A... Mass spectrometry may be used to measure with high sensitivity trace amounts of an element through the technique of isotope dilution. A trace element is a chemical element whose concentration (or other measure of amount) is very low (a "trace amount"). functions primarily as a carrier for oxygen as part of hemoglobin and myoglobin; important in immune function, cognitive development, temperature regulation, energy metabolism; about 90% in body is conserved and reused . List of Trace Minerals.
