You Searched For: Chromatography Columns

Chromatography columns separate molecules within mixtures during gas or liquid chromatography. Filled with stationary phase compositions or chemical compounds, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual solvent polarity, composition, and size. The right chromatography control system allows to automate the delivery of cleaning, sanitizing and conditioning buffers to the packed column, and can enable to cycle the chromatography column several times during the batch, requiring smaller columns and subsequent lower capital investment.

Description: <B>Purospher® RP-18</B> is designed for the separation of problematic basic compounds with simple neutral eluents. In addition Purospher® RP-18 allows the separation of hydrophilic compounds with aqueous mobile phase. Purospher® RP-18 is based upon a high purity, metal-free silica. The multi-step chemical modification and deactivation of the surface, and the polar endcapping, enables a peak-tailing-free elution of basic and chelating compounds. Purospher® RP-18 is not suitable for the separation of acidic compounds. The good chemical stability of Purospher® RP-18 enables the use of mobile phase conditions at pH 8 for a long period of time.

Description: LiChrolut® solid phase extraction (SPE) cartridges and accessories are manufactured to the highest standards. All SPE cartridges listed below are polypropylene unless otherwise stated. They are compatible with all automated SPE instruments and robots. Three important criteria are carefully controlled.
Supplier: Merck
Description: ZIC®-cHILIC is based on the same technology platform as ZIC®-HILIC, but has a different functional group and an improved manufacturing procedure. The different charge orientation of the zwitterionic functional group leads to a different – and complementary – selectivity for polar hydrophilic compounds. This selectivity is especially beneficial for hydrophilic compounds that are negatively charged, positively charged, zwitterionic or neutral, for example, organic acids, amino acids, metabolites, aminoglycosides and nucleotides.

Description: Cyano columns are generally more polar than traditional alkyl silica columns. The functional groups are highly ordered, reducing steric hindrance for the solute. The modification also allows cation exchange activity, which is higher at neutral pH than in acidic conditions. Chromolith® CN columns are suitable for the separation of alkaloids, oils, flavonoids, glycols, phenols, phthalates, steroids and sulfonamides.
