Superior Performance in Surfactant Analysis

The DS800-TwoPhase membrane containing the immobilized surfactant-sensitive ionophores is highly durable and requires little maintenance. Reliable results are ensured over the whole lifetime since the sensor’s performance remains unaffected even after hundreds of titrations.

The DS800-TwoPhase is the sensor of choice for the potentiometric two-phase titration technique according to the standards DIN EN14480, 14668 and 14669. This technique provides the following advantages:

• Use of environment-friendly, non-poisonous solvents
• Short titration time and straightforward method parameters.

Undesired matrix effects induced by formulation compounds or by non-ionic surfactants are excluded by the two-phase titration technique indicated with the DS800-TwoPhase sensor. Large concentration ranges of anionic and cationic surfactants in formulations, raw products, liquid detergents and shampoos can be determined with excellent accuracy and precision.

The application power of the DS800-TwoPhase can be fully exploited with the Excellence titrators thanks to the intelligent method concept. The next simplifying step - automation - is easily taken thanks to the versatile Rondo sample changer. It allows titration of large sample series and includes full sample preparation.
