POROUS MEMBRANE ENABLED MASS SPECTROMETRY CHARACTERIZATION OF MICROFLUIDIC DEVICES
A system for sampling a liquid includes a sample fluid conduit including a membrane having pores. The membrane prevents the passage of the sample liquid through the pores at a first pressure of the sample liquid in the sample fluid conduit. A surface sampling capture probe has a distal end. The capture probe includes a solvent supply conduit and a solvent exhaust conduit. A solvent composition flowing at the distal end of the capture probe establishes a liquid junction with the membrane and establishes a second pressure within the liquid junction at the membrane. The second pressure is lower than the first pressure. Sample liquid will be drawn through the pores of the membrane by the second pressure at the liquid junction. A method for sampling a liquid and for performing chemical analysis on a liquid are also disclosed.

PERSONAL SAMPLING FOR CLEAN ROOM APPLICATIONS
An interactive living entity automatic sampling system includes a structure supporting components including a first sensor, a second sensor, a robotic arm, a camera, and a touchless interface, wherein the structure and the components are adapted for use in a clean room. The first sensor is adapted to sense the interactive living entity in response to the interactive living entity being at a predetermined position relative to the structure for a predetermined time. The second sensor is adapted to sense an indicia associated with the interactive living entity. In response to the second sensor sensing the indicia, the sampling system initiates an operating cycle, or continues the previously initiated operating cycle, for collecting a sample from the interactive living entity. During the operating cycle, the touchless interface provides positioning instructions to the interactive living entity in combination with the robotic arm handling a partially enclosed container for collecting the sample from the interactive living entity.
