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 ...

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 ...

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 ...
