Chromatography Columns

Supplier: Merck

This intermediate polarity column is mainly designed for analyses of volatile organic compounds (VOCs), offers great retention and resolution of highly volatile compounds.

Supplier: Merck

BIOshell™ 160 Å Peptide CN columns provide an alternative selectivity to the traditional C18 bonded phases.

Supplier: Merck

These columns with excellent retention and resolution of polar compounds are less hydrophobic than C18 columns.

Ascentis® Express AQ-C18 are high-speed, high-performance liquid chromatography columns, based on the Fused-Core® particle design.

Supplier: Merck

This column with bonded poly(ethylene glycol) phase allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components.

Dual layer SPE tube that contains Na2SO4 (upper layer) and Florisil (magnesium silicate; lower layer) separated and packed with PTFE frits (glass tubes) or PE frits (PP tubes).

Supplier: Merck

Ascentis® Express PAH is a non endcapped C18 bonded phase with a proprietary manufacturing process designed on proven Fused-Core® technology to provide a fast and efficient separation of PAH compounds.

Supplier: Merck

ZIC®-pHILIC has the same stationary phase as ZIC®-HILIC, but is instead based on a polymeric particle for enhanced pH stability. The lack of silica practically nullifies background in high sensitivity detectors such as charged aerosol used for determination of organic and inorganic ions.

EXtrelut® NT is a specially processed, inert, wide pore kieselguhr with a high pore volume. It has been used for quite some time within research, for the sample preparation of urine, whole blood, plasma and other biological matrices. Other applications include environmental and residue testing such as analysis of industrial, domestic and wastewater. EXtrelut® NT is supplied either pre-packed in cartridges or as a loose sorbent. EXtrelut® NT simplifies liquid-liquid extraction by replacing separation funnels. Using a single step is more efficient, saves solvent, as well as material and time, in contrast to classic funnel separation. The aqueous sample is simply applied to the EXtrelut® NT sorbent. It distributes itself over the chemically-inert matrix so acting as a stationary phase. Subsequently, elution takes place using organic solvents that are non miscible with water. All the lipophilic substances are extracted from the aqueous into the organic phase.

Silica based SUPELCOSIL™ LC-NH₂ columns separate monosaccharides, disaccharides, and some trisaccharides, with elution generally in order of increasing molecular weight. Retention decreases as the proportion of water:acetonitrile in the mobile phase is increased.

Supplier: Merck

This Reversed phase Supelclean™ ENVI-18 are suitable for excellent for cleaning, extracting and concentrating pollutants from aqueous environmental sample (drinking, ground, waste water). Also suitable for extracting herbicides, fungicides and pesticides from waste material.
