Metrohm has introduced the 905 Titrando, which automatically determines pH and titratable acidity (TA) in soft drinks, juices and wines.
These analyses have traditionally been performed using a pH meter followed by manual titration with a glass burette; however this approach commonly causes several problems, including overshooting the titration's endpoint, variation of results between operators and transcription errors.
The Metrohm 905 Titrando eliminates these errors from pH and TA analyses.
This automatic titration system, which may be controlled via a PC and user-friendly Tiamo software or by a full-colour touch-control display, operates with the press of a button: the user simply places the sample on a stirrer stand, lowers the pH probe in, then presses the 'start' button, which results in completely automated pH reading and titration.
Additional analyses, such as sulfites (SO2), chloride (Cl) and vitamin C (ascorbic acid), can be added to the 905 Titrando.
Like all Titrando systems, the 905 can be expanded to include automatic degassing of sample, multi-sample automation and fully robotic sample preparation.
All Metrohm systems come with a three-year warranty and are fully backed by the company's Applications Laboratory support team.
