The measurement of polydisperse nanoparticles in the region from 10 nm to 1000 nm in liquid is a challenge. Traditional light scattering methods such as dynamic light scattering (DLS), while being excellent for monodisperse samples, tend to skew results to larger sizes (and numbers).

One trend evident in science generally, and for laboratories in particular, is the desire to do things faster, more reliably and economically, at a higher level of hardware and method robustness, and all with a less-specialized workforce. This is especially true of mass spectrometry, where users no longer need a Ph.D. to operate MS systems.

According to one expert, the top service-related issue today is an unintended consequence of instrument sensitivity and stability

Bruker Chemical and Applied Markets (CAM), Fremont, California, US: Bruker has released an Application Note detailing the development for analysis of microcystins in drinking water, by direct injection on the recently introduced EVOQ Elite liquid chromatography mass spectrometer triple quadrupole (LC-MS/MS).

An end user shares how her company uses mass spectrometry and how she went about selecting the MS systems in her facility in a brief Q&A.
