Environmental Control

฀gilent’s industry-leading environmental isolation chamber (EIC) has been speciically designed to meet the many requirements of intricate, demanding atomic force microscopy and scanning probe microscopy research. The EIC mounts directly to the 5500 and provides a sealed sample compartment that is completely isolated from the rest of the system. Eight inlet/outlet ports permit the low of many different gases into or out of the sample area.

฀gilent scanners reside outside the EIC, so they are protected from contamination, harsh gases, solvents, caustic liquids, and other damaging experimental conditions. With the EIC, humidity levels can be controlled, oxygen levels monitored and controlled, and reactive gases easily introduced into and purged from the sample chamber.
