A Deep Dive into Dynamic SIMS vs. static-SIMS
Different types of SIMS analyses exist. The two main types include Dynamic SIMS (high current) and static-SIMS (low current).
Polymer Case Study: Off-Odor Memory Foam
One of the most sought-after products in the bedding market, memory foam can be found in mattresses, pillows, and more. Memory foam contours to body shape and is popular due to its combination of comfort and support.
Case Study
A client requested analytical testing to support changes in raw materials and processing conditions used in manufacturing their commercial foam material. The client wanted to assess differences in the physical characteristics of the foam as well as the volatile sensory profile experienced by consumers.
Analysis
To address the sensory concerns, a matrix of foams formulated under slightly different conditions were qualitatively screened for volatile organic compounds (VOCs) using headspace GC-MS.
The foams were then compared in terms of relative amounts of specific target compounds that were associated with a specific odor description, such as “musty” or “fishy”.
Result
The analytical testing allowed the engineers to correlate mechanical performance with the odor profile and to optimize the formulation.
Failure Analysis of Polymers
For more than 50 years, scientists and engineers at Eurofins EAG have investigated and resolved product failures for clients. Our team of experts identify key failure indicators and follow them to the root cause.
Polymeric Materials Evaluated at EAG
Failure analysis of plastics, thermosets, and rubber materials is commonly performed on finished products and typically involve comparative analysis between failed and non-failed samples. Once the potential root cause is identified, experiments can be designed and conducted to test the hypothesis and recreate the failure in the laboratory. Eurofins EAG can evaluate a variety of polymer types, including:
- Raw materials in polymer formulations
- Adhesives (heat/moisture/UV-cured, silicones, epoxies, acrylates)
- Coatings (functional or decorative)
- Thermoplastics, thermosets, thermoplastic elastomers, composites
- Molded, extruded, cast components
Eurofins EAG Laboratories offers a full suite of analytical techniques to evaluate the identity, composition, morphology, topography, and rheology of polymeric materials and components.
