| The amounts of iron, copper, and zinc in several different brand name and generic multivitamin tablets (real world samples) were determined by flame atomic absorption spectrophotometry. Sample preparation procedures are outlined and instrumental operating conditions are specified. Statistical analysis was applied to determine if the obtained results differed significantly from the values stated on the tablet containers. This experiment forms part of laboratory exercises for the atomic spectrometry portion of an instrumental analysis course. |
