1 Introduction

Industrially produced food products and their primary agricultural products are amongst the best characterized and continuously monitored substances of daily life. Because of the impact of food quality on human health, chemical analysis is demanded by law in most countries. Trace element analysis, e.g. for toxic heavy metals like lead, cadmium or mercury is a routine task in industrial and governmental food testing labs.

In order to demonstrate the excellent suitability of Multiwave 7000 for sample preparation of food and other organic samples prior to element analysis the recovery rates of certified reference materials were determined. The described conditions can be used as a starting point for different kind of organic samples.
