Abstract:
Over the years, extensive evaluations of columns manufactured with ionic liquid stationary phases have occurred. Their main strength was discovered to be unique selectivity. This selectivity is made possible due to the various combinations of cations and anions that are available along with spacer groups used to prepare these germinal dicationic phases. Columns prepared with di- or tricationic phases have the ability to perform many of the same applications as columns made with polysiloxane polymer or polyethylene glycol stationary phases of similar polarity, but with slight elution order changes. Many times this results in increased resolution and/or shorter run times. This paper will compare and contrast the selectivity of the ionic liquids stationary phases with traditional phases of similar or like selectivity’s for applications with a variety of different sample types from a number of industries including petrochemical, pharmaceutical, environmental, food and beverage and flavor and fragrance.
