Abstract
Abstract A system for injecting sample fluids into an analyzer and processing the analysis data is disclosed. The system comprises a fluid sample analyzer, a sample storage module for a number of fluid samples, an injection module by which samples are injected into the analyzer, a data recording or processing device, and a control module for governing and sequencing the operation of the system. The injection module and the storage module are configured to permit alternate orientations to facilitate horizontal or vertical injection without disconnecting of interconnecting conduits.

Claim 1
Independent Claim
239 words
In a system for injecting fluid samples into a fluid receiver; a. a fluid sample storage module comprising: i. a sample fluid support for a plurality of separate fluid samples, ii. sample fluid extraction means defining a station along said sample fluid support at which fluid is extracted from said sample fluid support; and iii. laterally spaced side walls having a corner intersection, each said side wall defining first and second spaced access means located in the vicinity of said extraction station, said first access means being a hole in said side wall and said second access means being a slot extending to the edge of said side wall; b. an injection module for receiving sample fluid from said storage module and comprising; i. sample fluid injection means for directing a quantIty of fluid into an analyzer; ii. actuating means for controlling operation of said injection means; and iii. at least a wall defining an access opening; c. structure defining a fluid sample conduit extending between said modules for directing sample fluid from said storage module to said injection module through said second access means in a said side wall of said sample storage module and through said injection module access means; and d. connecting means for detachably connecting said modules together with said third access opening aligned with one of said first or second access openings, said conduit structure extending between said modules through said aligned access openings.

Claim 3
Dependent Claim
50 words
In a system as claimed in claim 1 wherein said injection module includes a second wall defining further injection module access means, said injection module access means in each said first and second wall being a hole and a slot, each said slot extending to said injection module wall edge.
