The flame serves as a sample holder as the light passes. These standards can be used with Agilent and non-Agilent instruments and are available in different formats and concentrations including. A light beam from a hollow cathode lamp or an electrodeless discharge lamp is directed through the flame into a monochromator and onto a detector that measures the amount of absorbed light.

The metal ions are nebulized as a fine spray into a high-temperature flame where they are reduced to their atoms and subsequently absorb light. What is the Impact of Water. PerkinElmer has been a pioneer in atomic absorption spectroscopy AAS since its earliest days from the first ever commercial AA system back in 1961 to the first commercial longitudinal Zeeman graphite furnace AA instrument in 1990 continuing our innovations with the industry-first implementation of cutting-edge real-time double-beam fiber optics in our PinAAcle AA.
