SB-800 HQ are polyhydroxymethacrylate-based SEC columns for the molecular weight distribution analysis of water-soluble polymers. The solvent can be substituted with DMF (except for SB-802 HQ and SB-807 HQ columns), enabling the analysis of polar polymers.

Supplier: Agilent

These columns are not bonded or cross-linked, and are therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Because SE series columns are not bonded or cross-linked, solvent rinsing is not recommend.

Supplier: Restek

Chromegasphere SI60 Silica HPLC columns are made up of metal free ultra-high purity synthetic silica. TLC solvent systems translate directly to the Chromegasphere SI60 HPLC columns and the high loading capacities permit preparative scale separations.

Supplier: Agilent

General purpose columns for solvents, sulfur compounds, oxygenated compounds, C1 to C3 isomers, methane, air/CO, and alkanes upto C12. Ideal for ethane, ethylene and ethyne separation.

Supplier: PerkinElmer

SPE Supra-Clean® high recovery REC18 are silica based columns with 15% of carbon load. Ideal for extracting non-polar and mid-polar compounds including 100% water solvents when analysing drugs and drug metabolites in biological matrices, trace organic material in water, toxins in food.

Supplier: Restek

These cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).

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: Restek

Frit adaptors

Supplier: SCIENCIX

Replacement parts for OEMs such as Agilent, Shimadzu and Waters chromotograpy systems. Equivalent to the corresponding OEM part.

Supplier: Restek

General purpose columns for arson accelerants, essential oils, hydrocarbons, pesticides, PCB congeners (e.g. Aroclor mixes), sulfur compounds, amines, solvent impurities, simulated distillation, oxygenates, gasoline range organics (GRO), refinery gases.

Supplier: Thermo Fisher Scientific

Flat, 100% porous graphitic carbon (PGC) with selectivity for structurally similar compounds, offering separation of compounds with simple solvents. Hydrophobic reversed phase; normal phase adsorption; polar retention.

Supplier: Restek

Stabilwax-MS columns ensure reproducible retention times from run to run, even with temperature cycling. When methods require trace analysis, this highly polar, low-bleed stationary phase produces excellent signal-to-noise levels. Ideal for food and flavor analysis (e.g., essential oils), fragrance and allergen analysis, as well as industrial solvent and chemical analysis.

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.

Supplier: Agilent

Kit includes all capillaries and fittings, as well as bulk PEEK capillaries and a capillary cutter to add maximum flexibility.

Supplier: VARIAN

Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Supplier: Agilent

These columns allow chromatographers to employ essentially any organic solvent as mobile phase to develop methods for the most challenging separations. These columns are available in a variety of particle sizes and offer great speed and column resolving power. Columns packed with 3 µm CSPs offer high speed separations and a reduction in analysis time and cost per sample. Columns, packed with 3 µm particles, may be used in conventional HPLC units without significant loss in performance, even with the smaller column dimensions.
