Light from lamp containing heavy metal can pass through heavy metals in solution in flame, so metal atoms absorb light to measure metal concentration {atomic absorption spectroscopy} {absorption flame spectroscopy}. Atomic absorption measures percent absorption. For atomic absorption, concentration can be 10 to 100 parts per million.
