Abstract

Little is known about the amount of water and ash in brazilian foodstuffs and plants. The relationships between fresh, dry and ash weight were determined in 40 different biological samples. It could be an important tool when one studies biological material containing low concentration of the chemical elements. This study address to determine these relationships and to provide the amount of biological material that one needs to collect. It aims to supply information that could be used to improve the detection limit, precision and accuracy of the analytical methodology utilized.
