Solid phase extraction cartridges, Bond Elut™ PPL

Supplier: VARIAN

Bond Elut™ PPL is a styrene-divinylvenzene (SDVB) polymer that has been modified with a proprietary non-polar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution. Bond Elut™ PPL is suitable for EPA Method 528 ‘Determination of Phenols in Drinking Water by SPE and Capillary GC/MS’.

HPLC columns, Acclaim™ mixed-mode WAX-1

HPLC columns, Acclaim™ mixed-mode WAX-1

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.

HPLC columns, Hypersil™ CPS and CPS-2 cyano

Supplier: Thermo Fisher Scientific

Hypersil™ CPS (cyano) phases offer different selectivity than Hypersil™ Silica and APS-2. Cyano columns equilibrate rapidly and are not deactivated by small quantities of water. When used as a reversed phase material, cyano selectivity complements the alkyl chain bonded phases, but with lower hydrophobicity. Hypersil™ CPS-2 is the endcapped version.

Reversed phase HPLC columns, PRP-h5

Reversed phase HPLC columns, PRP-h5

Supplier: HAMILTON BONADUZ

PRP-h5 polimeric reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-h5 has no stationary phase coating. The integral reversed phase characteristics of the PRP-h5 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns. PRP-h5 columns are packed with a poly(styrene-divinylbenzene) material.
