Document Summary

The boltzmann distribution describes: the relative error of different states at thermal equilibrium, the relative populations of different states at thermal equilibrium. (ground and excited, the relative populations of different states at chemical equilibrium. Icp = ar ionized at high t plasma = partially ionized gas. At these high temperatures, the analyte is not only atomized but also ionized serium atoms emit in the red, while ions emit in the blue. Depending on what looking for look at different places in fllame. Polychromator plasma light is first dispersed in the vertical plane the grating then disperses light in the horizontal plane a charge injection device allows simultaneous detection of all elements. 35 charge coupled devices (ccds) detectors no moving part. Other features of icp-oes negligible chemical interference because of high plasma t. 100% atomization efficiency (even with residence time of 2 ms) ionic emission is more intense (more sensitive) than atomic emission for many elements (ca,
