Rapid Perfluorinated Alkyl Acid Analysis by LC–MS/MS Increases Sample Throughput

July 01, 2017

• 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.

Accurate Pain Management Analysis in Under 5 Min on Raptor Biphenyl Superficially Porous Particle LC Columns

October 01, 2016

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.
