    Sigma-Aldrich

    eCl@ss 32110501 General Description SUPELCOSIL LC-PAH columns were designed specifically for analyses of the priority pollutant PAHs listed in US EPA Method 610. 2.1 mm and 3.0 mm columns save solvent and improve sensitivity when sample mass is limited. 3 μm columns provide extremely rapid,...

  • Placeholder Image for Hp Blood Alcohol Analysis Column

    Agilent Technologies

    Reliable blood alcohol analysis Excellent confirmation column with DB-ALC2 for method using t-butanol as internal standard

  • Thumbnail Image for Bulk Phenyl 2

    Separation Methods Technologies

    SMT Phenyl bulk packings provides unique selectivity for aromatic compounds when compared to other reversed-phase packings such as C18 and C8. The ìÛ-electrons of the phenyl group can interact with the aromatic ring of an analyte to increase retention relative to less or non-aromatic...

  • Thumbnail Image for Metrosep A Supp 7 - 250/4.0 Column

    Metrohm

    Disinfection byproducts from water treatment are suspected not only of being health hazards but also of being carcinogenic. Oxyhalides have therefore become the subject of many investigations and standards (e.g., EPA 300.1 Part B, EPA 317.0, EPA 326.0). Of primary concern is bromate, which forms...

  • Thumbnail Image for Ascentis® ES-Cyano HPLC Column 5 µm particle size, L × I.D. 15 cm × 4.6 mm

    Sigma-Aldrich

    Features and Benefits Enhanced stability at low pH Operates in reversed-phase, HILIC, and normal phase modes of chromatography Low MS bleed 100% aqueous compatible Available as 3 μm and 5 μm particles Particle composition: Type B silica gel Particle shape: Spherical Extra stable for low pH...

  • Thumbnail Image for ProteCol® C18 G Reverse Phase HPLC Columns

    SGE

    Turn imagination into results with the ProteCol™ range of HPLC columns. With Reverse Phase, Normal Phase and Specialty Phases, ProteCol ensures you have the right phase for your separation needs. With the option of combining inert PEEK coated hardware or traditional stainless steel with each...

  • Thumbnail Image for Resprep® EPH Fractionation SPE Cartridges

    Restek

    These cartridges have been specifically designed to provide consistent and reproducible results for the clean-up and fractionation of hexane-extractable petroleum hydrocarbons from soil and waste samples. Specially treated to reduce contaminants and increase capacity. Silica packing.

  • Thumbnail Image for Specialty CIB-Ovomucoid Columns

    Separation Methods Technologies

    SMT manufactures the first series of commercially available silica based CIB-Ovomucoid columns for high performance chiral separation of acid, base and neutral molecules. This total coverage technology ensures complete elimination of non-specific binding sites on the silica surface. The rigidity of...

  • Thumbnail Image for Bulk WAX

    Separation Methods Technologies

    SMT-WAX Bulk Packings are silica-based Weak Anion eXchange packing materials developed for separation of anionic compounds. SMT WAX Bulk Packings consist of chemically attached hydrophilic surface derivatized to form polyethyleneimine functionality. The technique of SAM is used in the bonding...

  • Thumbnail Image for Specialty CIB-ProteinA Columns

    Separation Methods Technologies

    SMT CIB-ProteinA are silica-based packing materials de- signed for both high performance and low-pressure purification of antibodies, IgG. In production of the ProteinA affinity-type columns, SMT utilizes its proprietary technique of self-assembled monolayer (SAM) of bonding to first immobilize...

  • Thumbnail Image for Specialty Chiral 2 Columns

    Separation Methods Technologies

    Chiral compounds, or enantiomers have identical molecular structures that are related as mirror images of one another much like a left hand is related to a right hand. Rapid and accurate stereochemical resolution of enantiomeric molecules has become a challenge in various aspects of pharmaceuticals...

  • Thumbnail Image for Normal Phase Diol 2 Columns

    Separation Methods Technologies

    SMT-Diol columns are developed as an alternative for silica columns used in normal phase separation methods. The Diol [-OH] functional group is controlled, and as such, provides more reproducible separation when compared to separation on silanols [-OH] from bare silica surface. Furthermore, the...

  • Thumbnail Image for Reversed-Phase C6 Columns

    Separation Methods Technologies

    SMT SAM-C6 columns consist of Hexyl as the functional ligand. The columns offer selectivities that are different from C8 and C18 reversed-phase columns when applied to separation of polyaromatic hydrocarbons. SMT-C6 columns are specially designed as complementary alternatives for the separation of:...

  • Thumbnail Image for Reversed-Phase MEB2 Columns

    Separation Methods Technologies

    SMT manufactures columns with short carbon chains for rapid analysis of basic, neutral, and mildly acidic drugs and small molecules. These columns provide excellent baseline resolution for small basic molecules including therapeutic drugs. The bonding scheme ensures proper deactivation substrate...

  • Thumbnail Image for Elite Series Reversed-Phase C18 Columns

    Separation Methods Technologies

    Elite-C18 Series: SMT SAM-C18 phases with the intermediate functional ligand coverage confirmed with carbon analysis results of 16% carbon load. In these series, the density of the functional ligand, octadecyl molecule or C18, is moderated with the proprietary spacer molecule to ensure maximum...
