Abstract: Disclosed is a liquid sending method using a sample processing chip having a flow path into which a plurality of liquids flow, and the method includes: sending, into the flow path, a first liquid held in a liquid holding portion provided in the sample processing chip by applying pressure to the liquid holding portion; sending, into the flow path, a second liquid in a storage portion provided in a liquid sending device connected to the sample processing chip, through an injection hole provided in the sample processing chip, by applying pressure to the storage portion; and forming, in the flow path, a fluid containing the first liquid having been sent from the liquid holding portion, and the second liquid having been sent through the injection hole.
Abstract: The invention relates to the use of nondendrimeric, high-functionality hyperbranched polyesters and polycarbonates which are obtainable by reacting (i) at least one aliphatic, cycloaliphatic, araliphatic or aromatic dicarboxylic acid (A2) or derivatives thereof, or organic carbonates (A2?) with (ii) at least one x-hydric aliphatic, cycloaliphatic, araliphatic or aromatic alcohol (Cx) which has more than two OH groups, where x is a number greater than 2, preferably from 3 to 8, more preferably from 3 to 6, even more preferably from 3 to 4 and especially 3, and (iii) at least one fatty acid amide alkoxylate (D) of saturated or unsaturated C2-C30 fatty acid amides with an average of from 1 to 40 alkylene oxide units as demulsifiers for splitting crude oil emulsions.
