Supplier: VARIAN

Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.

Supplier: VARIAN

Microsorb™ Silica is ideal for the separation of low molecular weight compounds that dissolve in organic solvents. Separations on silica columns depend upon the difference in orientation, type and number of functional groups associated with the compounds in the sample.

Supplier: MACHEREY-NAGEL

The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column. The retention gap depends on the solvent used:

Supplier: Restek

The reversing cartridge design allows convenient inverted elution of strongly retained analytes using minimum solvent volumes. Ideal for extraction of pesticides in water.

Supplier: Thermo Fisher Scientific

WebSeal™ 7 mm diameter Round 96-well plate Sealing mats are designed to ensure high quality data with an uninterrupted workflow for high-throughput applications using GC and HPLC/UHPLC and are ideal for regulated labs that use water and polar solvents.

Supplier: Resonac

These are styrene divinylbenzene copolymer-based organic solvent SEC (GPC) columns. Suitable for a wide range of applications from low to high molecular weight compounds.

Supplier: Restek

MXT®-200 columns are general purpose columns for solvents, Freon® fluorocarbons, alcohols, ketones, silanes, and glycols.

Supplier: Agilent

Recommended columns for alcohols, free organic acids, solvents, essential oils, flavors and fragrances.

Supplier: Agilent

Poroshell 120 is made with a superficially porous particle that has a solid silica core and a porous outer layer. This particle provides high efficiency at lower pressures and is ideal for fast or high-resolution separations of many types of analytes.

Supplier: Restek

Intermediate-polarity deactivated guard/retention gap columns are useful for a wide range of applications and are proven to be compatible with most common solvents.

Supplier: Resonac

Supplier: COLLECTION PREFIX HPLC

The Systec® Stand-Alone Prep-Scale HPLC vacuum degassing systems is high-efficiency, in-line modules that remove dissolved gases from the mobile phase. Their unique design assures reliable continuous operation and the highest level of performance available without the need for helium sparging. Up to five solvent lines may be degassed simultaneously by one unit.

Supplier: Thermo Fisher Scientific

These columns result in a multimode separation mechanism including hydrophobic, anion-exchange and cation-exclusion interactions. Consequently, retention of basic, neutral and acidic molecules can be either independently or concurrently adjusted by changing ionic strength, pH and organic solvent content in the mobile phase.

Supplier: Thermo Fisher Scientific

For ultrahigh-resolution UHPLC analysis of synthetic oligonucleotides. These strong anion-exchange columns resolve full-length oligonucleotides from n–1, n+1, and other failure sequences not possible with other columns. Control the retention times and selectivity by choice of salt, pH, and solvent, and tailor the separation to the requirements of your different oligonucleotide analysis challenges.
