  • Compositions and methods for solid phase extraction of lipids
    Patent number: 10434492
    Abstract: A composition, method and device for the preparation of biological samples for subsequent instrumental analyses, such as GC, GC-MS, LC and LC-MS analysis, using a solid phase extraction (SPE) process is described. Through SPE process alone or an integrated combination of protein precipitation, filtration, and SPE using a hydrophobic zirconia-coated chromatographic media, interfering compounds, such as proteins, glycerides and phosphate-containing compounds, are eliminated from the biological, food, environmental and biotechnology samples, affording an enhanced analyte response during the instrumental analysis.
    Type: Grant
    Filed: May 21, 2010
    Date of Patent: October 8, 2019
    Assignee: Sigma-Aldrich Co. LLC
    Inventors: Xiaoning Lu, Olga I. Shimelis, Maochun M. Ye
