ABSTRACT:
A system for providing a spectrophotometric analysis of a plurality of fluid samples, the system including a spectrophotometer having a low pressure flow cell and an automatic injector device which stores the fluid samples without exposure to the atmosphere and injects the samples successively at low pressure into the flow cell where they can be scanned to produce scanned data for processing. The system prevents the scanning of each fluid sample until the injection thereof has been completed, the processing of scanned data for each fluid sample being performed substantially simultaneously with the injection of the next successive fluid sample into the flow cell.
