| 20100133806 | FERRULE FOR MAKING FINGERTIGHT COLUMN CONNECTIONS IN GAS CHROMATOGRAPHY - A ferrule arrangement for use in sealing connections to gas chromatography columns includes a generally tubular metal ferrule with an axial bore to receive a fracturable column with a protective coating. The ferrule has a forward part that tapers to a tip region of the ferrule. A generally tubular former has a socket portion to receive the ferrule and further has an internal conical surface that, after such receipt, engages the forward part of the ferrule. A portion is provided on either or both of said ferrule and the former by which the ferrule and former may be directly or indirectly relatively moved together by application of finger force. The taper and the internal conical surface exhibit relative taper angles and the tip region of the ferrule is sufficiently radially thin whereby the application of finger force (i) is adequate to move the ferrule axially into the former to cause the conical surface to engage the tip region of the ferrule and to deform the tip region into sealing engagement with the protective coating of the column, but (ii) does not break the column. | 06-03-2010 |
| 20090218412 | NON-CONTACT DISPENSING OF LIQUID DROPLETS - Apparatus and method for dispensing droplets of a liquid includes structure providing a passage along which the liquid may be delivered to form a droplet at an orifice. The structure is configured to propagate a shockwave to impact the droplet and thereby to displace it from the orifice, whereby the droplet is dispensed. The structure may provide an elongate passage to longitudinally receive a syringe needle positionable with its tip, and the orifice at the tip, at or adjacent on open end of the passage, one or more needle guides to locate the needle in the passage, which is of greater cross-section than the needle at the open end, and a seal arrangement to substantially seal the passage about the needle at a position displaced from the open end of the passage whereby to define a chamber between the position and the open end. A syringe drive device may have a head adapted to be coupled to a syringe and means to operate the syringe to dispense droplets by free-fall from the syringe tip orifice, and structure adapted to be selectively coupled to the head and/or to a syringe carried thereby. | 09-03-2009 |
