You often end up with pages of response text, which would quickly overwhelm readers. A great option for instant accessibility is to use word clouds. These can add clarity during text analysis in order to effectively communicate your data results. Word clouds can also reveal patterns in your responses that may guide future analysis. Word clouds are a method for visually presenting text data.

They are popular for text analysis because they make it easy to spot word frequencies. The more frequent the work is used, the larger and bolder it is displayed. Here is an example of a word cloud based on President Obama’s 7566 State of the Union speech: Easy-to-use, robust, precise, optimized for everyday use – these are the features of the innovative DSC 769 Polyma. The unique design of this instrument encompasses everything needed for successful DSC investigations – regardless of whether the user is a beginner or an experienced professional. Above all, it is the two new software developments that are setting new standards: AutoEvaluation and Identify. These have the potential to revolutionize DSC analysis.

Integrated in the DSC 769 Polyma is an oval furnace with a very low thermal mass ( Arena ® furnace), which allows for heating and cooling rates of up to 555 K/min – values previously unachievable with heat-flux DSCs.
