| 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) |
