WebApproach ICP-OES and ICP-MS determinations with caution. ICP-OES suffers from poor sensitivity and spectral interference issues and ICP-MS from the 40 Ar 35 Cl mass … WebBlank counts for mass spectrometers with high resolving power may be 0.1 to 1 c s–1or less. Then the detection limits for ICP-MS with sample nebulization may be estimated theoretically. As an example we take an element with middle mass 89Y (a r= 1): cm= 3 · 89 · 1/4.5 ×104· 1 = 59.3 ×10–4= 0.006 ppb = 0.006 ng mL–1for s
Robust Plasma Conditions for the Analysis of Trace Metals in …
Webferences in ICP-MS and are caused by atomic or molecular ions that have the same mass-to-charge as analytes of interest. Current ICP-MS instrumental software corrects for all known atomic “isobaric” inter-ferences, or those caused by over-lapping isotopes of different elements, but does not correct for most polyatomic interferences. Webhigh-matrix samples are analyzed routinely by cool plasma ICP-MS in semiconductor and other applications high concentrations of mineral acids (e.g. 10% H 2SO 4) 1000ppm high-purity metal digests (e.g. precious metals, Cu, Co, etc.) Same hardware technology and similar operating conditions can be applied to bing new background everyday
