INSIGHTS on Analytical Chromatography: Hydrogen, MS Detection, Modularity

by Angelo DePalma, PhD
“Fun new tools,” particularly in mass detection, have encouraged a new conversation among separation scientists, says Nicholas Hall, national sales director at LECO (St. Joseph, MI). “Every time this occurs, the instrument vendors engage in the equivalent of an arms race, where the battles are fought over specifications— more resolution, greater fragmentation capability.” But the real discussion has recently involved the very nature of chromatography, Hall says. “Just as important as the tool used for detection on the back end is the time and optimization that goes on at the front end.” Thus the resurgence of basic chromatography optimization, the application of solid analytical chemistry, and a focus on chromatography as the optimization of mass spectrometers. “If you have good separation and good sample preparation, and that goes into the MS, then you’re really optimizing the mass spectrometer’s capabilities.”

The Heart of the Matter

by Angelo DePalma, PhD
Capillary columns have changed the face of GC since their introduction about 35 years ago. The most obvious change involves resolving power: up to 50,000 theoretical plates on a 30-m capillary versus 1500 on a six-foot packed column.
