FTIR Application Case Study: Medical Device Fiber Analysis
A medical device company submitted a sample of fibers that were found in their plastic packaging trays. The particular medical device contained a critical valve that would not operate correctly, if fibers were to enter into it.
FTIR testing, using a microscope attachment, was employed for the fiber testing.. With the microscope attachment, samples as small as 10 microns can be analyzed. This allows for quick and cost-effective identification of the fibers.

Step 1: The unknown fiber was identified by searching the spectrum against a database of reference spectra.
Step 2: The FTIR testing produced a spectrum that identified the fiber as being a cellulose-based cardboard. The medical device company traced the fibers back to cardboard dividers that were being used in their processing line.
Step 3: As a result of the FTIR testing, they replaced the cardboard dividers with polymer based dividers that would not produce any fibers.
