Abstract
A simple and flexible time-based injector is described for the introduction of almost any desirable volume of sample and reagents in flow systems. The feasibility of application is demonstrated by improving the azomethine-H spectrophotometric method for the precise and accurate determination of boron in soil and coffee plant tissues. On-line programmed functions include: sequential injections and zone trapping, with a significant reduction of sample and reagent consumption.
