Introduction to Ultra High Pressure Liquid Chromatography Whiteboard Video

submitted by: Chrom Solutions

This whiteboard video provides a brief history of chromatography, and explains the fundamental principles behind HPLC and UHPLC. It also describes the essential components, or modules, of a chromatography system, explaining how a sample travels through a liquid chromatograph.

Steviol molecular structure

submitted by: nsf
Responsible for the sweet tasting leaves of the Stevia plant, steviol glycosides have become popularized as a no-cal alternative to sugar. With funding from NSF’s Mathematical and Physical Sciences Directorate, R. Graham Cooks at Purdue University has applied his mass spectrometer to studying (among other things) stevia leaves. In an experiment that rapidly detected the glycosides in stevia leaves, Cook’s group has developed a powerful method for the rapid screening of plant materials...

Lactose molecular structure

submitted by: nsf
One of milk’s two sugars, lactose is not digestible in those lacking sufficient levels of lactase, which allows the body to metabolize that sugar. Certain parts of the world are reported to have higher incidences of lactose intolerance. NSFfunded Sarah Tishkoff at the University of Pennsylvania is studying the “gut microbiome” and its impact on nutritional status; such as its contribution to obesity, malnutrition and susceptibility to infectious disease. Her anthropologic study will...

Sucrose molecular structure

submitted by: nsf
Sucrose is table sugar—that ubiquitous sweet white crystal that sweetens our tea, coffee and apple pies, yet is also the villain blamed for tooth decay and other health issues. Through its Biological Sciences Directorate, NSF has funded Brian Ayre from the University of North Texas who studied the way sucrose produced in plant leaves through photosynthesis moved to and affected plant tissues. Sucrose is transported to tissues that are growing or accumulating storage reserves that can...

Glucose molecular structure

submitted by: nsf
Glucose, the simplest sugar, can be found in plants and is absorbed into bloodstreams during digestion. While most of us can be blissfully ignorant of our exact blood sugar levels after scarfing a Snickers, people who have diabetes or physicians with seriously injured patients need technology that provides accurate blood glucose data. Gymama Slaughter, an NSF-funded engineer at the University of Maryland Baltimore County, has created a new wireless, implantable sensor to monitor blood...
