Disclosed is a fraction collector for dispensing liquids into plural receptacles (P1,P2) arranged in a two dimensional array. The fraction collector comprises a table (22) for supporting said receptacles, and an arm supported above the table, in tum supporting a liquid dispenser (35), the fraction collector arm is rotatable about an arm axis (C) and the liquid dispenser is movable along the arm on a carriage 34 (FIG. 2). Thereby, the dispenser is low cost and is repositionable simply above the receptacles as a result of said rotation and as a result of said movement along the arm, without occupying too much laboratory bench space.

An apparatus for collecting liquid fractions from a separation/reaction apparatus (1). A capillary (2) guides an extracted liquid fraction to a branching unit (3), a collection arrangement (4) carries a plurality of target vessels (5) receiving the liquid fraction from the capillary and a fluid line (6) is flow-connected to a fluid pump (7) and opens into the branching unit. The capillary and the fluid line each have outlet openings in the direct vicinity of one another at their end facing a target vessel such that liquid emerging from the outlet opening (2′) of the capillary transitions into the outlet opening (6′) of the fluid line. This precludes back mixing with earlier/later liquid fractions, precludes uncontrolled dripping of sample substance at the transfer point, speeds displacement of the target vessels in the collection arrangement, facilitates automation of the fraction processing procedure, and results in a more compact fraction collection apparatus.

A fluidic system for fraction collection comprises a switching valve having a plurality of ports for connecting first and second ports in different configurations. An inlet line is directly connected to the first port, and a collection device is directly connected to the second port. In a collection configuration, the first port and the second port are connected. The ports further comprise third and fourth ports, and the fluidic system further comprises a buffer section directly connected to the third and fourth ports. The fluidic system further comprises a first collection reservoir and is configured to position the collection device to expel a fluid into the first collection reservoir. In a buffer configuration, fluid flows through the inlet line, the first port, the third port, the buffer section, the fourth port, the second port, and the collection device.

A wearable health monitoring device includes a band configured to attach the wearable health monitoring device to a user's body; a VOC detection device configured to collect and analyze volatile organic compounds given off from the user's skin to identify specific health-indicative volatile organic compounds indicative of a health condition; and a biomarker sensor configured to detect a biomarker of the user.

Described is a dispensing needle for a fraction collector. The dispensing needle includes a conduit having a fluid channel to conduct a chromatographic flow, an interior wall that defines the fluid channel, an exterior surface and an endface through which the chromatographic flow is dispensed. The dispensing needle also includes a coating of a hydrocarbon material or a fluorocarbon material that is bonded to the endface. The coating is also bonded to at least a portion of the exterior surface that is adjacent to the endface and at least a portion of the interior wall that is adjacent to the endface. The coating operates to reduce a droplet volume of a liquid dispensed from the endface that may remain at the tip of the dispensing needle. Consequently, the concentration variation in a collected fraction due to a missing droplet or extra droplet is reduced.
