Copper in seminal plasma: comparison of two processing methods for atomic absorption spectrophotometry.

Fifty-three randomly selected seminal plasma samples were assayed for copper by atomic absorption spectrophotometry. All the samples had undergone two accepted processing methods--wet oxidation and dilution. The results were compared, and a highly significant difference was seen (p less than 0.001). The dilution method gave the better reading and was simpler in processing. The author recommends the dilution method for elemental study in seminal plasma by using atomic absorption spectrophotometry.
