穆斯保尔谱测试( Mössbauer)
Janis多种产品可用于穆斯堡尔谱实验。这些产品已与ScienceEngineering and Education Co. (SEE Co.)穆斯堡尔光谱仪成功匹配使用,且获得理想的实验结果。即使使用闭循环制冷机系统,谱线展宽也可达到<1%。
闭循环制冷机系统采用特殊的振动隔离技术,无需外加固定装置即可与穆斯堡尔光谱仪匹配。 采用样品在交换气体中或蒸汽中的方式,可有效冷却粉末、液体或其他导热性差的样品   Janis用于穆斯堡尔谱测试的标准型千赢国际app手机下载安装包括:

Shown to the below are Fe57 Mössbauer spectra (dots) of a 25 micron iron metal foil at 298 K with the CCR off and on. The velocity scan of ± 2 mm/s covers only the innermost lines of the iron metal sextet. Also shown are least squares fits (lines) of a symmetric quadrupole pair with Lorentzian line shapes to each spectrum. The results of the fits were linewidth estimates of 0.234 mm/s with the CCR off and 0.241 mm/s with the CCR on. The uncertainty in the line width estimates due to the counting statistics is ± 0.002 mm/s. NOTE: Data provided by Science Engineering & Education Co.
