APPLICATIONS: EDX Analysis


How to Make EDX Analysis Achievable on a K-kit Without tilting


By pointing the window long side to the detector and tilting the holder at some angles, which could make the EDX analysis achievable on a K-kit.


Give a tilt toward the EDX detector


EDX available angles for different kinds of TEM equipment


Some types of TEM installed with multiple EDX detectors usually can get a clear X-ray excited signal from K-kit, no need to turn any of body rotation or tilting.


Example


TEM: Hitachi 7700 EDX: Single Detector Liquid Sample: AuCl3 Tilt Angle: 0°, 10°, 20°


θ = 0˚ θ = 10˚ θ = 20˚ Au Signal
