15469 TEM Grid Holder on Pin This TEM grid holder holds up to 4 TEM grids. It enables imaging and analyzing specimens on TEM grids in the SEM. For EDS applications it is beneficial to place thin films on a TEM grid or small particles on a TEM grid with a support film. This can significantly reduce background in the EDS spectrum and increase detection limits of the EDS detector. Hole size in the top and base is ø2.1mm. Opening angle on the holes in the top and base is 120° to reduce electron scattering and improve X-ray collection. Overall diameter is 18mm (0.7"), standard 3.2mm (1/8") pin with a 15mm (0.6") long pin. The longer pin allows for a larger distance from the SEM stage pin holder and therefore greatly reduces electron and X-ray scattering contribution for the SEM stage. TEM grid locations are numbered. Material: vacuum grade aluminum with brass screw. Screw used is 2-56 x 3/16, Flat, Brass 15470 (use 15463-20) TEM 4 Grid Holder for SEM This low profile TEM grid holder holds up to 4 TEM grids. Thin copper spring clips hold the grids in place, providing a wider viewing angle suitable for both imaging and spectroscopy of samples on grids in SEM. It is often beneficial for films or small particle samples to be placed on a TEM grid with a support film. This can significantly decrease the background in an EDS spectrum, and improve the detection limit. The holder has a short 6mm pin. It is 25.3mm (0.996") in diameter with an overall height, not including the pin, of approximately 3.8mm (0.15").
