Precise dosing for fully automatic CMC measurements

(PresseBox) (Hamburg, ) .
- Presentation of KRÜSS' Micro Dispenser for fully automatic measurements of the CMC of surfactants at analytica 2014
- Accessory for the KRÜSS Force Tensiometer K100
- Creation of extensive concentration series for precise CMC measurement

At analytica 2014, KRÜSS GmbH will present the Micro Dispenser, a dosing unit for fully automatic measurements of the critical Micelle concentration (CMC). The Hamburgbased manufacturer of measuring instruments has developed the Micro Dispenser especially for the Force Tensiometer K100, which has taken up an established position in the market for some time now. Two combined Micro Dispenser units create the whole concentration series for the surfactant to be analyzed directly inside the measuring vessel of the tensiometer. The K100 measures the surface tension between the respective dosing steps fully automatic by using the ring, plate or rod method.

By software-controlled dosing and subsequent removing the added volume between measurements, a vast number of concentrations can be analyzed without being limited by the vessel size. Thus, a dilution by several orders of magnitude can be achieved in order to cover the concentration range of the CMC reliably.

Since the concentration steps can also be chosen very close to one another, the CMC can be determined based on a large number of measurements and thereby with high precision. The very accurate dosing volume of the Micro Dispenser minimizes the systematic measurement error even for very large concentration series. This also contributes to the precision of the system.
