Grazing-Angle Fourier Transform Infrared Spectroscopy for Online Surface Cleanliness Verification. Year 1
Abstract
As part of the Online Surface Cleanliness Project, the Naval Facilities Engineering Service Center (NFESC) conducted a study of grazing-angle reflectance Fourier Transform Infrared (FTIR) Spectroscopy as a tool for online cleanliness verification at Department of Defense (DOD) cleaning facilities. NFESC partnered with Sandia National Laboratories, Livermore, California, under the sponsorship of the Strategic Environmental Research and Development Program (SERDP) in the development of two prototype instruments with complementary capabilities for cleaning verification. While Sandia conducted studies on an infrared laser imaging device, NFESC led the effort to develop grazing-angle reflectance FTIR technology into a real-time, on-site device for post-cleaning determination of surface contamination. In the project's first year, the feasibility of grazing-angle reflectance FTIR was demonstrated in the laboratory for the detection of organic contaminant residues on reflective surfaces. Applications where surface cleanliness is critical include coating, plating, and bonding of aircraft parts; bearing refurbishment; and shipboard surface mounting of absorbing tiles. In these cases, visual inspection is often inadequate to detect contamination that will cause subsequent bonding or fouling problems if not removed. The information obtained through this laboratory study is being used in Year 2 of the project to design and build a portable real-time prototype device. This device will allow process operators to analyze parts on site and make determinations of subsequent cleaning actions, as well as aid in distinguishing between specific contaminants.
