Measuring surface free energy with only one click

Our innovative Mobile Surface Analyzer MSA measures surface free energy with two liquids, fully automatically, mobile and within one second.

The MSA supports you in your quality assurance in the pre-treatment and coating of solid materials in an ideal way. We will be presenting the precision instrument for the first time at analytica 2014.

The Mobile Surface Analyzer MSA measures the wettability of a sample based on the contact angle with two test liquids simultaneously and fully automated using our innovative "One-Click SFE" method. Reliable values for the two contact angles, the surface free energy of the sample and its polar part are available within one second. The result enables well-founded statements about wettability by aqueous or organic liquids, e.g. for coatings processes.

New, innovative dosing unit for parallel analysis with two test liquids

Simultaneous dosing and analysis of two drops obviates the need to change the test liquid during the material testing, as is the case with conventional dosing units. Our specially developed dosing system doses two parallel drops within milliseconds, with high volume precision and minimal kinetic energy. In spite its high speed the procedure resembles the gentle way of placing a drop with a dosing needle. The contactless method, without the usual dosing needles, prevents undesirable contact with the sample and possible damage or contamination of the sample.

Cartridges filled with the test liquids – usually water (polar) and diiodomethane (non-polar) – ensure that the dosing operation is easy to handle. Furthermore we have developed an alternative dosing solution for liquids which require extensive cleaning effort such as adhesives, inks or paints. The dosing system can be changed to an automatic syringe dosing unit within two minutes, which uses conventional disposable syringes.

Simple operation and flexible in use

Due to its use with a notebook and USB power connection, its low weight and small footprint the MSA is ideal for the mobile and non-destructive quality control. The instrument measures samples of any size, such as automobile bodies, and provides reliable values, even for vertical surfaces such as shower walls and for convex surfaces.

The modern, intuitive software automatically calculates the surface free energy based on proven and meaningful scientific models. For example, precise information relating to the polarity of the surface provides a reliable indication of the effect of activation by such methods as plasma treatment. Thanks to the simple measuring sequence and the software's clear user guidance, measurement errors due to incorrect operation are virtually ruled out.

At analytica 2014 fair in Munich, we will be presenting our Mobile Surface Analyzer MSA for the first time, and will be pleased to demonstrate how our newest instrument can assist you with quality control in the future. Visit us at Booth 311 in Hall A1.
