| Abstract: | Seven different types of foodstuff (containing 3-100 ppm Zn) were each analysed for zinc by colorimetry, polarography and atomic-absorption spectroscopy. All the techniques yielded similar values for the zinc content of a given sample, but atomic-absorption spectroscopy had a smaller average coefficient of variation. |
