Abstract: A method for identifying a polypeptide a specimen can include (i) treating a specimen suspected of including an insulin with a base; (ii) extracting a first fraction of the treated specimen by solid phase extraction using a mixed mode or polymeric reversed-phase media and a first solvent including an acid; (iii) separating a component of the first fraction by liquid chromatography using a chromatographic surface including a hydrophobic surface group and one or more ionizable modifiers, and a second solvent including an acid; and (iv) analyzing the component of the first fraction by mass spectroscopy, thereby identifying the polypeptide, if present, using a signal corresponding to a sequence fragment ion from the polypeptide. The signal can correspond to an intact multiply charged precursor fragment selected in a first quadrupole and its corresponding sequence fragment ion selected in a final quadrupole.

Abstract: Described is a device for solid phase extraction of a dried sample of a biological fluid. The device includes a support structure such as a plate or support block that has a first side to receive a dried sample card. The support structure also has a second side that is opposite the first side and a number of apertures that extend between the first and second sides. The device also includes a plurality of wells each containing a sample preparation material and having an inlet end that communicates with a respective aperture at the second side of the support structure. Each dried sample on the dried sample card is aligned with one of the apertures. Extraction samples in each well pass through the sample preparation material, such as a chromatographic sorbent, in the well to remove one or more constituents of the extraction sample.

Abstract: The present disclosure relates to a method of analyzing a sample comprising a hydrophobic molecule. The method includes preparing an aqueous solution comprising the sample. The method also includes placing the solution in contact with a polypropylene substrate having a deactivated surface that reduces adsorption of the hydrophobic molecule relative to a polypropylene substrate that has not been deactivated. The method also includes analyzing the sample.
