Characterization of Nutrients and Actives in Herbal Supplements and Nutriceuticals Using UHPLC-Multi-Reflecting Time-of-Flight Mass Spectrometry
Poster Jun 14, 2011
Jeffrey S. Patrick, Kevin Siek and Joe Binkley
In this poster, extracts and various supplement dosage forms are introduced via direct infusion or UHPLC separation and analyzed by mass spectrometry (MS). Ultra-high resolution MS was performed using a multi-reflecting time-of-flight MS (MR-TOFMS). The analyses provided chemical fingerprints which are qualitatively and quantitatively distinct. The utility of these resolving powers and acquisition speeds for facile determination of elemental composition and resultant unknown identification is demonstrated. The utility of in-source CID (isCID) to provide supplemental structural information is also presented.
Application of Solid Phase Micro Extraction (SPME) and On‐Fiber Derivatization to Detect Precursors of Biomolecules in the study of Proto‐metabolismPoster
In the studies of origins of life, plausible synthetic reaction pathways to form biological relevant molecules, or building blocks of proto‐bilayer lipids, protein, RNA, and DNA in the primitive environment have been investigated intensively.READ MORE
A New Tool for the Automated Sample Preparation of Whole Blood Samples by LC-MS using a Commercial AutosamplerPoster
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.
