Viewing equipment matching the following properties:
The electrons interact with atoms in the sample, producing various signals (secondary electrons, backscattered electrons, X-rays), that can be detected and that contain information about the sample's surface topography and composition.
With a sample-retention system that enables direct measurements of 1 μL samples without dilution, and methods designed specifically for life scientists, NanoDrop Spectrophotometers have become indispensable in every laboratory.
