Title:The Chromatography Process of Expo Markers Abstract:This experiment is to uncover whether or not the Expo Markers are homogeneous or heterogeneous mixtures. The experiment will conduct filter paper being slightly submerged in a container of water and inspected for pigmentation changes. In the experiment the pigments will rise up the filter paper once exposed to the water (solvent). After the experiment‚ it concludes that the mixture is a homogeneous mixture due to the chemical

values obtained from the paper chromatography technique. The hypothesis of the experiment was that all of the five listed pigments would be present in the extracted plant leaf according to the Rf values. PROCEDURE/APPARATUS: The equipments used were a 18 x 150 mm test tube with stopper‚ graduated cylinders‚ Erlenmeyer flask‚ mortar and pestle‚ metric ruler‚ tall jar‚ acetone‚ tiny test tube‚ small brown bottle‚ petroleum ether‚ plant leaf‚ dried parsley flakes‚ water‚ glass petri dish‚ stapler‚ sand

Chromatography – Analyzing Analgesics by TLC and Isolation of β-Carotene by Column Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used
