Event Overview:

Trace inorganic analysis is an essential part of the analytical testing world. In many cases, contamination can alter or skew elemental analysis providing inaccurate results. In this webcast, the sources of contamination and methods of controlling error will be discussed with practical best practices for inorganic trace analysis.

Key Learning Objectives:

  • Understand the ways and routes in which contamination can enter inorganic samples and how to eliminate or control those sources
  • Review best practices for common laboratory sample preparation and dilution techniques used in inorganic sample preparation to reduce contamination and error
  • Learn the appropriate calculations and use of inorganic reference materials and how to translate common conversions to reduce calculation errors

Who Should Attend:

  • Elemental spectroscopists working with AA, ICP, ICP/MS, IC, and other elemental techniques
  • Analysts working in the elemental or inorganic analytical laboratory
