A system and method are described for regulating water concentration in a dielectric fluid. The system can comprise electrodes capable of applying an electric field across the dielectric fluid, thereby causing charge carriers and water included in the charge carriers to move toward a respective electrode. The system further includes a trap positioned near the electrodes and comprising a water absorbing material capable of trapping water, thereby reducing the concentration of water in the dielectric fluid. It is also possible to measure properties of the dielectric fluid and use such measurements to control the water-trapping process.

A particle matter analysis device, an analysis method and a manufacturing method are disclosed. The particle matter analysis device includes a charger configured to receive power from a power supply device and to charge particles included in intaken air, an electrophoretic mobility particle collector configured to collect particles having electrophoretic mobility greater than a predetermined electrophoretic mobility among the charged particles based on an electrophoretic mobility and to measure a current of electrophoretic mobility particles, an aerodynamic particle collector configured to collect charged particles passing through the electrophoretic mobility particle collector based on an inertial force of the charged particles and to measure a current of aerodynamic particles, a filter configured to collect charged particles passing through the aerodynamic particle collector and to measure a current of filtered particles, and a processor, wherein the processor calculates a density of the particles based on a ratio of the current of electrophoretic mobility particles, the current of aerodynamic particles, and the current of filtered particles.

Various aspects of the present disclosure are directed toward methods and apparatuses for interacting a first liquid and a second liquid in one or more fluidic channels of a capillary structure. The methods and apparatuses can include providing at least one capillary barrier that positions a meniscus of the first liquid at a fluid-interface region using capillary forces within the capillary structure. Additionally, a path is provided along one of the channels for the second liquid to flow toward the fluid-interface region. Additionally, gas pressure is released, via a gas-outflow port, from the fluid-interface region while flow of the first liquid is arrested. Further, the first liquid and the second liquid contact in the fluid-interface region with the capillary barrier holding the first liquid at the fluid-interface region.
