A technician checks the column bed volume on a column that is supposed to be 2ml. If the bed volume is not 2ml, is this a problem? Why or why not? The column drips very slowly. Suggest a method to increase the rate of flow through the column. How can you check to ensure that this method does not compromise the separation? A scientist would like to know the charge of a certain protein at pH 7.2. How could this column be used to help determine the overall charge of the protein at pH 7.2? What problems might occur using the proposed approach, and how might they be addressed?
