Rapid Perfluorinated Alkyl Acid Analysis by LC–MS/MS Increases Sample Throughput
October 01, 2017
By switching to a Raptor C18 column, labs can process more samples per hour while still meeting fluorochemical method requirements.
Rapid Perfluorinated Alkyl Acid Analysis by LC–MS/MS Increases Sample Throughput

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.
Rapid and Accurate LC–MS-MS Analysis of Nicotine and Related Compounds in Urine Using Raptor Biphenyl LC Columns and MS-Friendly Mobile Phases
July 01, 2015
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.
