料に基１をつけないよう平滑に仕上げである。For example, as shown in Fig. 1, a frame 2 having an appropriate thickness is placed on top of one flat plate mold 1, a rubber/plastic ivy material 3 to be molded is placed inside the frame, and then another layer is placed on top of the frame 2. One flat plate mold 1' is stacked on top of the other, and this is placed on the hot plates 4, 4 of the press.
' and then heated and compression molded at an appropriate temperature. If necessary, insert a separator between the flat mold and the sample. Flat plate molds are usually finished with a smooth finish so as not to leave any marks on the sample material.

有するため、赤外分光スペクトルを測定すると、第２図
に示す如く表面の間で透過の一部が反射することにより
光の干渉が生じ、凝似ピーク七して多数のピークがあら
れれる難点がある。Since the sample molded in this way has smooth parallel surfaces, when measuring the infrared spectra, light interference occurs due to a portion of the transmitted light being reflected between the surfaces, as shown in Figure 2. However, the problem is that there are many similar peaks.
このようなピークはスペクシルを解析するにあたって間
違った情報を与える事になるため、凝似ビークのあられ
れないフィルム作成方法がのぞまれていた。Since such peaks give incorrect information when analyzing speckles, a method for producing films that does not produce condensed peaks has been desired.

ることを特徴とする分光分析用試料作成方法に関する。The present invention has been made in view of these points, and when molding a rubber or plastic sample into a film for spectroscopic analysis, a flat material having minute irregularities on the surface is coated on one side of the sample. contact through a separator,
The present invention relates to a method for preparing a sample for spectroscopic analysis, characterized in that the sample is heated and pressed in that state to form it into a film.

A flat material 5 having an uneven surface, such as sandpaper, is placed on top of one of the flat molds 1, and a sample 3 is placed through a pallet 6. On top of that, the other flat mold 1' is placed. This is placed between the hot plates 4 and 4' of the press, and heated and compressed using the press.
こうして片面に微小な凹凸をもった試料を作ることが出
