A PROBE FOR EXTRACTION OF MOLECULES OF INTEREST FROM A SAMPLE |
摘要 |
The present disclosure describes a device for generating ionized molecules for analysis in a mass spectrometer. The device includes: a mesh substrate coated with an extraction phase, the extraction phase comprising a polymer that absorbs a molecule of interest from a matrix, or a polymer and solid phase microextraction (SPME) particles having pores dimensioned to absorb a molecule of interest from a matrix, where the mesh substrate has a sufficiently open structure to allow fluid to flow through the mesh substrate; and a solid substrate connected to the mesh substrate to provide stability to the coated mesh substrate. Mass spectrometry systems that include such a device are also described. Methods of analyzing an analyte previously extracted from a matrix onto the device are also described. |
