Abstract
The Abbott bichromatic analyzers are the commercial applications of the design concepts of Max Liston, Liston Scientific, Newport Beach, California. Liston conceived the ABA-100 as an ultramicro, single reagent, single channel, simultaneous bichromatic kinetic analyzer in the late 1960’s. This chapter will describe the unique analytical capabilities of Liston’s design and we will, therefore, emphasize the ABA-100 in our discussions. For completeness the reader should realize that Abbott Diagnostics has refined the original Liston design and subsequently introduced three other analyzers which complement the capabilities of the ABA-100. The first of these analyzers was the ABA-50, which contained the same optics and logic as the ABA-100, but was semiautomated and is no longer being manufactured. Major modifications introduced in the ABBOTT-VP included an integral syringe for a second reagent, a diluter capable of detecting liquid levels, logic to calculate results using multiple standards, additional error detection capabilities, and choices of reaction times to allow faster completion of analyses. The newest instrument, the ABA-200, has added flexibility in dilution ratios, times of reagent addition, and calculational capabilities. All these analyzers share many design features and are adaptable to perform a wide variety of spectrophotometric measurements.
