Go Beyond Standard Tests and Protocols
Count on Exponent for developing custom tests or test protocols to help you understand real-world conditions that aren't captured by standard tests. We leverage our diverse pool of expertise and rapid prototyping capabilities to quickly design and construct custom fixtures and instrumentation.
The broad range of test equipment and facilities that we have — both and Menlo Park and our labs around the world — can be leveraged to provide reliable, real-world validation data.
Exponent uses modeling and simulation to assist in design and failure analysis by evaluating the effects of loads on systems or products. Our interdisciplinary teams apply integrated capabilities to a breadth of scientific and engineering issues. Client projects range from medical devices to satellites to downhole tools for the oil and gas industry.
Exponent utilizes the most advanced software available for finite element analysis (Simulia Abaqus, ANSYS, and LS-Dyna) and fracture mechanics (Franc3D), and maintains a high performance computing cluster for executing simulations. We can tackle any modeling problem, no matter the size of the assembly or the complexity of the materials involved.
Exponent's biomedical engineering laboratories in Menlo Park (in addition to our Philadelphia and Natick, MA labs) are accredited to ISO 17025 by A2LA for evaluating medical materials and medical devices. Some of the core services offered include:
Retrieval analysis to meet total product life cycle requirements
Wear and fatigue of orthopedic, spinal and cardiovascular devices
Biomaterials testing to meet supply chain requirements
Ex-vivo tissue mechanical testing and imaging
Accelerated aging, degradation and shelf-life testing
Mechanical Modeling and Simluation
The mechanical lab team can tackle any modeling problem, no matter the size of the assembly or the complexity of the materials involved. Our facilities enable our team to obtain experimental results to supplement and validate our analytical models. Services include:
- Finite element analysis
- Fracture and fatigue analysis
- Vibration and rotating equipment evaluation
- Material constitutive modeling, testing, and evaluation
- Coupled structural, thermal, and fluid dynamics analysis
- Fluid/structure interaction analysis
Our machine shop facilities and equipment provide capabilities — from machining to structural welding and cutting — for the rapid fabrication of prototype components for products including medical devices, electronics, and more.
Analytical Chemistry Laboratory
This lab is recognized as an ISO 17025 accredited laboratory (A2LA Certificate 2561.03). As applicable, the laboratory testing services are compliant with 21 CFR Part 58, U.S. FDA Good Laboratory Practices (GLP), and the laboratory holds a DEA registration for Schedules I — V.
Gas chromatography-mass spectrometry (GC/MS, TD-GC/MS, both liquid and vapor injection modes)
Ultra-high-performance liquid chromatography-QTOF mass spectrometry (UHPLC/MS, with tandem LC/MS/MS and photodiode array (PDA) detection capabilities)
Gel permeation chromatography (GPC) with refractive index (RI) and light scattering detectors (GPC-MALS)
Fourier-transform infrared (FTIR — transmission and ATR)
Access to Raman and other spectroscopic instrumentation
Scanning electron microscopy (SEM)
Focused ion beam/transmission electron microscopy (FIB-TEM)
Non-destructive 3-D X-ray computed tomography (microCT)
Water content: Karl Fischer (KF) titration
Glove boxes for reactive or air-sensitive chemistry
Extractables and Leachables Testing per ISO 10993-18
Exponent routinely performs extractable and leachable protocols for a variety of materials in accordance with ISO 10993-18 and GLP support as required. Simulated-use, exaggerated, and exhaustive extractions can be conducted on devices or components to identify the quantities of the isolable material present. The analytical data produced can support toxicological risk assessments on components of concern by one of our in-house toxicologists or can be provided directly to the client for their own analysis.
Purity and Contamination Assessment
Our staff has extensive experience conducting purity assessments of pharmaceutical compounds in compliance with compendial methods (United States Pharmacopeia, USP) via UHPLC under GLP as required. We also have capabilities for developing and validating non-compendial and other custom methods for challenging matrices.
Since contamination can occur on surfaces and in products across many industries, we are prepared to assist clients when downstream contamination issues arise — whether at the formulation-level in products such as cosmetics, adhesives, and lubricants, or the system-level, at bonded interfaces, in assembled devices, on printed circuit boards, and elsewhere.
Our experts have assisted clients with quality assurance (QA/QC) test method validation to ensure that SOPs are properly developed and implemented. In addition to onsite manufacturing audits, we can assist in the verification and implementation of existing methods, either during technology transfer matters or other instances where analytical method adaptations are needed.
SCOPE OF ACCREDITATION TO ISO/IEC 17025:2017
