NASA has finally shared details about the first analysis of samples taken from the asteroid Bennu using the OSIRIS-REx spacecraft in 2020. While NASA scientists are still working on documenting the ...

X-Ray photoelectron spectroscopy (XPS) is one of the most important and widely used methods for determining surface chemistry of materials. Cryo-XPS, where the sample is cooled to temperatures below ...

Early analysis of the asteroid Bennu sample returned by NASA's OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as ...

Recent advances in analytical chemistry have markedly enhanced the characterisation of petroleum and oil samples. With the increasing demand for precise quality control and environmental compliance, ...

Four principal methods govern the preparation of samples for XRF analysis, each representing a different trade-off between analytical quality and speed/cost of preparation. A method involving the ...

Mass spec–based methods coupled with chromatography separation techniques are fundamental to success in proteomics research and biopharmaceutical development, and low-flow liquid chromatography has ...

A sample from the asteroid Bennu, collected by the OSIRIS-REx mission, has arrived at London's Natural History Museum for analysis. Scientists are optimistic that it could contain the seeds of life.

Selected ion flow tube mass spectrometry (SIFT-MS) greatly simplifies quantitative analysis of volatile nitrosamine impurities in drug products. It provides a three-fold throughput advantage and ...
