THERMOFISHER SCIENTIFIC / FEI / PHILIPS Tecnai G2 T12

说明

A transmission electron microscope (TEM) with an operating voltage range of 20 to 120 kV. Capabilities include magnifications of thin samples (<200 nm) up to 700,000 times, an energy-dispersive X-ray spectroscopy (EDS) system, a Gatan MSC794 CCD camera for digital image acquisition, and a video camera for video-rate recording at moderate magnifications. The Tecnai T12 microscope combines all imaging, diffraction, and analytical techniques at good spatial resolution and detection efficiency. A variety of heating, cooling, and mechanical testing sample holders are available for use with this microscope. Application-Specific Modes Bright- and dark-field imaging. TEM microprobe and nanoprobe analysis. Small-probe convergent beam. Large specimen tilt. Accessories: Specimen Holders - Single-tilt, double-tilt, and tilt–rotate holders. Double-tilt cooling. Single- and double-tilt heating. Straining and indenting holders. Low-background single-tilt EDX holder. Energy Dispersive X-ray Spectrometer - An Oxford Inca system with an ultrathin window Si(Li) detector can detect characteristic X-rays generated by elements from beryllium to uranium. Software allows for the analysis of signals, digital background subtraction, and automatic peak identification.
