Shimadzu LCMS-8040 for analysis of pesticides in food samples

30 April, 2013

Pesticides and their metabolites are of great concern to society as they are harmful to human health, pollute natural resources and disturb the equilibrium of the ecosystem. Consequently, stricter food safety regulations are being enforced around the world. Triple quadrupole LCMS systems can deliver high sensitivity and identification of the compounds of concern.

Eppendorf offers a full range of spectrophotometers: from the entry-level D30, specifically for DNA, RNA and protein quantitation, to the full-spectrum tuneable, kinetic and scanning systems - the Basic and Kinetic models.

Spectral patterns of benzene dimer finally deciphered

22 April, 2013

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.

What happens when a chemical bond is broken?

09 April, 2013

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.

Is antimatter the result from the Alpha Magnetic Spectrometer experiment?

04 April, 2013
