How does ICP-MS Improve Productivity and Profitability in the Environmental Laboratory?

Recent developments in ICP-MS have extended its applicability well beyond clean environmental sample types such as drinking water. More complex and variable sample types such as wastewater, soil and sediment digests and other environmental matrices with high levels of total solids are now routinely analyzed. This presentation will discuss hardware choices and optimization approaches that maintain high productivity and ensure quality data when analyzing difficult matrices.

Gold too? Ions in the +II oxidation state

thumbnail image: Gold too Ions in the II oxidation state

When it comes to atoms there are several seemingly immutable facts about many of them - their oxidation states or valencies are seemingly fixed. However, whereas gold is generally considered to exist as only gold(I) and gold(III), theoretically, a 2+ oxidation state should exist to fill the gap in the homologous series of the coinage metal ions copper(+II), silver(+II), gold(+II), and in the "relativistic" triad of platinum(+II), gold(+II), and mercury(+II). That gap has now been filled as chemists isolate...

Current knowledge surrounding the use of MC-ICP-MS and other geochemical methods in vertebrate palaeobiology has been reviewed, including a case study involving two mammal assemblages from the Pleistocene of Europe.

How does ICP-MS Improve Productivity and Profitability in the Environmental Laboratory?

Date: Nov 1, 2017 - 14:00

Recent developments in ICP-MS have extended its applicability well beyond clean environmental sample types such as drinking water. More complex and variable sample types such as wastewater, soil and sediment digests and other environmental matrices with high levels of total solids are now routinely analyzed. This extension of the scope of ICP-MS applications brings its own challenges. Methods must address the high matrix loading on the instrument, and the potential for matrix elements to cause polyatomic...
