DSC:
Differential Scanning Calorimeters (DSC) measures temperatures and heat flows associated with thermal transitions in a material. Common usage includes investigation, selection, comparison and end-use performance evaluation of materials in research, quality control and production applications. Properties measured by TA Instruments’ DSC  techniques include glass transitions, "cold" crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability.
差示扫描量热仪 (DSC)
DSC测量的是与材料内部热转变相关的温度、热流的关系，应用范围非常广，特别是材料的研发、性能检测与质量控制。材料的特性，如玻璃化转变温度、冷结晶、相转变、熔融、结晶、产品稳定性、固化/交联、氧化诱导期等，都是DSC的研究领域。TA仪器公司的最新Tzero技术，是DSC发展历程中的一项革新性技术，大大提高了基线的稳定性、测量的灵敏度和解析度。Tzero技术可以直接测量热容Cp，并且能大大提高调制MDSC实验的速度和精确度。Q系列DSC产品Q1000，Q100，Q10的性能都因此获得了大幅度的提高。

TGA:
Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. Thermogravimetric Analysis instruments are routinely used in all phases of research, quality control and production operations. TA Instruments offers the Q5000, Q500, Q50, and simultaneous DSC / TGA (Q600) to meet the various needs of the researcher, quality control analyst and academic instructor.
热重分析仪器(TGA)
TGA测量的是材料在一定环境条件下，其重量随温度或时间的变化，目的是研究材料的热稳定性和组份。TGA在研发和质量控制方面都是比较常用的检测手段，TA仪器公司提供高性能的Q系列热重分析仪，包括Q5000IR，Q5000SA，Q500，Q50，和DSC/TGA同步分析仪Q600，来满足研究、开发和质量控制领域日益增高的要求。

SDT:
The Q600 provides a true simultaneous measurement of weight change (TGA) and heat flow (DSC) on the same sample from ambient to 1,500 ºC. It features a proven horizontal dual beam design with automatic beam growth compensation, and the ability to analyze two TGA samples simultaneously. DSC heat flow data is dynamically normalized using the instantaneous sample weight at any given temperature.
DSC/TGA 同步分析仪
SDT Q600是可以同时测量样品的热流、转变温度和重量变化三种信息，同时便于实验结果的诠释、提高实验室效率，并确保样品实验条件的同一性。Q600非常适合高温材料(金属、矿物质、陶瓷和玻璃)的研究，设计上采用了水平式双天平测量原理，标准配置有自动气体切换和数字式气体流量控制器以及触摸屏控制，工作温度从室温至1500℃。Q600也可连接红外分析仪FTIR和质谱仪MS，进行气体分析，使得分析工作更加准确。

DMA:
Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. The Q800 DMA instrument incorporates unique technology to provide the ultimate in performance, versatility, and ease-of-use. State-of-the-art non-contact, linear drive motor technology in our DMA instruments provide precise stress control. Ultra sensitive optical encoder Dynamic Mechanical Analysistechnology is used to measure strain and air bearing technology insures virtually friction-free movement. The combination of these technologies sets the Q800 Dynamic Mechanical Analysisapart from competitive instruments that use conventional stepper motors, LVDT strain measurement devices, and mechanical springs. The Q800 Dynamic Mechanical AnalysisDMA instrument operates over a wide temperature range (-150 to 600°C) and provides multiple modes of deformation including dual/single cantilever and 3-point bending, tension, compression, and shear. The clamps are individually calibrated for data accuracy and the elegant but simple design facilitates sample mounting.Dynamic Mechanical Analysis
