Addressing Product Failure and Customer Complaints with PSI’s Expert Team

Let us assist you in your quest to minimize product failures and customer concerns using the following analytical techniques:

Molecular weight degradation during processing can be investigated using:

Gel Permeation Chromatography: Molecular weight is a key parameter determining the functional and material properties of polymers used in a wide variety of applications including medical implants, packaging, injection molded parts, adhesives, and coatings. Intrinsic Viscosity: By measuring the flow time of a polymer solution through a precision capillary, we can measure the viscosity which relates to molecular weight. This is a rapid technique that is very cost effective.

SEM and Optical Microscopy can be used to investigate broken and/or failed parts due to cracking or crazing:

SEM of ductile pipe fracture

SEM/EDS: SEM can be used to image a defect on the surface of the part and identify the source of the defect as a contaminant by its elemental composition (determined by EDS). Optical Microscopy: Optical microscopy is often the first technique used to examine or compare products or prepare small samples before further analysis is performed and is often used to document sampling sites or phenomenon encountered during other tests.

Fourier Transform Infrared Spectroscopy (FTIR) can determine the base polymer composition of a device or film:

FTIR Spectra of multilayer film

FTIR: Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It can be used to identify compounds or investigate sample composition.

Gas Chromatography/Mass Spectrometry (GC/MS) can identify trace components in complex mixtures:

Residual Monomer Detection via GC/MS

GC/MS: Applications of GC/MS include identification of unknown samples. Analysis of volatile or semi-volatile compounds can be achieved using headspace techniques or extraction and liquid injection techniques. Quantitative analysis to part-per-billion (ppb) levels can be accomplished.
