An arrangement of finely dispersed thin gold particles has an advantage over single crystal gold foil for tests of high resolution imaging capabilities in TEM. As with gold foil, image quality, magnification and instrumental stability are readily assessed, however, this gold particle specimen is superior for the determination of resolution capabilities since it offers a choice of crystalline orientations on static or low tilt stages. In addition, the thickness of the crystalline material is easily calculated from the projected shape of the gold crystal. The background noise arising from structure in the support film helps with determinations of the operating transfer function.
AGS132 requires refrigeration storage between 2-8˚C. To retain the integrity of the product, we will not ship on Fridays or where we cannot confirm a next day delivery. Additionally, we cannot accept customer returns for these products if ordered in error as the storage has been outside our control.
