A convenient and a rapid technique is introduced to estimate the electron number densities, n e , in inductively coupled plasmas. The method is based on previously reported observations that the principal quantum number of the last discernible line in a series limit depends on n e . The spatially integrated n e values, as determined from the spectra of H, Li, Mg, Al, Ca, and K emitted in a pure Ar plasma ranged between ∼4 × 1014 and ∼3 × 1015 cm−3 for various forward powers and observation heights. These results agreed with n e values derived from other methodologies such as the Stark broadening and absolute continuum intensity.
