Suspended Graphene on TEM Grids (Quantifoil Gold) – Pack 4 units
TEM 网格上的悬浮单层石墨烯（Quantifoil）——每包 4 件——在 1000 级洁净室中处理。单层石墨烯通过 CVD 生长并转移到 Quantifoil TEM 网格上。 石墨烯悬浮在 2μm 的孔上。 提供 TEM 上的悬浮单层石墨烯或 TEM 上的悬浮双层石墨烯。 以 4 个一包的形式出售。
选择哪种层类型（单层与双层）的提示——您的应用程序应指导您选择哪一种。 单层可用于表征或沉积其他分子并对其进行分析。 在双层中，被覆盖的网格孔更高（更高的产量）并且其机械阻力也更高。

Quality control
All samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene. All CVD materials are processed in Clean Room Class 1000. Each batch must pass the following tests:
- Raman Spectroscopy on each batch:
- I(G)/I(2D)<1
- I(D)/I(G)<0.1
- FWHM (G) < 23cm-1
-
FWHM (2D)< 44cm-1
-
Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity
If your application requires more specific controls (AFM, SEM…) please do not hesitate to contact us.
