SGS PSI is an independent materials testing lab for analysis of your polymers, plastics, and organic and inorganic substances. SGS PSI is an ISO 17025 accredited lab. We are cGMP compliant, FDA registered, and DEA licensed. We are also capable of providing ITAR compliance for your projects.

SGS PSI can assist you with your material testing needs through physical testing and chemical analysis.

Aging & Chemical Resistance Testing

We can help you establish a protocol to assess your materials’ response to relevant aging conditions and chemical exposures.

Bioabsorbable Polymer Testing

PLA, PGA, PCL, and their copolymers are commonly used in resorbable medical devices. We have a variety of methods in place for resorbable polymers. We can also develop and validate customized methods for your unique material and application.

Food Contact Testing

Title 21, Part 177 CFR testing covers polymer materials that come into contact with food. The sections of the CFR are divided by material type and application. We have performed CFR testing on materials such as rubber, polyethylene, polycarbonate, polyolefin, and nylon.

Contamination Analysis

Contamination in products can cause a variety of problems which can lead to product failure, undesirable aesthetics, or quality control failure. Fourier transform infrared spectroscopy (FTIR) can identify organic contaminants. Scanning electron microscopy with energy dispersive spectroscopy is a method that can detect inorganic materials. Gas chromatography is a method that can be used to detect volatile and semi-volatile contaminants. We can use these and other necessary methods to detect contaminants in your materials.

Deformulation and Competitor Product Analysis

Using several techniques, we can often deformulate, or reverse engineer, a product. This is usually a multi-step process. The typical first step is to screen to identify the components. Once the initial screening is completed we can then quantify those components.

Film Layer Analysis

Film technology is important in many industries including the packaging, medical, and food industries. We have several methods that are typically used in film layer analysis. We can determine how many layers comprise the film, the thickness of those layers, and elemental composition of the layers. We can also determine the cause of delamination as well as adhesion properties.

Medical Device, Products, and Packaging Testing

SGS PSI can offer many testing methods for your medical device, product, or medical packaging material. Some of the ways we can assist you in testing your medical products are chemical composition, extractables and leachables, lot release testing, FDA submission testing, and risk assessment.

Molecular Weight Analysis

Molecular weight can affect the properties of a polymer during processing and end-use. It is also a good indicator of changes as the polymer goes through its various stages such as raw material, molding, sterilization, and storage and end-use. We have several methods for determining the molecular weight distribution of your polymer including inherent and intrinsic viscosity, melt rheology, melt flow index, and gel permeation chromatography (GPC). GPC, or size exclusion chromatography (SEC) will provide the most information about the molecular weight properties of a polymer. For most polymers we can provide relative or absolute molecular weight determination utilizing GPC.

Residual Monomer Analysis

Determining the residual monomer content of polymers is important because some monomers are toxic, or they can lead to accelerated polymer degradation. SGS PSI can quantitate residual monomer content using gas chromatography with either flame ionization detection (GC/FID) or coupled with mass spectrometry (GC/MS).

RoHS Testing

The European Restriction of Hazardous Substance Directive (RoHS) places limits on the following substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), bis(2-ethylhexyl) phthalate (DEHP), benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DiBP). We can screen by X-ray fluorescence spectroscopy (XRF) according to ASTM F2617. The presence of phthalates is screened using either GC/FID or GC/MS.
