The use of coaters on electron microscopy

The innovations in the field of science and technology led to so many discoveries and inventions. Among these innovations are the improvements when it comes to equipment used for scientific experimentation. The old tools that were used to understand scientific phenomena back in the days were no longer suitable for the far advanced research studies being made today. Among the improved versions of the scientific equipment would be the electron microscope. It is a very powerful version of the optical microscope that has high magnification. Typically speaking, an electron microscope can see things which were a thousand times smaller. It has been a very important tool especially when it comes to inspecting very small samples up close. While the electron microscope seems to be a very powerful tool for research, it is also a pretty complex machine which requires personnel training for people to be able to use it properly. Moreover, it is also a pretty delicate tool. In order to improve the imaging of a sample, it is required that the specimen is coated with a conductive layer, which are also known as coaters. They are essential sample preparation tools for any electron microscope users. Charging occurs in non-conductive materials such as glass, plastic, wood, organic samples, polymers and many others thus, without coating, surface charging occurs and deteriorates the quality of the electron microscope images. Coaters comes with a wide choice of conductive material for coating (targets), commonly using Gold, Platinum, Pt/Pd and carbon. Other coating material (targets) such as Chromium, Rodium, Copper and Aluminum are also available. Conductive coating is required in order to create sharper images of the sample when scanned under the electron microscope. This gives better view of the sample, thus providing clearer and better information for data gathering. The advanced technology helps us see the world more clearly, right down to the smallest particle.
