Immunoassays by flow injection analysis.
A home-built flow injection analysis (FIA) system was fully automated using an Apple IIe microcomputer, and subsequently used as a versatile system for the study of immunoassay procedures. The performance of the automated system was monitored by using the turbidimetric detection of barium sulphate …
