rate of fluid consumption, \(q_{\textrm{V}}\)

in flame emission and absorption spectrometry
https://doi.org/10.1351/goldbook.R05151
The volume of fluid consumed by the nebulizer divided by time (in \(\mathrm{\mathrm{\mu} L}\ \mathrm{s}^{- 1}\)). @CT01101@ has also been called volume flow, flux, aspiration rate, aspiration flow or aspiration flux. The fluid consumed is either aspirated or injected. The @CT01101@ of fluid consumption by nebulizers is usually between \(10\ \) and \(100\ \mathrm{\mathrm{\mu} L}\ \mathrm{s}^{- 1}\).
