Ionic Liquids Improve Separations
Two years ago, room-temperature ionic liquids became the first new type of commercial stationary phase to hit gas chromatography in more than three decades. Scientists have known about ionic liquids for more than a century, but their usefulness for GC wasn’t proven until 2005.

In a Pittcon symposium, separation scientists described the . . .
