Abstract: The analytical process utilized in the system of this invention comprises three (3) step distinct steps wherein an analyte of interest in a test sample is initially labeled and subsequently isolated within a porous medium of a test device. Once isolated within the medium, the label is displaced from the analyte, or from the complex with the analyte, and converted, under electrolytic condition, to a metallic species which is caused test to deposit upon a working electrode of the test device. This working electrode is part of an electrode array that is positioned coincident with the porous medium, yet maintained physically remote therefrom. This deposit is then stripped from the working electrode, under anodic stripping conditions, and the current generated within the electrode array monitored. The characteristic response curve that is produced thereby can be correlated with the identity and concentration of the analyte(s) with the test sample.

Abstract: Carbon monoxide in reformate gas is removed by oxidizing reactions in a plurality of catalytic components (4A-4C) disposed in series. Air from air supply valves (6A-6C) is supplied to the catalytic components (4A-4C). The oxidation amount of carbon monoxide in the catalytic components (4A-4C) depends on air supply flow rates of the air supply valves (6A-6C). A controller (7) controls the air supply valves (6A-6C) so that the ratio of the air supply flow rate to an upstream component (4A) with respect to the air supply flow rate to a downstream component (4C) decreases as a flow rate of reformate gas decreases. In this manner, reverse shift reactions generating carbon monoxide as a result of reactions between carbon dioxide and hydrogen contained in the reformate gas can be suppressed in the downstream catalytic component (4C) when the flow rate of reformate gas is low.

Abstract: The drop-by-drop evaporation of a liquid or solution is controlled by monitoring the disappearance of each successive droplet and by actuating the deposition of the next droplet until the desired volume is deposited. In the case of a solution, non-volatile residue (NVR) is collected on a deposition surface plate as a relatively small mound.

The environment is preferably controlled so that inadvertent contamination is precluded from interfering, and thus the method permits the automatic, micro-processor controlled evaporation of liquids with the resultant deposition of non-volatile residues from solutions within relatively short periods of time.
