A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

Supplier: VARIAN

CP-PoraPLOT U and CP-PoraPLOT S provide symmetrical peaks from polar and non-polar volatiles for ultimate accuracy.

Supplier: VARIAN

The Dynamax preparative column hardware utilizes a patented dynamic axial compression (DAC) design and is the ideal format for the development and optimization of a high throughput or high yield purification.

Supplier: VARIAN

Bond Elut CN-U is ideally suited for the extraction of polar compounds from a nonpolar matrix, such as hexane or oils. It is suitable for very polar analytes that may be irreversibly retained on SI or Diol (2OH) SPE phases.

Supplier: VARIAN

Hexafluoroisopropanol (HFIP) is used as a solvent in GPC for the analysis of important industrial polymers such as polyesters, polyamides and polylactide/glycolide copolymers. For greatly improved performance in extremely polar solvents such as HFIP and trifluoroethanol, we have developed novel 'multipore' technology to produce PL HFIPgel, a PS/DVB packing featuring a monodisperse particle size, high pore volume and high resolution.

Guaranteed analysis of FAME cis/trans isomers for complete confidence.

Supplier: Merck

These columns are situated between the traditional non bonded cyanosilicone phases SP-2330 and SP-2340 in polarity. The high polarity of this phase allows the separation of geometric (cis/trans) fatty acid methyl ester isomers as a group.

Supplier: Agilent

Polyethylene glycol column

Supplier: Agilent

Eliminates particle leakage to improve data quality with light scattering detection. Typical applications: polyethylenes, polyolefins. Compatible with organic solvents.

Supplier: Agilent

These columns are ideal for confirmational analyses. They have very low bleed characteristics, ideal for GC/MS.

Supplier: Merck

Specially prepared and tested columns to seperate geometrical position (cis/trans) isomers of fatty acid methyl esters. Seperation of FAMEs should be take place in hydrogenated vegetable oil samples.

Supplier: VARIAN

Bond Elut™ Mycotoxin is a novel sorbent which cleans up food extracts for improved trichothecene and zearalenone analysis. Results are comparable or superior to competing methods, including immunoaffinity columns (IaC) and charcoal/alumina columns. The sorbent is a proprietary silica-based ion exchange material.

Supplier: VARIAN

MonoChrom® columns provide excellent chromatography of organic amines, organic acids, amphoteric compounds and neutral compounds.

Supplier: VARIAN

Ideal as primary or confirmation column.

Supplier: VICI JOUR RESEARCH

The in-line PEEK guard cartridges extend the life of analytical columns by trapping contaminants from the sample and mobile phase, thereby preventing loss of retention. Only PEEK and titanium contacts the mobile phase and sample. This system is ideal for use with proteins or other biopolymers that may be contaminated or absorbed by steel surfaces.

Supplier: SciLabware

These chromatography columns are made from PYREX®, borosilicate glass.
