plasma as a cross-sectional technology in many industry branches, but also in research laboratories, is an indispensable tool in surface treatment. plasma technology is used everywhere where quality, productivity, environmental sustainability, precision and flexibility is important.

the low pressure plasma system SurfActive One meets those expectations with its sophisticated technology and ideal man-machine interfaces. Applications can be found, for instance, in the following areas:

• polymer processing• electro and electronic Industry• Vehicle construction• packaging • Food Industry• medical technology, Biotechnology • pharmacy, cosmetics• Optics, Glass and ceramics • manufacturing of metal products• universities and Research Facilities

New chances in

surface technology

plasmas are ionized gases. plasma is the matter’s fourth state of aggregation after solid, liquid and gaseous phases. everyone knows plasma from the environment: for instance, lightning and polar lights. What is more unknown is the fact that plasma is the basis for many technical applications because of its unique characteristics. As a source of light, it lights flat screens or headlamps. Furthermore, fluorescent tubes or energy-saving bulbs are based on plasma. In surface technology plasma is irreplaceable. One uses its reactivity to specifically change surface properties and to manufacture materials with unique properties. plasma technology offers chances for new products, energy conservation and environmental protection. the possibilities are by far not exhausted.

Plasma – basis for many

technical applications

Surfaces made from a variety of materials will be cleaned gently and activated with the low pressure plasma system SurfActive One and its flexible operating range. the system is suited for usage in laboratories as well as in the industry.

the SurfActive One can complement and even replace wet chemical processes of surfaces’ prior treatment. there are no remnants and therefore no expenses for disposal. the simple and reliable treatment of thermosensitive materials is possible through plasma’s low temperature. plasma activation, for example, can increase synthetic’s wettability so that colors, lacquers and adhesives stick better.

the compact system’s special strength is its volume of 7 liters and its treatment of small parts with a dimension of 150 x 140 x 170 mm (width, height and depth) at a maximum. the intelligent construction enables homogenous plasma to provide a high quality of consistent cleaning and activation of surfaces. the SurfActive One is optionally also available with a rotary drum/table. Larger quantities of small parts can be positioned and treated on its rack. A special configuration ensures the plasma’s homogeneity as well.

Simple, reliable and flexible

the SurfActive One works with microwave plasma. Reliable standard components of German suppliers ensure a simple and, to a large extent, maintenance-free setup of the system and is therefore a reliable service in daily work routines. Furthermore, the microwave technique is highly efficient: energy absorption and gas consumption are low and water cooling is unnecessary. Ozone formation is also minimized.

the graphic interface with its process visualization adds up to the simple and secure handling of the SurfActive One. the programmable logic controller ensures a comfortable input of process parameter and guarantees repeatable treatment outcomes. different sets of parameters for automatic operations can be saved in one of the ten storage locations. In addition, manual operation is available at any time.

the SurfActive One satisfies with an optimized cost-benefit ratio. the system’s base model already includes a set of high quality equipment, including a mass flow controller to precisely control the gas flow for example. In the case that the base model does not meet one’s requirements anymore, the SurfActive One is easy to expand with the help of its modular design.

We offer our customers target- and benefit-oriented package solutions, helping them to keep their focus on their core business. these solutions range from application consulting, sampling to developing individual processes. In developing a perfectly fitting solution we use most recent and very efficient methods of surface analysis.

Plasma – basis for many technical applications

Plasmas are ionized gases. Plasma is considered to be the matter’s fourth state of aggregation after solid, li-quid and gaseous phases. Everyone knows plasma from the environment: for instance, lightning and polar lights. What is more unknown is the fact that plasma is the ba-sis for many technical applications because of its unique characteristics. As a source of light, it lights flat screens or headlamps. Furthermore fluorescent tubes or energy-saving bulbs are based on plasma. In surface technology plasma is irreplaceable. One uses its reactivity to spe-cifically change surface properties and to manufacture materials with unique properties.

neoplas tools – Surface Modifications

neoplas tools’ focus is on customer oriented solutions to treat surfaces with atmospheric pressure plasma systems. The company is an outsourcing of the Leibniz-Institute for Plasma Science and Technology (INP) in Greifswald. The ins-titute is Europe’s largest, non-university, research facility for low temperature plasmas, including its fundamental princip-les and technical applications.

kinpen – The portable plasma device

Surfaces are cleaned, activated and decontaminated at at-mospheric pressure with the handy kinpen. The device is particularly used for surface treatment of temperature-sen-sitive materials as, for instance, plastics. In addition, kinpen provides you an easy access to geometric challenging sur-faces such as narrow clefts, capillaries or subtlest bores. kinpen’s base model is argon-powered. The admixture of re-ducing or oxidizing gases can be done up to the percentage range. Furthermore, the device is convertible through the simple change of its electrode head to operate with molecu-lar gases like air or nitrogen.

Technology

For the monitoring of chemical compounds in gaseous media laser absorption spectroscopy (LAS) uses the property of molecules to absorb electromagnetic radiation of certain wavelengths. Therefore the laser light is sent through the medium which has to be analysed. By detecting the strength and position of absorptions the type and concentration of the present substances can be determined very fast (up to ns scale) with high precision (up to ppt level).

Quantum cascade lasers (QCL) are favourable radiation sources for LAS in the mid-infrared spectral range (3-20 μm) because they operate at room temperature and allow the design of compact robust instruments for industrial applications. The mid-infrared spectral range is of great advantage over the visible and near-infrared ranges, because many molecules have much stronger absorption and several chemical species absorb exclusively here. Therefore lowest substance concentrations up to ppt level can be detected.

High-Precision Gas Analysis in Real-Time

Measurable substances

Generally, with one laser it is possible to measure one selected chemical species. If however there are two interesting molecules, whose absorption lines are close to each other, both can be monitored with a single laser. The detection of higher numbers of chemical compounds is possible by using several lasers at different spectral positions simultaneously. Please note, that symmetric molecules as e.g. H2 or O2 are not detectable in the mid-infrared spectral range. In the table examples of some measurable species and their detection limits are shown.

Key benefits

� self-calibrating through continuous measurement of irradiated and transmitted laser light

� high selectivity by identifying distinct absorption lines of the chemical species

� very high detection sensitivity up to parts per trillion (ppt)

� rapid results with high time resolution up to the nanosecond (ns) range

� easy handling as lasers and detectors need no LN2 cooling

� no interference / distortion of the measured medium or the process to be monitored

� simultaneous measurement of several molecules by using multiple laser systems
