It’s not often that someone can claim that going from a positive to a negative is a step forward, but that’s the case for a team of scientists from the National Institute of Standards and Technology (NIST) and private industry.

In a recent paper titled, “Expanding the Capabilities of Microfluidic Gradient Elution Moving Boundary Electrophoresis for Complex Samples,” by Elizabeth A. Strychalski, Alyssa C. Henry, and David Ross, published in the journal, Analytical Chemistry, the group significantly extended the reach of their novel microfluidic system for analyzing the chemical components of complex samples.
