Industry: Consumer Products & Plastics
Problem:
Consumer product supplier needed to determine if Bisphenol-A (BPA) was present in their final products: polymer containers, lids, and storage bags.
Solution: 
BPA Testing - read full case study

Industry: Medical Device
Problem:
Medical device manufacturer needed to know if alternative machining and molding processes were altering mechanical properties of R&D products at the wear surfaces.
Solution:
IA identified and applied a chemical process to stabilize the material and clearly stain the micro-phase domains. TEM images of cross sections afforded direct comparison of surface and bulk morphologies, enabling informed evaluation of manufacturing processes.

Industry: Plastics
Problem:
Manufacturer of precision polyurethane foam polishing pads for the semiconductor industry needed a method to measure cell size and open cell area for quality control, as well as for comparison with competitive products.
Solution:
Impact modified an existing optical microscopy ASTM method, for measurement of the cell size of the micro-porous PU foams in the scanning electron microscope. Impact developed a method for comparative measurement of the percent of open cell area of the polishing foams.

Industry: Food Packaging
Problem:
Manufacturer of multi-layer films for the food packaging industry needed to measure the thickness of layers for quality control. The customer also desired measurement and identification of the layers used to construct competitor's products.
Solution:
Impact used a combination of polarized light microscopy and infrared microscopy to photograph, measure, and identify the separate layers of the film in cross section.

Industry: Plastics
Problem:
R&D team needed to test the success of surface modifications to a particulate additive, by characterizing the adhesion of the additive to the surrounding epoxy matrix.
Solution:
Impact photographed the fractured surfaces of the samples at high magnification in the scanning electron microscope, to clearly document the difference in surface adhesion as a result of experimental modifications. Results enabled the team to pursue a modification technique producing consistently superior surface adhesion of the particles to the matrix, as verified by IA microscopy data.

Industry: Consumer Products
Problem:
Ink Jet cartridges plugging prematurely.
Solution:
Cartridges for ink jet printing were plugging before the ink was consumed. Rejects and returned product were increasing. Disassembly and microscopic evaluation of the cartridge components revealed contaminant fibers collecting on the cartridge filter screens. Characterizing the fibers aided in determining the source. The ink manufacturer was able to make adjustment to the ink processing and eliminate the problem.
