Abstract: A device for capillary chromatography comprising at least one first receiving space arranged in a circuit board and of a form such that the first receiving space is suitable for at least partially receiving a coiled part of a capillary separation column. Also a method for manufacturing such a device. Using such a device and method the greatest possible advantage can be gained from both miniaturized and integrated gas chromatographs (minimal dead volumes; integration options; small thermal masses and rapid temperature regulation; low cost price; small dimensions, weight and energy consumption; portable and flexible in use) and from the use of a usual capillary separation column (very good separation; high precision and reproducibility). The capillary separation column can herein be heated uniformly, rapidly and accurately.

Abstract: A method for building a device having fluidic and electrical functions includes the steps of: mounting a building part with fluidic and electrical functions on a substrate that is provided with a fluidic circuit; fluidically connecting the building part with the substrate; electrically connecting the building part with the substrate; and mechanically connecting the building part with the substrate. Flip-chip technology is utilized and a seal is made by of a gasket. With such a method, a hybrid microfluidic system can be built in which materials and processes for realizing the various connections (fluidic and mechanical and electrical) can be selected in principle independently of each other so the individual processes can be optimized independently of each other in a large measure. With the application of flip-chip technology, great accuracy in the positioning of the building parts can be achieved.

The electrical connection is made by means of a current material and a well-developed process.

Abstract: An air filter of which the dimensions may be easily adapted to the shape and dimensions of air ducts, especially air ducts of air condition equipments, comprises a number of frame shaped modules (1) made of plastics material. To each module a filter bag (2) is welded. The side faces (1a, b, c, d) of each module are provided with a system of ribs (5) or embossments (6). For joining modules substantially airtightly together a system of ribs or embossments on a side face of a module is connected to a complementary shaped system of ribs or embossments on the side face of another module by sliding movement or snap action. Preference is given to an embodiment whereby inclined side boundaries of interengaging complementary systems form a dovetail connection.
