Organic Analysis:

Unlike soils which can effectively be extracted by ultrasonic disruption of a soil/solvent mixture, tissues require a more exhaustive, soxhlet extraction.

Analysis of samples is done according to Pace’s Standard Operating Procedures (SOP), derived from EPA methods noted in the above table.Inorganic Analysis:

Tissue samples may require metals analysis by:

  • Inductively Coupled Plasma Mass Spectrometry (ICPMS)
  • Cold Vapor Atomic Absorption (CVAA)
  • Cold Vapor Atomic Flourescence (CVAF)
