Energy-dispersive x-ray detector

The activity of chemically active AF paints usually relies on the reactivity of organometallic compounds (e.g. TBT-, Zn-, Si, Cu- acrylates and Zn-resinates) and inorganic pigments (i.e. CU2O). In spite of this, scanning electron microscopy coupled with energy dispersive X-ray detectors (SEM-EDX) has not been used extensively to characterise such reactions. Bishop and Silva... 

The presence of soluble Ca salts in the sediments of Unit C was particularly obvious in our observations using an energy-dispersive X-ray detector with the SEM to compare the intensities of characteristic X-rays. The results in Table IV were obtained for the bulk samples. The loss of Ca from Unit C sediments (probably as CaC03) upon washing with dilute HCl is... 

Le Mont Scientific B-10 system features an energy-dispersive x-ray detector. Particles are loaded and interrogated to find size and shape various software options are available. The Bausch and Lomb system has also been applied to electron beam microscopy [l87,l88].rracor Northern describe an integrated system for the collection and processing of analytical and image data from SEM and STEM [l89,l90].Various sample preparation methods have been described. 

IGC at elevated temperatures is a serious problem in the sulfidation of nickel alloys. Deep penetration can occur rapidly through the thickness of the alloy. This type of IGC can be evaluated by (i) X-ray mapping during examination by a scanning electron microscope equipped with an energy-dispersive X-ray detector and transmission electron microscopy (4). 

Figure 21.2. Left Typical SEM setup with secondary electron (SE), rmg-shaped backscattering (ESB = energy selective backscattering), and EDX (energy dispersive X-ray) detector right depth from which SE, BSE, and X-rays are typically emitted when exposing the sample to a primary electron beam with an energy of up to 30 keV...
