A simplified user interface for setting up measurement programs (SmartMode), automatic curve evaluation at the push of a button (AutoEvaluation), and a program for identifying unknown polymer curves (Identify) are the software’s keys to freeing up time for other tasks. Even inexperienced users are able to obtain fast, safe and meaningful results.DSC specialists can make use of ExpertMode at any time to access the full scope of Proteus® software functionality. Results generated by means of AutoEvaluation can be manually post-processed and newly calculated so that the experienced user maintains full control of the evaluation process. The Proteus® software version 7 – especially tailored to the DSC 214 Polyma – runs on Windows XP, Windows 7 or Windows 8.1. It is licensed with the instrument and can of course also be installed on other computer systems.
With the launch of the DSC 214 Polyma, the new SmartMode software interface was born.It features a clear structure, uniform navigation and user friendliness. Even less-experienced users will quickly find their way thanks to its intuitive interface. Under the Wizards menu item, a set of common pre-defined measurement methods can be found; these only require a few inputs and then lead directly to measurement at the touch of a button. They can also be combined with each other. Predefined Methods includes all of the materials on the NETZSCH “Thermal Properties of Polymers” poster with the corresponding methods to immediately start a measurement experiment. The User Methods menu item allows users to save methods which they have already carried out so that those measurement parameters are available as a template for subsequent measurements and do not have to be newly defined.
Calibration of the DSC instrument is a prerequisite for correct DSC measurements. It ensures that the instrument always measures within pre-defined parameters. The calibration process itself, however, should be simple, fast and – ideally – carried out right along with the process. The solution for this is AutoCalibration. This special software feature begins by offering pre-defined calibration methods for common standards, and then not only starts the calibration measurements but also – fully automatically – analyzes melting peaks, calculates calibration curves and even checks their validity. AutoCalibration thereby simplifies a routine task which can otherwise be very time-consuming.
AutoEvaluation is a completely novel software development allowing for the evaluation – automatically or at the push of a button – of unknown curves for thermoplastic polymers, rubbers and resins. AutoEvaluation analyzes DSC curves by first recognizing any key effects such as glass transitions or melting peaks, and then properly interpreting side effects such as recrystallization effects in logical steps. For the first time, users now have access to expert applications knowledge in the form of an intelligent software algorithm.
Identify is a unique tool for automatic identification and interpretation of curves with only a single click. This part of the software is designed for material identification and quality assurance. The analyzed properties of the DSC curve for a given material being investigated are compared with the integrated database, allowing for the automatic identification of plastic types. Such a database comparison is unique in the area of DSC technology. The Identify database contains a NETZSCH library for typical polymers and can also be extended by adding the user’s own polymers or mixtures. User-specific quality criteria can additionally be applied in order to define categories. For the first time, individual batches can be objectively compared with one another – an ability which is particularly relevant in the fields of quality assurance and failure analysis.
