AN43098: Speciation analysis of Cr (III) and Cr (VI) in drinking waters using anion exchange chromatography coupled to ICP-MS

Instrument Type: IC

Speciation determinations of ionic compounds are important to determine the concentration of the more toxic form in the total elemental composition. Chromium is an industrial waste contaminant that can have serious health effects and therefore requires monitoring in municipal water systems. This method determines Chromium VI and Chromium III species in a municipal drinking water sample. The ions are separated by ion chromatography (IC) on an IonPac AG7 guard column and detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) at ng/g. This method is further optimized in AN43175.

AN43175: The Migration of Elements from Toys and Speciation of Chromium (VI) in Toy Material Using a IC-ICP-MS Solution

Instrument Type: IC

Speciation determinations of ionic compounds are important to determine the concentration of the more toxic form in the total elemental composition. Chromium compounds have brilliant hues and consequently are often used in dyes and inks however, chromium compounds are toxic. Chromium VI species is very toxic so it is monitored as an extractable in children’s toys. This method determines extractable Chromium VI (SOP EN 71-3:2012) in an ink sample separated by ion chromatography (IC) on IonPac AG7 guard column and detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) at ng/L.
