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)
