Semiquantitative Analysis

Semiquantitaive analysis provides an first step analysis of unknown materials or chamicals rather than resorting to a full chemical assay of the contents of a product which is more involved.  This semi-quanitiative approach is more cost effective and often provided sufficient information or at very least guides and targets the work for a full assay.  Example applications include:

  • Determination of complete unknown chemicals, powders and materials by Semi-quantitative XRF
  • Determination of unknown microscopic debris, dust or contaminants by SEM / EDX and FTIR.
  • Unknown organic contaminant by GC-MS or FTIR.
  • Analysis of unknown paint and coating pigments by Semi-quantitative XRF.
  • Total quant ICP-MS of chemicals and materials to provide guide elemental compositions.
  • Quantification of multiple organics within a mixture by GC-MS toluene equivalents.
