Provided is a developer for replenishment capable of forming a high-quality image even upon duration. The ink passage plate has first and a second surface, and is provided with a plurality of pressure producing chambers connected to the plurality of nozzles, and an ink reservoir communicating with the pressure producing chambers by means of ink inlet ports. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics andor cavitation physics allowing the desired fluid to penetrate and pass into and through the filter media. A kit useful for preparing pharmaceutical formulations of histamine releasers is also provided. The conductive layer is patterned to form a conductive line layer. The AC and DC responses are measured; a corrected DC response is determined using the AC response; and a concentration of the analyte is determined based upon the corrected DC response.
