Method for analysis and device for carrying out the method

摘要

The invention relates to a method of analyzing liquid substances with the aid of a throughflow detector (10) and a reagent. A substance sample volume is introduced into a sample tube (20) through the medium of a supply tube (30) and the sample volume and a reagent volume are mixed together and caused to react with one another and then transported to the detector (10) for analysis purposes. The sample volume and reagent volume are introduced into the sample tube (20) through an orifice (70) in the supply tube (30), immediately after one another. The sample volume and reagent volume are intermixed in the supply tube (30), and possibly also in the sample tube (20), with the aid of an air segment which precedes the sample and reagent volumes. The invention also relates to apparatus for carrying out the method, and to a supply tube particularly designed for use with such apparatus.
