Analytical Instruments
Sample preparation reduces sample complexity and renders samples into a format amenable to downstream analysis. Sample prep is most necessary for complex, multicomponent samples containing substances that interfere either with the MS (e.g., through ion suppression) or, in GC/LC-MS, the chromatography.
Pharmaceutical and biotechnology companies have become leading MS customers. Because they work with human and test animal biological fluids and low-dose drugs, sample preparation takes center stage. Many of these workflows are automated for both sample and standards preparation.
MS originated as a stand-alone technique for volatile compounds. Next came the ability to volatilize high molecular weight materials through heating. The emergence of electron-impact ionization MS was a natural, as GC analysis requires volatilization. Find out what the future of MS holds.
In this month’s edition of INSIGHTS, our panel of four experts discusses the types of MS analyses and experiments they run and the top factors they consider when buying MS instrumentation. We also explore the trend of the shrinking mass spectrometer in a Q&A sidebar with 1st Detect president and CTO Dave Rafferty.
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
