Regulatory changes from the EPA have catalyzed significant innovations in gas chromatography, enhancing analytical ...

Kolkata: At least 14 samples of human remains were sent for forensic analysis to ascertain the number and identities of those killed in a massive fire that gutted two warehouses and an adjacent ...

Large Language Models (LLMs) with Mixture-of-Experts (MoE) architectures are distinguished by their strong performance scaling with increasing parameters across a wide range of tasks. However, they ...

Sample preparation plays a crucial role in bioanalytical analysis involving chromatography. Insufficient sample preparation, such as skipping protein precipitation, phospholipid removal (PLR), ...

Chili powder's complex matrix poses challenges for pesticide residue analysis, requiring optimized LC–MS/MS methods for accurate quantification. Optimized extraction and d-SPE cleanup protocols ...

The analysis shows that volcanic material in the sample contains sulfur compounds that are highly depleted of sulfur-33 (or 33S), one of four radioactively stable sulfur isotopes. The depleted 33S ...

When astronauts returned from NASA’s final Apollo Moon mission in 1972, some of the samples they collected were sealed and carefully stored away in the hope that future researchers using advanced ...
