摘要： An auto-analytical machine for the analysis of liquid samples comprises, in combination, a reaction chamber, a sample reservoir for holding the sample to be analysed, connecting tubing having one end directed into the reaction chamber and the other end being arranged to be able to dip into a sample in the sample reservoir. A pressure controlled sample measuring device is adapted to move a predetermined quantity of sample into the connecting tubing, and a pressure control mechanism is arranged to move the predetermined quantity of sample into the reaction chamber. The measuring device and the control mechanism are adapted to move the sample by a change of fluid pressure in the connecting tubing. Reagents can be added to the reaction chamber in predetermined quantities, and a titration apparatus can supply a titration reagent at a slow rate until an end point is reached. A method of analysis of a liquid sample can be performed by using the above apparatus to draw a predetermined quantity of the sample into the reaction chamber by changes of fluid pressure so that an analytical reaction may be carried out in the reaction chamber upon the sample.
