Comprehensive Two-dimensional Liquid Chromatography (LC X LC)
Maarit Kivilompolo, Jaroslav Pól and Tuulia Hyötyläinen
Comprehensive two-dimensional liquid chromatography (LC X LC) is a new and expanding technology that provides enhanced separation power by combining two LC modes with different separation mechanisms. This review describes the principles of this technique and guidelines for designing successful methods. Examples from food, plant, polymer and bioanalytical sectors are discussed.
