Digital titrator |
| abstract |
A digital titrator for use in chemical analysis instruments comprises a vertical transparent tube (buret) (1) containing the titrant and monitored by an image reader (CiS) (2) parallel to the tube. A reservoir of titrant solution (3) communicates with the buret, the titrant being transferred by the action of a pump (4). The titrant solution is released into the reaction flask (6) through a valve (5) and a sensor (7) in the flask collects and transmits information about the progress of the monitored reaction to the computer (8). The analysis data are stored, processed and displayed to the user on a screen and/or printed. A flexible tube interconnects the upper ends of the tube and of the reservoir and transfers the saturated inner atmosphere from one to the other, according to the pressure variation caused by the movement of the meniscus, without any gas exchange with the atmosphere, preventing solvent evaporation and the concomitant alteration in titrant concentration. For the same purpose, air entering the reservoir from the atmosphere goes through a saturation flask (9) containing pure solvent. A PCI (10) is used to control the computer-assisted operations and an agitator (11) homogenises the titrated substance. |
