Techniques {emission spectroscopy} can detect emitted light. Emission spectroscopy can measure amounts of 80 metallic and metalloid elements in minerals, paint, air pollution, water pollution, and oil. Emission spectroscopy produces spectra in UV-visible range. AC spark is more intense and quantifiable. Laser can measure tiny impurities. Quartz tube with microwave coil can make inductively coupled plasmas.
problems
Emission spectroscopy has matrix effects and non-linear results. Emission spectroscopy detects the most-intense spectrum lines, which are also the most wandering. Emission spectroscopy is destructive, because DC arc ionizes metal atoms.
