Abstract:
1. A system for extracting a sample analyte with a liquid, comprising: a sample collection device comprising a continuous portion of porous sample collection material, the porous sample collection material being capable of absorbing the sample such that the sample penetrates below the surface of the porous sample collection material; predetermined regions of the continuous porous sample collection material defining barrier regions for containing the flow of sample extraction liquid; a hydrophobic material coating the porous sample collection material in the barrier regions for containing the flow of sample extraction liquid, the hydrophobic material comprising patterns in the porous sample collection material forming sample wells prior to depositing the sample, the sample wells being non-reactive with the analyte; a liquid extraction surface sampling probe for applying the extraction liquid to the surface of the porous sample collection material, and for withdrawing extraction liquid containing extracted sample from the same surface of the porous sample collection material through the liquid extraction surface sampling probe; and further comprising ionizing the extracted dissolved sample material downstream of the porous material and the liquid extraction surface sampling probe.
