Bond Elut NEXUS is an ultra-clean polymeric sorbent, which has bimodal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no preconditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine. Bond Elut NEXUS WCX is a weak cation-exchange sorbent that offers extra selectivity for analytes such as quaternary ammonium drugs and anabolic steroids.
Large particle size allows excellent flow for viscous samples
Nonconditioning method saves time and improves throughput
WCX offers enhanced selectivity for certain analytes, such as quaternary amine drugs
