Description:
The use of furnace atomic absorption instrumentation with a turnkey chromatography data system is described. A simple addition of relays to the furnace power supply allows for automatic start-up of A/D conversion and spectrophotometer zeroing at the proper time. Manipulations involving editing, sorting and averaging of up to 250 atomization signals in an analysis run were accomplished by developing a procedure employing BASIC language programming techniques. The same dedicated data system was employed for all steps and post-run data processing, conveniently accomplished in 5-15 minutes, gave a tabulation of sample name, mean concentration, standard deviation, number of analyses, and percent recovery.
