摘要： The present invention provides a novel procedure of preparing samples for analysis by way of mass spectrometry, preferably LC-MS/MS. Accordingly, functionalized magnetic particles with a hydrophobic surface were used for extracting low molecular weight compounds from complex liquid biological samples such as plasma, serum, whole blood or hemolyzed blood. The method of the invention includes (a) contacting the sample with an amount of functionalized magnetic particles with a hydrophobic surface, (b) incubating the sample and the particles, thereby adsorbing the compound to the hydrophobic surface, (c) separating the particles by applying a magnetic field and removing the liquid, (d) optionally washing the particles, (e) eluting the compound from the particles.

摘要： The invention relates to a method for differentially hemolyzing whole blood. It discloses method for detecting an analyte in a liquid sample known or suspected to comprise red blood cells and suspected or known to comprise eukaryotic cells, the method comprising the steps of processing said liquid sample with a membrane solubilizing agent under conditions appropriate to lyse cell membranes of red blood cells and at the same time not to cause precipitation of sample constituents, subjecting the processed sample to a chromatographic separation, and detecting the analyte. The differential hemolysis of red blood cells is of advantage in a method of detecting an analyte in a liquid sample that may comprise both erythrocytes as well as nucleated cells. The differential solubilization of red blood cells can be easily combined with an online detection methodology, like LC-MS, and is advantageous in the detection of many analytes, e.g. in the detection of folate or of immunosuppressive drugs, like tacrolimus or sirolimus.
