    • Solid phase extraction (SPE) disks provide the greatest extraction efficiency when the maximum surface area of the disk is exposed to the sample. Such may be accomplished with the present disclosure wherein an SPE disk is secured within a cavity of a disk holder apparatus such that the SPE disk compresses against a side wall defining the cavity and forms a seal therebetween. The disk holder apparatus may be used in an open design for vacuum applications, or in a sealed design with a closure, when using positive pressure to force the sample through the disk. Examples of various configurations for the disk holder apparatus and methods of use are provided.
    • 当磁盘的最大表面积暴露于样品时,固相萃取(SPE)磁盘提供最大的提取效率。 这可以通过本公开实现,其中SPE盘固定在盘保持器装置的空腔内,使得SPE盘压靠限定腔的侧壁并在其间形成密封。 当使用正压迫使样品通过盘时,盘保持器装置可以以开放设计用于真空应用,或者以具有封闭件的密封设计使用。 提供了用于盘保持器装置和使用方法的各种配置的示例。
