April 14, 2010 Absorption Systems, a leader in testing drugs for ADMET (Absorption, Distribution, Metabolism, Excretion and Toxicity), announced today that the company has incorporated the Thermo Scientific LTQ Orbitrap XL Hybrid Fourier Transform mass spectrometer into its drug metabolism program. The introduction of the state-of-the-art technology enables more precise identification of drug metabolites and quantification of the most challenging low-level components in complex biological matrices. The LTQ Orbitrap XL, developed by Thermo Fisher Scientific, is based on the fast and sensitive LTQ XL™ linear ion trap mass spectrometer and the Orbitrap mass analyzer. This combination results in an instrument with unsurpassed capabilities for metabolite identification, while retaining sensitivity and dynamic range. The LTQ Orbitrap XL can perform quantification of a parent drug in complex biological matrices (from in vitro microsomal incubates to plasma samples generated in the course of an in vivo pharmacokinetic study), while automatically detecting plausible metabolites and acquiring MS(n) data required for their structural elucidation. Metabolite ID is an important element of Absorption Systems’ drug metabolism program. It is required by regulatory agencies, helps researchers select the most appropriate nonclinical tox species based on exposure to all major human metabolites and predicts unique or disproportionate human metabolites. In addition, metabolite ID highlights metabolic “soft spots” and certain structural features that may predict toxicity of metabolites. “Absorption Systems consistently utilizes the most advanced, proven technologies available to support customers’ drug metabolism and other ADMET programs,” commented Patrick M. Dentinger, President and CEO of Absorption Systems. “The LTQ Orbitrap XL provides our clients with superior precision, sensitivity and performance when conducting metabolite ID.” For more information on Absorption Systems, visit
