DEA 288 Ionic

Comprehensive and Reliable

The measuring part of the software provides the user with a modern, user-friendly operating interface. Proteus now offers a quick and convenient input assistant for programming all relevant measurement parameters. Color-coded tabs facilitate data entry and guarantee that no important parameter is forgotten — whether it relates to information about the sample, the temperature/time program or the desired frequencies. Very helpful is the ability to post-program (for frequencies or duration) during a running measurement, as well as the option of online evaluation (SNAPSHOT). The well-proven Proteus software will ensure a comprehensive analysis.

The software offers these features, among others:

• DEA variables: ion viscosity, ion conductivity, loss factor, permittivity, tanδ as a function of time/temperature
• Multiple-window technique — clear presentation and evaluation of measurement data or graphical excerpts in multiple windows
• Multi-method plot — conjoint evaluation and presentation of, for example, DEA, DSC and DMA curves in a single graph for detailed material characterization
• Determination of characteristic values such as peak or extrapolated onset or endset, on a single curve or on a curve family
• Comparative analysis of up to 64 curves or segments from the same or different measurements
• Storage of the analysis results and status for later restoration and continuation with analysis
• Raw data preservation — original measurement data is always available
• Smoothing of the measuring curves with adjustable filter factors
• Data (ANSI, ASCII, csv) and graphic export (JPEG, BMP, EMF, PNG, TIFF)

Practical Set-Up for Sample Handling

One great advantage of DEA is the ability to use the same sample amount and geometry as is utilized in the real process. By applying the wide range of available sensors, almost any practical application can be reproduced:
 

• Spray coating of thin films
• Application by a drawdown bar
• Spreading of low- or medium viscosity materials
• Positioning of the sensor between the layers of a prepreg
• Dipping of the sensor in a liquid

Sensitive and Versatile Sensors for Any Application

In order to meet the requirements of a multitude of polymer processing applications, NETZSCH offers a great variety of dielectric sensors. These sensors can be classified as implantable or reusable. The latter type can be permanently mounted, for example, into a press, a mold or even into a sample holder for both DMA and rheometer.

Multi-functional Lab Furnace

With the easy-to-operate, collapsible lab furnace, it is possible to carry out heating, isothermal or cooling steps in the temperature range from -150°C to 400°C by using either two IDEX (or MS) sensors or a single TMS™ (or Monotrode) sensor.
Cooling can be realized via air compressor, Vortex tube (also air cooling), intracooler or liquid nitrogen (LN₂).
 

UV Lamp

The DEA 288 Ionic system supports the OmniCure S2000 UV lamp for studying light-induced reactions such as the UV curing of adhesives, inks or paints. The duration and intensity of the UV exposure are software-controlled (via NETZSCH Proteus). Multiple shots can be triggered during each segment.

Lab Press

Laboratory tests on Sheet Molding Compounds (SMCs), Bulk Molding Compounds (BMCs) and prepregs can be performed in an environment mimicking processing conditions by using a lab press, which is able to apply heat and pressure to the sample at the same time.

The sample itself is either situated directly between the platens (including DEA sensor) or - optionally - in a separate spring mold, equipped with a Monotrode or a TMS™ sensor. The temperature program of the press can be controlled via the NETZSCH Proteus software.
