RSC-400AS

技术特点

RSC-400AS是一種快速篩選量熱儀,具有:

  • 雙樣品測試,可在同時測試一個樣品和一個參比(惰性溶劑)時獲得更高的通量和更高的準確度
  • 輻射加熱和精確的溫度控制(0.01°C),可實現更準確的分解溫度測量
  • 使用8 mL樣品架,可以測試代表性樣品(體積和質量)
  • 可訪問的價格儀器和更換部件

特征

憑藉其較大的溫度範圍,RSC-400AS能夠測試從低到高分解溫度的各種材料,並測試高能分解,從而導致溫度升高。

其壓力範圍高達200 bar,是釋放大量氣體和測試大樣品的反應的理想選擇。

RSC-400AS是一種多功能量熱儀,可在各種模式下運行

溫度掃描模式可快速確定分解的起始溫度
雙掃描模式通過使用兩種加熱速率節省時間:快速加熱以達到起始溫度,然後降低加熱速率以進行分解溫度測量
等溫模式意在表徵反應動力學

应用案例

RSC-400AS is typically applied for testing thermal stability of chemicals when additional pressure and evolved gas data are of interest.

In the scale up process it is used after the quick screening stage on suspect materials identified using a DSC. Indeed, due to the central role of gas releasing reactions in plant process hazards, larger samples of about 5-10g are heated to destruction in RSC-400AS cells equipped with a pressure sensor. The focus of the study is to understand volume of gas evolved, when and how fast it’s evolved in order to understand its decomposition profile.
