  • Preparation of sample surface for SEM analysis (surface coating with carbon)

    The Carbon Coater is one of the most advanced sample coaters available for coating of non-conductive specimens prior to SEM X-ray analysis. Carbon is best used for EDS application.

  • Preparation of samples for scanning electron microscopy analysis

    Samples are cut to appropriate size, and then dehydrated with a critical point dryer. Afterwards they are placed on conductive platforms and, if necessary, coated with a nano-layer of conductive material (Au, Pt). These sample-baring platforms are then placed into a SEM specimen chamber.

  • Preparation of samples surface for SEM analysis (surface coating with a thin layer of a metal - Cr, Au, Pt/Pd - optionally)

    Sputter coating for SEM is a process of applying an ultra-thin coating of electrically-conducting metal onto a non-conducting or poorly conducting specimen. Coating of samples is required to enable or improve the imaging of samples. Creation of a conductive layer of metal on the sample inhibits charging, reduces thermal damage and improves the secondary electron signal required for topographic examination in the SEM. The coating technique that should be used depends on the required resolution and application. Chromium sputtered surface has very fine grain size which is most useful for FESEM imaging. Gold target is excellent and most widely used target material for standard SEM coating. But it should be noted that grain size is visible at high magnifications. Platinum/Paladium is also adequate for FESEM imaging. Its grain size is similar to Pt.

  • Preparation of semithin and thin sections for transmission electron microscopy analysis

    Ultramicrotomy is a method for cutting specimens into extremely thin slices, called ultra-thin sections, that can be studied and documented at different magnifications in a transmission electron microscope (TEM). It is used mostly for biological specimens, but sections of plastics and soft metals can also be prepared. Sections must be very thin because the 50 to 125 kV electrons of the standard electron microscope cannot pass through biological material much thicker than 150 nm. For best resolutions, sections should be from 30 to 60 nm. This is roughly the equivalent to splitting a 0.1 mm-thick human hair into 2,000 slices along its diameter, or cutting a single red blood cell into 100 slices. There are numerous pieces of equipment involved in the ultramicrotomy process. "Thin" sections, meaning sections from 50 to 100 nm thick, are able to be viewed in the TEM. Semithin or "thick" sections range from 0.5 to 2 µm, and are almost 10 to 20 times thicker than "thin" sections. These thick sections are also known as survey sections and are viewed in a light microscope to determine whether the right area of the specimen is in a position for thin sectioning. It is therefore a very common practice to view thick sections in a light microscope first, before proceeding with ultramicrotomy or thin sectioning. A small sample is taken from the specimen to be investigated. Specimens may be from biological matter, like animal or plant tissue, or from inorganic material such as rock, metal, magnetic tape, plastic, film, etc. The sample block is first trimmed to create a block face 1 mm by 1 mm in size. "Thick" sections (1 μm) are taken to be looked at on an optical microscope. An area is chosen to be sectioned for TEM and the block face is re-trimmed to a size no larger than 0.7 mm on a side. Block faces usually have a square, trapezoidal, rectangular, or triangular shape. Finally, thin sections are cut with a glass or diamond knife using an ultramicrotome and the sections are left floating on water that is held in a boat or trough. The sections are then retrieved from the water surface and mounted on a copper, nickel, gold, or other metal grid. Ideal section thickness for transmission electron microscopy with accelerating voltages between 50kV and 120kV is about 30–100 nm.
