Flow-injection analysis in clinical chemistry.
Flow-injection is the most recent addition to the techniques used in automatic analysis. In the simplest form, the sample is injected as a discrete slug into a stream of reagent flowing in a narrow-bore tube. Various sampling valves have been used in order to achieve full mechanization, but are not ideal for clinical analyses since they are wasteful of sample. An economical alternative has been developed which is based on the precise aspiration of sample by a probe. Applications of FIA and this modification in particular to clinical chemistry are discussed.
