原位系统大大增加了TEM的功能和实验可能性。使用特殊持有者，可以在TEM的真空室内加热或偏置样品。最近，使用带有电子透明窗口的真空兼容MEMS腔室，液体或气相实验已成为可能。
DENSsolutions was founded by a group of scientists who wanted better control over their in situ TEM experiments than what could be achieved with the available products. Together, they designed holders and MEMS nano-chips that provide more flexibility, better control, and minimal drift.
Nanoscience Instruments is the sole distributor for DENSsolutions products in the US. Our dedicated sales, applications, and service staff have over a century of combined EM experience.

什么是原位TEM?
常规TEM的局限性
常规TEM的主要是表征材料结构的成像工具。
在过去的几年中，最新的TEMS启用了原子分辨率成像和分析，这是通过使用图像或探针像差校正的TEM来实现的。事实证明，这些TEMS作为成像工具的性能对于识别各种材料结构非常有价值。
However, these conventional TEMs are still unable to support the whole research process. The reason is that conventional TEM is unable to replicate real-world environmental conditions (heating, gas, liquid, etc.) as the sample is always introduced into a static, high vacuum environment.
这从根本上限制了TEM的价值和可获得的好处。
的力量原位TEM
观察“现场”过程中的过程和在不断变化的外部刺激下观察过程是原位，时间解决的技术的首要目标。
DENSsolutions utilizes MEMS devices, called Nano-Chips, to control the sample’s environmental surroundings and replicate real-life application conditions inside your TEM. The introduction of in situ capabilities into a TEM transforms the system from a static imaging tool into a multi-functional laboratory.
With these in situ microscopy solutions, researchers are now able to characterize structures, measure properties, evaluate performance, and optimize processes & synthesis – all in one system!
