Abstract: In this tutorial, we discuss the motivations for doing two-dimensional liquid chromatography (2D-LC) and describe the commonly used implementations of the method. We review important guiding principles for method development, discuss the state of the art. In this lab, you will explore two applications of chromatography - identification of an unknown ink sample and the separation of food colorings. In paper chromatography, the sample mixture is applied to a piece of filter paper, the edge of the paper is immersed in a solvent, and the solvent moves up the paper by capillary action. PAPER CHROMATOGRAPHY This page is an introduction to paper chromatography - including two way chromatography. Carrying out paper chromatography Background Chromatography is used to separate mixtures of substances into their components. All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid.

The term “two dimensional liquid chromatography (2DLC)” refers to the technique in which two independent liquid phase separation systems are applied to the sample. 2DLC can be done by transferring either only the interesting portion of the first dimension effluent onto the second dimension, this is referred to as “heartcutting Cited by: In this lab, you will explore two applications of chromatography - identification of an unknown ink sample and the separation of food colorings.
