Abstract
Emitters, compositions, and processes and methods for making emitters and compositions, useful for emitting sample for mass spectral analysis and/or acting as a stationary phase in chromatographic applications are described. Compositions according to the invention can comprise particles entrapped by polymer such that unoccluded channels are formed and the particles are substantially uncovered and able to interact with sample.
Claims37
An emitter comprising
- a plurality of particles collectively forming a plurality of channels, and
- a polymeric material adhesively disposed between at least a portion of adjacent said particles,
- wherein the channels are substantially unoccluded by the polymeric material.
Use of an emitter comprising
- a plurality of particles collectively forming a plurality of channels, and
- a polymeric material adhesively disposed between at least a portion of adjacent said particles,
- wherein the channels are substantially unoccluded by the polymeric material to provide a sample suitable for analysis by mass spectrometry.
