A spectrum of the benzene dimer was first recorded in 1993, with the aim to find out more about its structure and dynamics. The experiments produced characteristic patterns with four peaks, which no one could decipher for 20 years. Now, using a new theoretical model and the experimental data gathered in Berlin, the spectral patterns have been successfully deciphered and the dynamics that cause them explained.
That question was recently answered with the help of a so-called free electron X-ray laser, which makes it possible to follow in real time how bindings in a molecule are changed and broken. The study, published in Science, found, among other things, evidence of a much-discussed intermediate state before molecules bind to or leave a metal surface. The possibility of monitoring at the molecular level how the electron structure changes in a chemical reaction creates entirely new opportunities for investigating and understanding key chemical processes in detail.

Driving high sensitivity in biomolecular MS: improving this key parameter enables novel applications and powers additional techniques.21 November, 2012 by Bruce Thomson, Chief Scientist, AB SCIEX
Mass spectrometry has become a key tool for the analysis of biomolecules in applications that range from discovery of biomarkers to the analysis of drug metabolites. While many of the analytical benchmarks of the mass spectrometer - limit of quantitation or LOQ, signal-to-noise or S/N, dynamic range, mass resolution - are important for these applications, the absolute sensitivity is a key factor that drives these characteristics.
