Selecting Chromatography Paper on Amazon.com
Chromatography paper is made of cotton cellulose fibers and used in a chemistry lab for general chromatography, electrophoresis, blotting techniques, and sometimes as laboratory filter paper. It is typically packaged as sheets, circles, or rolls, and it comes in a variety of dimensions. Thicknesses of chromatography paper range from .17mm to 1.4mm. It has varying flow rates, usually stated as the distance in millimeters that water moves across the paper in the space of 30 minutes. In educational settings, a paper chromatography lab experiment will demonstrate how substances separate into components when deposited on a stationary phase (such as chromatography paper) and subjected to a mobile phase (such as a liquid solvent) that travels up the paper by capillary action. Manufacturers include Whatman.
