Abstract:
A test method and test apparatus is provided that employs a microfluidic device to characterize properties of a fluid. The microfluidic device has a first inlet port, an outlet port, and a microchannel as part of a fluid path between the first inlet port and the outlet port. While generating a flow of the fluid through the microchannel of the microfluidic device, fluid pressure at the first inlet port of the microfluidic device is measured and recorded in conjunction with varying the controlled temperature of the microchannel of the microfluidic device to characterize the properties of the fluid that flows through the microchannel of the microfluidic device. The properties of the fluid can relate to the clathrate hydrate formation condition of the fluid at the pressure of the flow through the microchannel of the microfluidic device.

The invention relates to a pressure sensor (100) for a measuring system (10) for measuring the concentration of gaseous and/or aerosol-like component of a gas mixture by using a reaction carrier (14) which has at least one flow channel (42), wherein the flow channel (42) forms a reaction chamber (46) having a reaction material (48) which is designed to enter into an optically detectable reaction with at least one component of the gas mixture that is to be measured or a reaction product of the component to be measured, and a measuring device (12), which comprises a gas connection sub-assembly (5) for the connection of a gas feed channel (16) and a gas discharge channel (18) to the flow channel (42) of the reaction carrier, and a gas conveying device (28) for conveying the gas mixture through the flow channel (42) of the reaction carrier (14). The pressure sensor (100) is designed to measure a pressure difference of a gas mixture flowing through the gas conveying sub-assembly (5) and/or flow channel (42) of the reaction carrier (14), and has an elastic element (102) which is designed to deform as a function of the pressure difference. The invention further relates to a measuring method, a measuring device and a reaction carrier for such a measuring system.

Abstract:
The present invention is related to a system and method for controlled manufacturing of mono-disperse microbubbles. According to the invention, the mono-disperse nature of the collection of generated microbubbles can be improved by releasing the pressurized gaseous medium used in the system using release valve units. This further allows the system to be embodied as a portable system. In turn, the operator of an ultrasound imaging apparatus may use the system according to the invention to generate microbubbles on a patient-by-patient basis.
