    • A method and a system for generating an extraction sample from a dried sample spot. The method includes acquiring a spectroscopic image of an analyte in the spot. The spectroscopic image includes information on a spatial distribution of the analyte. A region of the spot to be extracted is determined from the spectroscopic image and an extraction sample is generated from the determined region. In other embodiments, the method and system are based on acquiring a spectroscopic measurement of an analyte in the dried sample spot, determining a quantity of the analyte in the spot based on the spectroscopic measurement and determining a volume of an extraction solvent for creating an extraction sample from the spot. The determined volume is based on the determined quantity of the analyte and a detection characteristic of an analytical measurement system. In other embodiments, the method is applied to solid samples.
    • 一种用于从干燥的样品斑点产生提取样品的方法和系统。 该方法包括获取斑点中分析物的分光图像。 分光图像包括关于分析物的空间分布的信息。 从分光图像确定要提取的光斑的区域,并且从确定的区域产生提取样品。 在其他实施方案中,该方法和系统基于获取干燥样品斑点中的分析物的光谱测量,基于光谱测量确定斑点中的分析物的量并确定用于产生提取的提取溶剂的体积 从现场抽样。 所确定的体积基于所确定的分析物的量和分析测量系统的检测特性。 在其他实施方案中,将该方法应用于固体样品。
