Patent attributes
A titration system is disclosed for determining content of an analyte in a sample. The titration system comprises: a controller; a reaction vessel; a titration vessel and an indicator vessel in fluid communication with the reaction vessel; a spectroscopy unit; a sensor for outputting a signal to the controller based on a force exerted by the reaction vessel on the sensor. The controller executes a stored program to: (i) perform titration by delivering to the reaction vessel a first mass of a first fluid comprising the sample, a second mass of a second fluid comprising indicator, and a third mass of a third fluid comprising titrant; (ii) detect color change in the mixture in the reaction vessel based on a signal from the spectroscopy unit and stop titration; and (iii) calculate content of the analyte in the sample based on the first mass, the second mass, and the third mass.
