Key Terms

Mass Spectrometry
A technique that measures the mass-to-charge ratio of ions.

Example: Used to identify the composition of a sample.

Chromatography
A method for separating mixtures into their individual components.

Example: Gas chromatography is used for analyzing volatile compounds.

X-ray Fluorescence (XRF)
A technique that determines the elemental composition of materials by measuring the fluorescent X-rays emitted.

Example: XRF is used in mining to analyze ore samples.

Isotope
Variants of a chemical element that have the same number of protons but different numbers of neutrons.

Example: Carbon-14 is an isotope used in dating ancient organic materials.

Geochemical Analysis
The study of the chemical composition of Earth materials.

Example: Geochemical analysis helps in understanding soil fertility.

Elemental Composition
The types and amounts of elements present in a sample.

Example: The elemental composition of a rock can indicate its origin.
