Abstract
A system for injecting sample fluids into an analyzer and processing the analysis data is disclosed. The system includes 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, and a control module for governing and sequencing the operation of the system. The storage module houses a plurality of sample-containing trays which can be loaded with samples remote from the system. A gas operated liquid purging system is employed for minimizing the quantity of residual material injected into the analyzer with successive samples, which system operates over a broad range of purging fluid viscosities using excessive amounts of fluid purge material.
