The prior art uses formvar as the final reinforcing film of the film, but this film has a weak film strength, and is particularly liable to be deformed by electron beam irradiation. There was a problem that a process such as vapor deposition had to be added. In addition, cellophane tape is used as a reinforcement when separating the oxide film from the base, but the waiting time for peeling the cellophane tape in the subsequent process is not constant and it may take a long time (one day or more). There were some problems. Further, the conventional technique has a complicated process, so that there is a large individual difference such that only some of the skilled persons can succeed.

As the mesh used in the present invention, any mesh can be used as long as it is a mesh conventionally used in an electron microscope. The above is the method of preparing the coating film sample for analysis according to the present invention. The film sample prepared by the present invention is preferably used in an instrumental analyzer such as a transmission electron microscope (TEM) and Auger electron spectroscopy, and is particularly suitable as an observation sample for TEM.

The reason why it is preferably used for Auger electron spectroscopic analysis is that peeling the film from the plated metal improves the Auger electron analysis sensitivity of the film. The reason why it is preferably used as an observation sample for TEM is that a single film is desirable for observing with a high-magnification, high-resolution image because the film structure is dense. The plating to which the present invention is applied includes Zn plating, Sn plating,
There are Cu plating, alloy plating containing these metals, and the like, but the point is that any plating made of a metal that forms mercury and amalgam can be applied.

In the present invention, the film thickness is 0.01 μm to 1 μm.
It is preferably applied to the film of m. If it is less than 0.01 μm, the film is broken, and if it exceeds 1 μm, electrons are not transmitted, which is not preferable. In the present invention, instead of applying collodion and formvar on the oxide film of the conventional method,
It is a method of vaporizing carbon and reinforcing it with paraffin only while peeling the oxide film, chromate film, etc. from the base metal plate such as steel plate, so not only the process is simplified but also the first vapor deposition. Since the formed carbon remains as a reinforcing material for the coating until the end of the process, it is possible to collect a coating sample of good quality without breaking the coating from a wide range of samples.

First, carbon vapor deposition performed at the beginning of the sample preparation step may be carried out in the same manner as in the general replica preparation for TEM, but the carbon film as the sample for TEM is different in film quality from the case where formvar is used as the reinforcing film. Is durable,
In particular, since the stability of the reinforcing film due to electron beam irradiation during TEM observation is high, it is not necessary to add the reinforcing film at the final stage.

In the next step, cellophane tape is conventionally used as a reinforcement when the oxide film is separated from the base material by mercury amalgam, but the present invention is different in that paraffin is used. The sample coated with paraffin is strong enough to grasp the end of the sample piece with tweezers, and cellophane tape may be completely omitted. Further, the advantage of using paraffin as the reinforcing film is not particularly limited to the type of solvent for dissolving the reinforcing film in the subsequent step, and alcohol, ether or a mixture thereof may be used, and the temperature of the solvent may be changed to paraffin The temperature may be raised to 45 ° C. or higher, which is higher than the melting temperature of

Further, according to the present invention, although the cause has not been clarified, the time for floating the sample on the mercury and separating the film from the base material is shortened as compared with the conventional method which may require one day or more. Separation became possible in about 1 hour.

A method for preparing a sample for observing a coating formed on a plated metal plate with a transmission electron microscope, wherein carbon is vapor-deposited on the surface of the coating and paraffin is applied onto the carbon, and then the plated metal plate is coated. Separate the plated metal plate and the film by floating it on mercury and forming the underlying plated metal and amalgam, then immerse the separated film in an organic solvent, heat it to dissolve the paraffin, and then fix it to the mesh. A method for preparing a coating sample for a transmission electron microscope, which is characterized by:
