A microwave digestion procedure for multi-elemental analysis of food was developed using one program to digest a variety of food matrices at the same time. A single program was enabled by an analytical portion mass based on the food's energy content calculated from macronutrient data (fat, protein a

✦ Synopsis
AIrstract
An experimental arrangement for multi-element microanalysis of solid samples by laser ablation-microwaveinduced plasma optical emission spectrometry is introduced. The application of optical tibres as the interface between an 6chelle spectrograph and a gateable optical multi-channel detector head allows simultaneous measurements of up to ten elements with single laser shots and investigations of element correlations in samples from shot to shot. Correlation measurements of trace elements in steel and ahnninium and sodium and lithium in high-purity quartz are given as examples.
