ABSTRACT:
A capillary fluid injector, particularly an automated capillary fluid injector, for dispensing very small accurately measured quantities of a fluid into a medium. A capillary opening of adjustable volume is located on the dispensing end of the fluid injector assembly. The capillary opening of (A) an automated fluid injector, or fluid injector assembly can be loaded with a fluid specimen for subsequent injection via the combination of (B) an injector feed assembly comprised of a probe sub-assembly inclusive of a pair of hollow needles which provide a conduit for the pick up of said fluid specimen from a vial and transport of the fluid specimen to the fluid injector, and (C) a magazine for transporting one or more fluid specimen-containing septum sealed vials for pick up by the pair of hollow needles of the probe sub-assembly for delivery to the fluid injector via thrust of the probe through the septum of a vial, pressuring the contents of the vial by delivery of gas from a source through a first of the hollow needles of the probe sub-assembly to produce flow of fluid specimen from the vial into the second of the set of hollow needles for transport through the probe sub-assembly to the fluid injector.
