Thermo Orion Model 925 Flash Titrator(TM)



World's Most Advanced Acid Base Titrator

BEVERLY, Mass. (September 10, 2002) - Thermo Orion, a Thermo Electron business (NYSE:TMO) and leader in the development and manufacturing of chemical measurement product lines, introduces the new Flash Titrator, the worlds most advanced acid base titrator enabling titrations in less than 30 seconds.

The Thermo Orion Model 925 Flash Titrator utilizes a new nanotechnology for very rapid Acid/Base titrations with no external titrant. This revolutionary system employs a 12 mm probe which features independent pH FET, planar conductivity and
temperature sensors, plus a platinum electrode surrounded by the pH sensor that electrochemically generates the acid or base titrant from the sample itself. The generated acid or base titrant moves by diffusion over the pH FET's sensing area and the pH inflection vs. the time profile is obtained. This diffusion time is proportional to the concentration of the acid or base in solution and is reported in the concentration unit selected by the user. Results correlate to traditional titration methods.

The Model 925 titrator features microprocessor design, which automates calibration and measurement procedures for a wide variety of applications. Twelve acid and base titration templates are coded into the meter, and 30 actual sample methods that have been developed at Thermo Orion are also included to make set up of new methods simple. These methods may be edited and saved to a new method number to reduce keystrokes and get you titrating samples in a flash! Titration data can be sent to your PC for documentation.

The Flash Titrator also features direct pH and Conductivity measurement for aqueous samples. The Model 925 Flash probe, is an active, electronic device where the potential developed at the sensing surface is dependent on solution pH or conductivity. This surface potential induces a measuring transistor to determine the pH or other parameters of other solution. Temperature is simultaneously monitored at the precise point of measurement, minimizing temperature error.

Thermo Orion offers an automated Flash Titrator system that incorporates the Thermo Orion AS3050 Autosampler for efficient, unattended operation. Comparisons between traditional acid base titrations and the Flash titrations show very good correlation of the concentrations with great Relative Standard Deviations (RSDs) between the Flash runs.
