title: Temperature-programmable furnace for ashing of foods in trace metal analysis.
abstract: The use of programmable furnace in preparing samples for determining cadmium, lead, copper, and zinc by differential pulse anodic stripping voltammetry or atomic absorption spectrophotometry is convenient and time-saving. Recovery data for these 4 metals in various foods (tuna, sardines, and milk) were 93-96% for 0.01-1 ppm cadmium, 96-114% for 0.05-5 ppm lead, 100-108% for 2-10 ppm copper, and 97% for 10 ppm zinc.
