New EtG/EtS Column Solves Matrix Interference Problems

Sep 15 2017 Comments 0

A Raptor EtG/EtS column is your solution. Typical methods for EtG and EtS analysis have several limitations: poor resolution from matrix components, long run times that limit sample throughput, and short column lifetimes. Restek has developed a new Raptor EtG/EtS column that consistently retains and resolves EtG and EtS from matrix interferences, providing accurate, reliable results injection after injection. Reliable performance and long column lifetime make this column ideal for alcohol consumption monitoring by high-throughput labs. Paired with Restek reference standards and its fast, 4-minute, dilute-and-shoot LC-MS/MS method, the Raptor EtG/EtS column allows you to analyse EtG/EtS samples with confidence.

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or ‘core-shell’ particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation.
