Abstract
Methods and systems of identifying two or more elements in a single individual particle are described. In some examples, an optical emission from each of an ionized first element and an ionized second element can simultaneously be detected to identify at least a first element in a particle from a plurality of particles using the optical emission from the ionized first element, and to identify at least a second element in the particle from the plurality of particles using the optical emission from the second ionized element. The identified first element and the identified second element can be used to identify a source of the particle from a plurality of particles.
Claims20
A method comprising:
- ionizing a sample comprising a plurality of particles, wherein the plurality of particles comprise a particle comprising a first element and a second element, and wherein ionization of the sample provides excited, ionized first element and excited, ionized second element;
- simultaneously detecting a wavelength of an optical emission from each of the excited, ionized first element and the excited, ionized second element to identify at least the first element in the particle from the plurality of particles using the optical emission from the excited, ionized first element, and to identify at least the second element in the particle from the plurality of particles using the optical emission from the excited, ionized second element;
- and
- using the identified first element and the identified second element to identify a source of the particle.
