Folks from India extracted 99.6% pure eicosapentaenoic acid (EPA) using silver ion (argentation) column chromatography from hydrolyzed sardine oil. The individual fatty acids were determined as fatty acid methyl esters (FAME) by gas-liquid chromatography and gas chromatography-mass spectroscopy as FAME and N-acyl pyrrolidides.
Choosing the right column is key in Gas Chromatography. “Columns for Gas Chromatography: Performance and Selection” is a new hands-on reference for scientists and technicians working with packed column and capillary column gas chromatography. The authors Eugene F. Barry (University of Massachusetts Lowell) and Robert L. Grob (Villanova University) discuss the development, performance, selection, and […]
Cocaine is presently the most abused substance in Americas; however, the stimulant is gaining new advocates at an alarming rate in western Europe as well.
