Full Particle IdentificationSM (FPID):


FPID is a continuation of the OPID analysis. The

process begins with an OPID to identify the particles

in the analyte list. Then the remaining unidentified

material is analyzed by electron microscopy. In many

cases infrared spectrometry (FT-IR) or X-ray

Diffraction Spectrometry (XRD) is also utilized. This

test is designed to identify the majority of materials

commonly occurring in indoor environments. The

standard analytes included in the FPID include:

  • Everything from the OPID list
  • Minerals, metals and oxides such as rust
  • Construction debris such as gypsum, mortar and wood dust
