WebApr 13, 2024 · The basis of flame photometric working is that, the species of alkali metals (Group 1) and alkaline earth metals (Group II) metals are dissociated due to the thermal energy provided by the flame source. Due to this thermal excitation, some of the atoms are excited to a higher energy level where they are not stable. WebPhotometric linearity is a measure of the linearity of the measured values (e.g. absorbance) as a function of increasing concentration. This is especially important for quantitative …
WebThe photometric telescope In addition to the main telescope, the SDSS uses this 0.5-meter Photometric Telescope to monitor subtle changes in the atmospheric temperature and pressure during the course of the survey. This information allows astronomers to calibrate an object's brightness as measured with the main telescope.
