A holder rack has an array of tubular slots that cooperate with a holder to position an absorbent tip of the holder at a predetermined location. The racks fit over well plates to position each absorbent tip adjacent the bottom of a different well in the well plate to extract dried samples from the absorbent tips. The holders are transported in containers having a frame to receive the holders and a lid to keep them in the container. The absorbent tips can extend through a cap to dry, with the cap connected to the holder to enclose the absorbent tips for transport.

Method and apparatus for handling blood for testing

A slurry chamber is fastened to and held in coaxial alignment with a chromatography column by a V-band. One end of the column has an end cap and frit. A slurry of fluid and chromatographic media is placed in the column and chamber. A piston is forced through the chamber and into the column by a hydraulic ram to expel the fluid and form a media bed in the column. The slurry chamber is removed, and a split end cap is fastened to the column. A threaded recess in the split end cap receives a split, threaded collet. The collet is tightened until it pushes against the piston with the same force as the ram, at which point the ram is released and the column removed for use.

HPLC column

A blood sampling device is provided having holder with a manipulating end and an absorbent probe on the opposing end. The probe is of hydrophilic polymer sized to directly absorb a predetermined volume of up to about 30 microliters of blood. Ribs on the holder position the probe within a compartment of a container to prevent contact with the container. The ribs also position the probe within extraction wells.

Method and apparatus for acquiring blood for testing

An advanced silica gel sorbent for use in chromatographic separations that has been chemically modified by surface polycondensation of a trifunctional and/or difunctional organosilane. The chromatographic media exhibits a wider pH range and improved pH stability as compared to other silica gel based sorbents, while retaining all other positive aspects attributed to silica gel based sorbents. A method of forming the advanced silica gel sorbent by Templated Multilayer Inorganic/Organic Grafting.
