components down to the high milligram range.
Using very powerful software, this is achieved by simple and clear method development. For the processing of chromatograms complete data documentation according to GLP guidelines is included.
HPLC systems for semi-preparative chromatography consist of one HPLC pump with 2 double pistons, UV or UV/Vis detector, sample application system, fraction collector and the software for controlling the entire system as well as recording chromatograms.
The semi-preparative HPLC mainly fulfills two functions in the R&D laboratory. It is a link in upscaling analytical chromatographic methods to the preparative scale. With this semi-preparative HPLC, system parameters for upscaling can be determined easily and economically. Combined with the fraction collector, it is also used to obtain substances in the milligram range after analytical identification. The HPLC system for semi-preparative chromatography thus is an advanced analytical HPLC ensuring the user a successful transition into the preparative field.
