Descripción: 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.

Descripción: EXtrelut® NT es una tierra de diatomeas de poro ancho, inerte y especialmente procesada con un gran volumen de poros. Se utiliza desde hace tiempo en la investigación para la preparación de muestras de orina, sangre total, plasma y otras matrices biológicas. Otras aplicaciones incluyen pruebas ambientales y de residuos, como análisis de aguas industriales, domésticas y residuales. EXtrelut® NT se suministra preenvasado en cartuchos o como absorbente suelto. EXtrelut® NT simplifica la extracción líquido-líquido al reemplazar los embudos de separación. El uso de un solo paso es más eficiente, ahorra disolvente, así como material y tiempo, en comparación con la separación clásica con embudo. La muestra acuosa simplemente se aplica al absorbente EXtrelut® NT. Se distribuye por la matriz químicamente inerte, actuando así como una fase estacionaria. A continuación, se realiza la elución utilizando disolventes orgánicos que no son miscibles con agua. Todas las sustancias lipófilas se extraen de la fase acuosa a la fase orgánica.

Descripción: The Discovery® RP-Amide C16 HPLC Column with unique retention and selectivity.

Proveedor: Merck

Descripción: These bonded poly(5% diphenyl/95% dimethylsiloxane) low phenyl content columns improve thermal stability of the phase, while still providing essentially a boiling point elution order, and a slight increase in selectivity, especially for aromatic compounds.

Descripción: Ascentis® Express 90 Å Phenyl-Hexyl high-speed, high-performance liquid chromatography columns are based on a Fused-Core® particle design.

Proveedor: Merck

Descripción: 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.

Descripción: Ascentis® C8 HPLC columns are optimised to the three terms of the resolution equation: efficiency, retention, and selectivity.

Proveedor: Avantor

Descripción: Avantor® ACE® Oligo is a unique encapsulated stationary phase for high resolution ion-pair reversed-phase analysis of oligonucleotides. These high pH stable stainless steel columns are compatible with all buffers and mobile phases typically used for oligonucletide analysis by LC-UV and LC-MS, including TEAA and HFIP.

Descripción: Avantor® ACE® Excel® C18-Amide is a uniquely designed stationary phase offering improved retention of polar compounds, enhanced phenolic resolution and alternative selectivity to C18 bonded columns. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative.

Proveedor: Avantor

Descripción: Avantor® ACE® Excel® C18-PFP phase utilizes a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

Proveedor: Avantor

Descripción: The Avantor® ACE® Excel® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.
