Determination of Metal Impurities in H2O2, HNO3and H2SO4 by ICP-MS
-
摘要: Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect trace metal impurities in reagents such as H2O2, HNO3and H2SO4. The limit of detection to metal elements can be down to 2-20 ng/L in H2O2 and HNO3 and 0.1-1.0 ng/L in H2SO4.Abstract: Inductively coupled plasma mass spectrometry (ICP-MS) was used to detect trace metal impurities in reagents such as H2O2, HNO3and H2SO4.
