Consumer products manufacturing is a big industry
and identification of materials is a consistent need
throughout the industry. From incoming material
verification to defect or contaminant identification,
there is always a need to positively identify materials.
Oftentimes, especially in the case of defects and
contaminants, the material in question is physically
small, but determining the true identity, and likewise
the source, is key to solving the problem. The faster
the material is identified, the faster the source is found
and the faster the line can get back up and running.
Identification of the “black spot” is often the gating
factor in solving contamination and visible defect
Fortunately, material identification of even small spots
can be accomplished using infrared (IR) microscopy.
By combining the analytical power of a Fourier
transform infrared (FTIR) spectrometer with the
precise focus and spatial resolution of a microscope,
the chemical identity of samples that are barely visible
to the human eye can be identified.
