Measurement by flame photometry involves
Webphotometry the measurement of the intensity of light without regard to wavelength It is used to measure the light transmitted by a solution in order to determine the concentration of light-absorbing substances in that solution. How is a spectrophotometer used in clinical chemistry? concentration logarithm WebTypically, the choice measurement methods are, flame photometry (Hald 1947) or ion selective electrodes (Fogh-Andersen et al. 1984; Levy 1981). While both of these methods give consistent and reproducible results, they are limited in that they are usually exclusive for single ions per sample and require larger sample volumes.
