Green is Good

It’s the week before Easter, but outside my window there are still patches of snow on the ground. To which I say, enough already! Bring on Spring and make it snappy.

Business Management

Shopping Around

The acquisition of equipment is a strategic business and operational decision that balances technology, durability, reliability, active running time, purchase price, maintenance, service, and running costs with the value the acquisition could potentially deliver for a laboratory enterprise.

Innovations in Cell Culture: Cells, Reagents, and Assays

Scott Martin, Ph.D., team leader for RNA interference (RNAi) screening at the National Institutes of Health, Center for Advancing Translational Sciences, talks to contributing editor Tanuja Koppal, Ph.D., about recent trends in the use of different types of cells and reagents for screening drug targets and cellular pathways.

Are You in the Market for a Fume Hood?

One of the primary safety devices in laboratories where chemicals are used is the laboratory fume hood. It allows a researcher to work with—but not be exposed to— materials that create toxic fumes or particles when it is properly installed and maintained.

2013 Centrifuge Product Survey Results

When it comes to common technology in a laboratory, centrifuges rise toward the top of the list. Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning and play a role in a wide range of workflows and applications.

Measurement for the Masses

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.


Critical Analytical Workflow Component

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.

Late Bloomer Now a Driver

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.

Back End to GC, LC

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.

A Q&A with Select Mass Spectroscopy Experts

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.

How it Works

How Nanoparticle Tracking Analysis Works

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).
