biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed‚ a technique that uses a negatively charged ion exchange resin with an affinity for molecules with

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled
