An automated chemistry analysis method is disclosed. In one general aspect, the method includes receiving a modular chemistry analysis test unit that includes one or more vessels for one or more reagents, and a machine-readable test specification coupled with the vessels. The method also includes defining a test that defines a test including a series of operations that employ the reagents for the vessels, and installing the chemistry analysis test unit in a first chemistry analyzer that includes one or more analysis tools and sequencing logic for sequencing instructions to be carried out by the analysis tools. The machine-readable test specification is automatically received from the chemistry analysis test module and stored for access by the sequencing logic to allow the sequencing logic to instruct the analysis tools to carry out the test defined by the test specification.

Modular chemistry analyzer

A chemistry analyzer is disclosed that can include a unitary base with vertical and horizontal supports for constraining subassemblies. The subassemblies include at least a reagent/sample carousel subassembly, a transfer arm subassembly, and a reaction carousel subassembly. A centralized hydraulic system can also be provided behind a user access panel. The analyzer can use machine-readable test specifications coupled with its reagent vessels to define tests that include operations that employ the reagents. The analyzer can also display to the operator a pictorial representation that includes graphical elements that convey levels of usage for the storage vessels, and access icons that are each associated with a color and each lead to a set of screens for different types of operations for the analyzer.

A modular automated diagnostic analyzer having a fluid entry module for sample aspiration, a valve module for selecting fluids and a pump module for fluidic movement so that a biological samples does not come into contact with the valve system through which calibrants and air are introduced to the fluid path. The fluid entry module encloses an aspiration tube rotatably and slidably engaged with the analysis mechanism chassis to move to different positions for the introduction of fluids into the analysis apparatus from different types of sample containers. A wiping seal removes residues of aspirated fluids from the exterior surfaces of the aspiration tube with the residue being aspirated into the analysis apparatus for disposal. Sensor modules mounted in a sensors chamber are structured to mechanically stack and interlock and include film sensors with use life record memories and each sensor module includes a fluid tight sealed passage and a sensor element. A fluid selection valve of highly polished ceramic material allows a valve cylinder passage to be selectively connected to fluid sources. A self-contained reagent pouch housing contains calibrants including tonometered calibrants in reagent pouches wherein each pouch wall includes multiple layers of materials wherein at least one layer is a thin, flexible glass material. The walls are extended to form a filler neck sealed by heat and pressure along a sealing line below a filler line so that no bubbles are trapped in the reagent pouch.
