Rare example of detection limits in the presence of Self Absorption. In this case, self absorption is reduced significantly by collecting the spectra with short delay and integration time so that the population of the ground state is comparatively lower.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes

Element RMSE (ppm) Wavelength (nm) Calibration Method Notes
Mn 0.0096 % 403.3100 Univariate Calibration Roughly 16x improvement in RMSE over other integration times due to reduction in self-absorption
Cu 0.0115 % 327.4000 Univariate Calibration Roughly 3x improvement over other integration time due to reduction in self absorption.
