Karlo Natonton Experiment #4: Separation Using Chromatographic Techniques October 1, 2009 Part A: Paper Chromatography of Food Coloring Components Collect 15mL of deionized water, 15mL of 1-propanol, and 15mL of 1-butanol into a 50mL graduated cylinder. Pour into a 600mL beaker and cover the top with Saran wrap. Wrap Saran wrap with rubberband if necessary. Gently swirl the liquid and mix the components of the developing solvent. This is the development chamber. --- Obtain a 21.5cm x 11.5cm rectangle of chromatography paper. (Handle by the edges at all times.) Draw a line lengthwise 1.5cm from the edge using a pencil and ruler. Mark off ten points 2cm apart. Label with a letter. Write your initials in the upper left-hand corner.
