Taking FFF to the Next Dimension
April 23, 2015
Way back in the mid-1960s, somewhere in the North American Midwest, J. Calvin Giddings spent a sleepless night in a noisy motel room. Even the room’s rattling air-conditioning unit gave him a hard time. Giving up on the idea of sleep, he turned his thoughts to the separation principle of field-flow fractionation (FFF).

The Rise, Fall and Rise of FFF
April 23, 2015
Nearly half a century ago, J. Calvin Giddings published a letter that laid out his ideas for a new separation strategy. It resulted in a collection of techniques known as field-flow fractionation (FFF). Here, three analytical scientists at the heart of FFF developments discuss the history, the ups and downs, and the relatively recent resurgence of the technique.
