Abstract
A membrane comprising graphitized carbon black (GCB) with dual function for solid-phase extraction and surface-assisted laser desorption mass spectrometry (SPE/SALDI-MS) analysis is disclosed. Devices extraction comprising such membrane and methods utilizing such membranes are also disclosed.
Claims16
A particle loaded membrane, which is porous such that a liquid may pass through it comprising a support and particles attached to the support, for solid-phase extraction of an analyte from a sample to be analysed, characterized by that:
- i) the particles comprise graphitized carbon black (GCB) or derivates thereof;
- and
- ii) the support is suitable for surface-assisted laser desorption ionisation mass spectrometry (SALDI-MS) of analytes extracted on the particles.
