sem sample preparation for nanoparticles

Sample preparation technique development for atom

Atom Probe Tomography (APT) can produce 3D chemical analysis on the atomic scale and there is an increasing interest for the analysis of nanoparticles (NPs) In the past there has been limited success with special geometry and non-bulk nanomaterials In this work several APT sample preparation techniques were trialed on zirconia NPs The main characterizations were performed using scanning

Sample Preparation for Scanning Electron Microscopy

Proper sample preparation plays an important role in obtaining the required information when using scanning electron microscopy (SEM) You need to consider the sample's size shape state and conductive properties prior to sample preparation Ideally the smallest representative sample size is the one to use The microscope's detection capacity is as much as 1m from the sample surface
