Abstract
A particle-packed membrane inlet (PPMI) for in situ separation of an analyte from a bulk sample matrix is disclosed. The PPMI includes a membrane configured to separate the analyte from the bulk sample matrix, a membrane capillary within the membrane, and a plurality of particles packed within the membrane capillary. The plurality of particles is configured to support the membrane capillary against collapse when the bulk sample matrix has a high pressure.
Claims21
A particle-packed membrane inlet (PPMI) for in situ separation of an analyte from a bulk sample matrix, the PPMI comprising:
- a membrane configured to separate the analyte from the bulk sample matrix;
- a membrane capillary within the membrane;
- and
- a plurality of particles packed within the membrane capillary, wherein the plurality of particles are configured to support the membrane capillary against collapse when the bulk sample matrix has a high pressure.
A method for in situ separation of an analyte from a bulk sample matrix, the method comprising:
- passing the bulk sample matrix along an outer surface of a membrane having a membrane capillary with the membrane, wherein
- the membrane capillary includes a plurality of particles packed within the membrane capillary, and
- the plurality of particles are configured to support the membrane capillary against collapse when the bulk sample matrix has a high pressure;
- separating the analyte from the bulk sample matrix by diffusing the analyte through the membrane into the membrane capillary;
- and
- transporting the analyte from the membrane capillary through the packed plurality of particles.
A particle-packed membrane inlet (PPMI) for in situ separation of an analyte from a bulk sample matrix, the PPMI comprising:
- means for separating the analyte from the bulk sample matrix;
- a lumen within the means for separating;
- and
- a plurality of particles packed within the lumen, wherein the plurality of particles are configured to support the lumen against collapse when the bulk sample matrix has a high pressure.
