Full Particle Identification^SM (FPID)

Full Particle Identification^SM (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
