The “rockets’ red glare” may light up the night sky, but what exactly is left behind when the smoke clears? LECO tested water at a fireworks display site for environmental contaminants. The GCxGC-HRMS data revealed environmental impacts hidden within the holiday’s celebrations.
Recently, the chemists at LECO took on the challenge of characterizing the chemical makeup of a high-performance polymer known as polyphenylene sulfide, or PPS. Using thermal desorption, pyrolysis, and HR-TOFMS, they were able to get an accurate and thorough chemical fingerprint of PPS.
A whey protein shortage is causing companies to have to reformulate their protein-boosted products amidst the protein craze. Testing to ensure these reformulations meet protein expectations is crucial.
As battery materials continue to evolve, analytical approaches must provide both high sensitivity and high confidence identification. A recent LECO application study demonstrates how combining two GC-MS platforms enables a more complete characterization of DMC impurities than either approach alone.
For quality assurance, metallography can be used to assess the porosity, grain structure, and more of an aluminum sample. By analyzing a sample, manufacturers can determine whether the aluminum will meet performance and quality expectations and resolve any issues.
Biomass feedstocks and finished fuels must be carefully analyzed to ensure quality, efficiency, and compliance with international standards. LECO analytical instrumentation supports this work through automated and highly reliable analytical technologies.
Testing the adhesive is paramount for quality control of wood composites. Testing for nitrogen and carbon levels specifically will give producers the data they need in order to ensure their product meets performance expectations and regulatory requirements.
