local efficiency of atomization, \(\varepsilon_{\text{a}}\)

in flame spectrometry
The @S06075@ of atomized component in the component consumed. The efficiency of atomization is measured in a given part of the flame, usually the observation space; \(\varepsilon_{\text{a}} = \varepsilon_{\text{n}}\ \chi _{\text{s}}\ \chi _{\text{v}}\ \chi _{\text{a}}\). The signal is a function of the product \(q_{\text{v}}\ \varepsilon_{\text{a}}\), but \(\varepsilon_{\text{a}}\) is also a function of \(q_{\text{v}}\), usually decreasing at high volume rates.
