Use of Fortis HILIC Stationary Phases
20 Sept 2011This application note shows the mechanisms and considerations that are important to those requiring the HILIC method of chromatography in order to retain the more polar analytes that can cause issues in retention and separation. The correct use of HILIC column can provide additional selectivity and resolution, especially for hydrophilic analytes.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

This can be done in large quantities or small. Preparative chromatography systems are usually low to medium pressure liquid chromatographs that are semi-automated. Explore a range of preparative columns and fraction collectors.

Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
