Big Pain Assays Aren't a Big Pain with the Raptor Biphenyl LC Column

Featured Application: 231 pain management and drugs of abuse compounds in under 10 minutes by LC-MS/MS

  • 231 compounds, 40+ isobars, 10 drug classes, 22 ESI- compounds in 10 minutes with 1 column.
  • A Raptor SPP LC column with time-tested Restek Biphenyl selectivity is the most versatile, multiclass-capable LC column available.
  • Achieve excellent separation of critical isobars with no tailing peaks.
  • Run fast and reliable high-throughput LC-MS/MS analyses with increased sensitivity using simple mobile phases.

The use of pain management drugs is steadily increasing. As a result, hospital and reference labs are seeing an increase in patient samples that must be screened for a wide variety of pain management drugs to prevent drug abuse and to ensure patient safety and adherence to their medication regimen. Therapeutic drug monitoring can be challenging due to the low cutoff levels, potential matrix interferences, and isobaric drug compounds. To address these challenges, many drug testing facilities are turning to liquid chromatography coupled with mass spectrometry (LC-MS/MS) for its increased speed, sensitivity, and specificity.

As shown in the analysis below, Restek's Raptor Biphenyl column is ideal for developing successful LC-MS/MS pain medication screening methodologies. With its exceptionally high retention and unique selectivity, 231 multiclass drug compounds and metabolites—including over 40 isobars—can be analyzed in just 10 minutes. In addition, separate panels have been optimized on the Raptor Biphenyl column specifically for opioidsantianxiety drugsbarbituratesNSAIDs and analgesicsantidepressantsantiepilepticsantipsychoticshallucinogens, and stimulants for use during confirmation and quantitative analyses.
