DSC 214 Polyma


...a low-volume furnace and a high-tech sensor for significantly faster measurements and accurate results, saving your time by increasing your sample throughput. With that, imagine innovative shaped pans, developed to increase the reproducibility of your measurements.

The design of the Corona® sensor consists of a ring-shaped arrangement of the thermocouple materials chromel and constantan, which creates the thermal voltage in the ring, not in a point. This enables the Corona® sensor to detect even the slightest of temperature deviations between itself and the pan. It is thus the perfect complement to the Concavus® pan – which was specially designed with reproducibility in mind. With an Indium Response Ratio >100 mW/K, this pan-sensor combination delivers high resolution and high sensitivity in combination with increased reproducibility. This allows for the detection of weak effects and for the reliable separation of peaks occurring in close succession.

Innovative Shaped Pans

The slightly concave bottom geometry of the Concavus® pan always creates a precisely defined contact surface between the sample, pan bottom and sensor, significantly increasing the reproducibility of the measurement results. The patent-pending design of the Concavus® pan improves the reproducibility of any DSC measurement; it can be used not only in any NETZSCH DSC, but also in other heat-flux DSCs available on the market.

Aluminum pans for DSC analyses are usually purchased in bulk quantities and packaged loosely in a single, large compartment. Experience has shown that the quality of Al pans packaged in this manner may be impaired by deformations caused by interaction between the pans. NETZSCH has designed the 3in1 box, a sectioned container with 96 well organized high-quality Concavus® pans.

Integrated in the DSC 214 Polyma is an oval furnace (Arena®) with a very low thermal mass, which allows for heating and cooling rates of up to 500 K/min – values previously unachievable with heat-flux DSCs. The high thermal dynamic of the Arena® furnace enables two advantages over a conventional DSC.

Firstly, by choosing high heating and cooling rates the measurement time may be reduced significantly, increasing productivity.

Secondly, the highest cooling rates closely resemble real polymer processing conditions and enable simulation of isothermal crystallization behavior.
