Analytical instrument systems, components, and methods for stabilizing discharge formation are described. A spark gap device includes a first planar coil, defining an axis normal to a coil plane and defining a first aperture substantially centered about the axis. The spark gap device includes a second planar coil, offset from the first planar coil along the axis and substantially parallel with the coil plane, the second planar coil defining a second aperture substantially centered about the axis. The spark gap device also includes a conductive element disposed in the first aperture and substantially aligned with the axis.

Magnetic confinement of arc discharge migration in spark OES systems

A method for compositional analysis includes providing a sample having a surface, moving an ablation point to a plurality of positions on the surface along a fractal path, pulsing an energy source to provide an electromagnetic energy beam to ablate material at the ablation point, collecting an emission spectrum in response to pulsing the energy source, and analyzing the emission spectrum to determine a composition at the surface.

Systems and methods for performing laser-induced breakdown spectroscopy

A multipass cell () comprising: a first reflector arrangement (A,B); and a second reflector arrangement (), the first (A,B) and second () reflector arrangements defining an optical cavity () therebetween and the cell; wherein the first reflector arrangement (A,B) is configured such that light incident on the first reflector arrangement (A,B) is at least partially retroreflected towards the second reflector arrangement (), wherein the second reflector () arrangement comprises a concave surface that is reflective, wherein at least one of the first (A,B) and second () reflector arrangements comprises an aperture () for allowing light to enter and/or exit the optical cavity ().
