Abstract

Abstract The instrumental system described [Clin. Chem.19, 1114 (1973)] is evaluated in manual, partially automated, and totally automated modes to measure system and individual component performance. Excellent accuracy and precision were observed, hence the system is judged suitable for most analytical applications. Results are: wavelength accuracy and reproducibility in automated mode: ±0.004 nm and ±0.1 nm, respectively; photometric accuracy and precision: ca. 0.8% relative and ±0.007 A, respectively, in both the manual and automated modes; and ratemeter accuracy and precision: ±0.4% relative and ±0.873 (SD) mV/min (or mA/ min), respectively, for standard synthetic ramps and ±1.2% relative and ±2.2 (SD) mV/min, respectively, under actual laboratory conditions for rates in the range of 1 to 200 mV/min. Automated experiments are made without human intervention after the samples are loaded.
