By switching to a Raptor C18 column, labs can process more samples per hour while still meeting fluorochemical method requirements.

• Raptor C18 SPP 5 μm core-shell silica particle columns offer excellent resolution for fluorochemicals with short total cycle times. For even faster analysis, 2.7 μm core-shell particles are available. • Meets EPA Method 537 requirements. • Unique, robust Raptor C18 column design increases instrument uptime.

By switching to a Raptor C18 column, labs can process more samples per hour while still meeting fluorochemical method requirements.

Pain management LC analyses can be difficult to optimize due to the limited selectivity of C18 and phenyl-hexyl phases. In contrast, the selectivity of Raptor Biphenyl superficially porous particle (SPP) LC columns provides complete resolution of isobaric pain medications with a total cycle time of 5 min.

A rapid, accurate, and reproducible method was developed for high-throughput testing of nicotine, cotinine, trans-3’-hydroxycotinine, nornicotine, norcotinine, and anabasine in urine. Data show that a fast and highly efficient analysis of these basic compounds can be achieved with the Raptor Biphenyl column using standard reversed-phase LC–MS mobile phases that are compatible with a variety of LC–MS instrumentation.
