An automatic analyzer includes a status table storing the status of each analysis module and reagent information identifying each reagent, the supply of which is exhausted, and allowing tracking of the status of each analysis module, etc. A related method includes, in a firing chamber, separating whole ink into colloidal particles and ink vehicle such that the firing fluid within the chamber comprises primarily ink vehicle. A switch is operatively connected to the input terminal, and an offset sampling capacitor is operatively connected to the switch. The movable panel may be swept rearwardly while the side panels are pivotable to a high position and then after the side panels are lowered, the moveable panel is pivoted forwardly to sweep through the hopper and compact the swept articles into the opening of the storage body. Based upon the results of this determination, the processing unit either trips the electromechanical interface to interrupt power to a load, or inhibits tripping of the electromechanical interface, thereby reducing the occurrence of nuisance tripping. By such a method, – or -2-tetrahydrofuran amide is converted to – or -2-tetrahydrofuran nitrile through dehydration in the presence of a dehydrating agent and an amine base.
