What is Trace Analysis?

Some analysts refer to trace analysis as a measurement below one ppm (µg/g) while others use the term to describe an analyte concentration low enough to cause difficulty. This difficulty may be caused by the sample size or the matrix (i.e. - the concentration of the analyte of interest relative to the matrix or the sample size causes difficulty for the analyst). Most trace analysts using ICP-OES / ICP-MS prefer the latter definition. Regardless of which definition you prefer, most analyses that require a measurement using ICP-OES or ICP-MS fall within the category of trace analysis.
