1、 Product Introduction:
DSCA new comprehensive solution for measurement
Simple operation, powerful functionality, precise measurement, and convenient daily use - these are the excellent features of the innovative DSC 214 Polyma. This instrument is uniquely designed to meet the needs of both beginners and experienced professionals. Especially with the development of two new software: automatic analysis and curve recognition, which set new standards for DSC, these will trigger a revolution in DSC analysis.

Unique heat flow DSC with rapid cooling capability
The DSC 214 Polyma is equipped with an elliptical furnace body (Arena furnace body) with very low thermal mass, with a maximum heating/cooling rate of up to 500K/min. The thermal flow DSC has advanced reliability. Compared to the commonly used cooling rates of 10K or 20K/min, a temperature program that is closer to actual processing can be achieved.
Pioneering sensor technology
The Corona sensor with new patented technology has a chromium nickel alloy in the middle and a constantan alloy in the outer ring. Two materials are connected by diffusion welding. The Corona sensor has extremely high sensitivity and repeatability, coupled with the Concavus crucible of the new patented technology, achieving perfect reproducibility of the instrument.

III3 in 1 Box：
new typeConcavuscrucible
The newly designed crucible has added a special reinforcing ring at the bottom to ensure stable and good thermal contact between the crucible bottom and the DSC sensor bottom, significantly improving the repeatability of measurement results. The patented technology design of the Concavus crucible can improve the repeatability of all DSC measurements, making it suitable for NETZSCH and all hot flow DSC on the market.
new type3in1 Box
The 3-in1 Box is used in conjunction with the new Concavus crucible provided by Nike. Provide comprehensive protection during the transportation and storage of crucibles. Not only that, we also offer a fully functional archiving system, which is particularly suitable for applications that require long-term preservation of samples and regular retesting.

In the past, DSC crucibles and lids were loose in plastic boxes. There is static electricity between crucibles, which sticks together and sometimes makes it difficult to separate them. In addition, if the plastic box is accidentally covered, the crucible and lid may deform and cannot continue to be used.
The current crucible packaging makes sample preparation more efficient. The 3-in1 Box can accommodate 96 crucibles and lids, arranged neatly in an anti-static plastic box. This makes it easy to remove the crucible and lid. Each box is equipped with a sample label card for easy archiving of samples and measurement results. This compact 3-in1 Box is convenient for storing, transporting, and archiving crucibles and lids.

4、 Software functions:
Proteus ® sevenSoftware that saves time and effort
The simplified program settings user interface (SmartMode), one click automatic curve analysis (AutoEvaluation), and identification of unknown curves (Identify) are key features of the software that can greatly save time for other tasks. Even inexperienced users can quickly and safely obtain meaningful results.
After users have mastered DSC operation skills well, they can use Proteus in expert mode ® All functions of the software. The results obtained using AutoEvaluation can also be manually processed and recalculated, allowing experienced users to fully grasp the analysis process.
Proteus ® The 7.0 version of the software is specifically designed for DSC 214 Polyma and is compatible with Windows XP, Windows 7, or Windows 8.1. The software is compatible with the instrument and can be installed and used on another computer.
Intelligent mode（SmartMode）—The shortcut to efficiency
With the launch of DSC 214 Polyma, a new intelligent mode software interface has also been born.
Due to its intuitive interface with clear structure, consistent navigation, and user friendliness, even inexperienced users can quickly find ways to use it.
In the menu directory of Wizards, there are a series of conventional predefined testing methods. These methods require very little input to achieve one click testing. These methods can also be combined with each other. The predefined methods include the testing methods corresponding to all materials in the NETZSCH polymer property poster, which can start testing immediately. The customer setting method allows users to save their previous testing methods for use in the next test.
Automatic correction（AutoCalibration）—Simplification of necessary steps
Calibration of DSC instruments is a prerequisite for accurate DSC testing. This ensures that the instrument is tested within the preset parameters. But the calibration program itself should be simple and fast, ideally able to be completed in one go. The solution is automatic calibration. This special software feature provides pre-defined calibration methods for standard testing and fully automated analysis of calibration tests, such as analyzing melting peaks, calculating calibration curves, and checking their effectiveness. Therefore, automatic calibration simplifies time-consuming routine tasks.
Automatic analysis（AutoEvaluation）—Fully automated analysis method
AutoEvaluation is a newly developed software feature that can automatically analyze the curves of unknown materials such as thermoplastic polymers, rubber, and resins with just one click. The automatic analysis function first analyzes key effects such as glass transition and melting peaks on the DSC curve, and then analyzes other thermal effects such as recrystallization. Through the intelligent computing of software, users can obtain information that originally required professional knowledge.
Curve recognition（Identify）—Make every user an expert
Identify is a very special tool that can automatically identify and analyze curves with just a light tap. This part of the software is designed for material identification and quality control. Compared with the software integrated database, the curve characteristics of the given material can automatically identify the type of material. In the field of DSC technology, database comparison is rare. The database with recognition function not only includes the typical polymer curve spectrum library of NETZSCH, but also can be expanded by adding users' own polymer or composite curves. User defined quality standards can be used to set product categories. It is possible to objectively compare certain batches of samples with others.

Various cooling systems can cool the furnace body, whether it is through air compressors to room temperature or using liquid nitrogen systems to reduce the temperature to -170 ℃. Low cost mechanical refrigeration is another option besides liquid nitrogen, which can be used in the temperature range of -40 ℃ to 600 ℃ (IC40) or -70 ℃ to 600 ℃ (IC70).
NETZSCH offers crucibles of different materials (aluminum, copper, silver, high-pressure stainless steel, etc.) for almost all applications and materials. The replaceable pressure head press is suitable for cold welded aluminum crucibles and medium pressure stainless steel crucibles.
The automatic sampler (ASC) provided for daily applications, which can hold 20 samples, is also suitable for different crucible types.
Optimize sample preparation
Using NETZSCH's sample preparation kit, even small particles or small pieces of material reinforced with fiberglass can be quickly prepared.
The importance of selecting appropriate DSC, TGA, and STA crucibles for testing samples
The DSC crucible must be made of a material with high thermal conductivity, which ensures good thermal conductivity and low temperature gradient between the sample, crucible, and sensor.
The crucible must be made of inert material to ensure that the sample does not react with the crucible within the set temperature program. Unless the crucible is required to have a catalytic effect on the sample (such as using a copper crucible in the oxidation induction period test).
The crucible must not have any phase transition or other reactions in the set temperature program, and the melting point or softening temperature must be sufficiently higher than the maximum application temperature.
