Abstract
In one aspect, a method of extracting a target analyte from a sample for introduction into a mass spectrometer is disclosed, which includes mixing the sample with a paramagnetic medium to form a mixture, subjecting the mixture to a magnetic field gradient to form a non-homogenous distribution of at least one of the analyte and at least one interfering component of the sample, if any, thereby enhancing a concentration of the target analyte within a spatial location of said mixture, extracting at least a portion of the target analyte from that spatial location, and introducing at least a portion of the extracted target analyte into said mass spectrometer.

A method of extracting a target analyte from a sample for introduction into a mass spectrometer, comprising:
- mixing the sample, which includes the target analyte and at least one interfering component, with a paramagnetic medium to form a mixture of the sample and the paramagnetic medium,
- subjecting the mixture to a magnetic field gradient to form a non-homogenous distribution of at least one of said target analyte and the at least one interfering component thereby enhancing a concentration of said target analyte within a spatial location of said mixture,
- extracting at least a portion of said target analyte from said spatial location, and
- introducing at least a portion of said extracted target analyte into said mass spectrometer.
