仪器简介：

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仪器是全球热分析技术的领导者，而差示扫描量热仪（DSC）则是TA的核心技术之一。在过去的5年中，我们始终致力于提高DSC的基本测试技术，如今，我们很自豪地为您介绍最新DSC研发成果——Q2000，Q200和Q20。
在位于美国Delaware州New Castle的TA仪器拥有国际标准化生产线，TA仪器能够满足任何应用需求或预算的限制，同时TA公司以完善的客户服务和支持回报客户，这些都是TA仪器公司的出众之处。

TA 仪器公司的最新Tzero™零技术，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DSC实验的速度和精确度。每一款全新的DSC测试系统都空前地提高了DSC的性能水平。

  • 橡胶中硫化检测方案(差示扫描量热)
    Two common problems in the TG-DTG analysis of unknown elastomer vulcanizates and probable solutions are discussed. The first problem concerns the difficulty in quantitatively determining the oil and elastomer in the compound in cases where their volatilization temperature range overlaps. After a review of the published works which studied this problem, isothermal TG (with or without vacuum) along with the use of "High Resolution" TG equipment is recommended. The second problem concerns separate determination of carbon residue from the elastomers and added carbon black in the compound, which very often oxidizes together. Subtraction of the carbon residue formed by the elastomers, determined by previous analyses, from the total weight loss in oxygen, was suggested in the literature. However, the quantity of char depends on type of the elastomer, as well as its concentration, curative type and amount and rate of heating. The problem is not, therefore, fully resolved. Experiments under slow feed of lean oxygen gas and isothermal temperature were also suggested in the literature. Under this condition, oxidation of carbon black and char may occur at slightly different temperatures and overlapping is minimized. However, this could be achieved only for large and medium particle size blacks (soft blacks) which oxidize at higher temperatures and not for the smaller particle size blacks, (used mostly in tire treads). Further work under slow feed of lean oxygen with a superimposed isothermal program and/or vacuum is recommended. The capability of the recently announced "High Resolution Thermogravimetric Analyzer" should also be explored.?

  • 材料中差示扫描量热检测方案(差示扫描量热)
    Since the introduction of the first commercial (temperature servo) device for quantitatively measuring heat flow into (or out of) a sample as it undergoes a transition, there has been considerable confusion about what name should be used to describe this analytical measurement (1). A wide variety of labels has been applied including Quantitative Differential Thermal Analysis (QDTA) (1,2,3), Dynamic Differential Calorimetry (DDC), Dynamic Enthalpic Analysis (DEA) and, of course, Differential Scanning Calorimetry (DSC). DSC has been the most accepted name largely because instrument manufacturers have used the term. With the introduction of other commercial devices, which also measure differential heat flow but are not based on the temperature servo approach , the confusion has increased. This confusion has been aggravated by the instrument manufacturers themselves who have often claimed unspecified advantages for their particular instrument. The manufacturer of the original commercial device, understandably, has attempted to limit the DSC definition exclusively to his design. He continues to claim that his instrument is the only “true DSC”.?

  • 材料中玻璃化转变检测方案(差示扫描量热)
    The purpose of this paper is to assist DSC users with interpretation of unusual or unexpected transitions in DSC results. The transitions discussed in the paper are several of the ones that most frequently create problems for the new user, and which can also fool even an experienced thermal analyst. By applying some of the recommended procedures and solutions, most laboratories will be able to improve the overall quality and interpretation of DSC results.
