Rare paper measuring noble gas concentrations in other gas mixtures (rather than using the He or Ar as a buffer gas for other analysis). Detection limits are strongly dependent on the gas mix.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Ar 4.9000 (Calibration Curve Slope) 763.5100 N/A Univariate -10.0000--10.0000 Detection limit for Argon in Helium. LODs in the range 4.6-270ppm depending on main diluent gas (Nitrogen, Helium)
He 46.0000 (Calibration Curve Slope) 587.5600 N/A Univariate -10.0000--10.0000 Helium in Nitrogen. LODs in the range 46-160ppm depending on diluent gas (Nitrogen or Argon)
