Bond elut™ Cartridge Spe
Bond Elut NEXUS and Bond Elut NEXUS WCX: Pre-conditioned Free Polymeric SPE
• Large particle size allows excellent flow for viscous samples • Non-conditioning method saves time and improves throughput Typical Applications Horse urine, anabolic steroids, trace endocrine disrupters in water
• WCX offers enhanced selectivity for certain analytes such as quaternary amine drugs 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.
