A method for purifying a crude acetone raw material containing low molecular weight impurities using two columns is disclosed. A secondary processor, separate from a game controller on the gaming device, can be used to provide the enhanced functionality. In an embodiment, the negative capacitance circuit is connected in parallel with the differential outputs of the differential circuit. The customer inputs an item request into the keypad and it is sent to a predetermined or dynamically determined server pager for fulfillment. The method includes specifying for each indicator to be deployed, the domain or domains of the computer system in which each indicator should be deployed and deploying the specified configuration using a configuration deployment agent that creates, for each resource to be monitored, a configuration agent to handle the creation of the indicators. High resolution observation with small chromatic aberration factor Cs, Cc is made possible without forming a positive high voltage section inside an electron beam path of a lens barrel.
