摘要：

A simple and versatile variable-volume injector is described for the introduction of samples in flow-injection systems. The device delivers precisely and reproducibly (usually r.s.d. < 0.9%) 4-62-μl volumes of sample and is simple to assemble. Examples of applications include the generation of a family of calibration graphs of varying sensitivity covering an extended concentration range for the analysis of real samples. The construction of a calibration graph from a single standard solution is also possible. This is useful in the routine analysis of samples with widely varying analyte concentrations. © 1990.
