Product news

Merck KGaA is one of the market leaders in HPLC and has a clear committment to the further development of sorbents, analytical and preparative HPLC columns. The particulate HPLC products LiChroprep®, LiChrospher®, Purospher®, Pharmprep® are most widely used in analytical or preparative applications. The analytical Purospher® STAR columns provide excellent separation efficiency and pH-stability.

Merck proved its HPLC technology leadership by introducing Chromolith®, monolithic silica columns for ultra fast separations at high efficiencies in analytical and semi-preparative dimensions. Chromolith® 4.6 mm i.d. columns easily can be used at 10 ml /min, thus increasing the throughput of an HPLC laboratory significantly. The new Chromolith® 3mm i.d. column is a new product for ultra fast LC-MS analysis.

LiChrospher® Bulk Packing Material

Merck KGaA, Darmstadt, Germany

Spherical silica carrier for constant results on high level: LiChrospher® are reliable and versatile traditionally produced spherical silica carrier. LiChrospher® silica carrier are available with different modifications. For the LiChrospher® RP-phases a selectivity and performance guarantee makes sure that these parameters remain constant form batch to batch and from year to year. The polar modified phases LiChrospher® CN, LiChrospher® NH2 and LiChrospher® DIOL as well as LiChrospher® Si with no modification are best for normal phase HPLC. Furthermore LiChrospher® PAH is highly efficient and selective for the separation of PAH.

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. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
