Bond Elut™ plexa PAX non-polar/anion-exchange polymeric SPE offers excellent clean-up and reproducibility, and is suitable for polar and non-polar acidic analytes.

Supplier: VARIAN

Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

Bond Elut™ NEXUS is an ultra-clean polymeric sorbent which has bi-modal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no pre-conditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine.

Based on the same base polymer technology, Bond Elut™ NEXUS WCX is a weak cation exchange sorbent that offers extra selectivity for analytes, such as quaternary ammonium drugs and anabolic steroids.

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’.
