    摘要： A liquid chromatography configuration providing at least three dimensions of separation coupled with spectrometry greatly improves the ability to detect ions present in samples, including complex biological samples such as blood. Liquid chromatography columns in one embodiment are connected with an in-line trapping column the alternately communicates with the second and third liquid chromatography columns. The liquid chromatography columns are operably connected either to a mass spectrometer (MS) or a nuclear magnetic resonance (NMR) spectrometer. The improved dynamic range of detection allows a method of detecting molecular components present in complex biological samples that serve as biomarkers for a disease state, such as sepsis.

    摘要： A substrate for use in providing an ionized target comprising a structured substrate has a plurality of recesses, at least a portion of the plurality of recesses containing an initiator, the substrate being capable of having a target loaded on it. In one methods, irradiation of the substrate can cause the initiator to restructure, releasing it from the recesses and thereby desorbing and ionizing the target. The target so desorbed and ionized can be detected by mass analyzers. The mass of the targets at a given point on the surface can be recorded to provide a spatial mapping of the targets on the surface.
