And a socket door is arranged at the inlet of the pipeline of the upper inserting plate and is in a normally closed state when an instrument is in standby.

3. Socket: and the sample chamber is fixed on the bottom plate of the sample chamber by screws. The inlet of the pipeline of the lower plug board is made into a bell mouth shape so as to correct the deviation of the direction which can happen when the plug board is inserted downwards. And the middle section of the lower inserting plate pipeline is provided with a reed for positioning the inserting plate, and the reed is fixed by a screw.

4. When in use, the wafer template carrying the sample is arranged in the inserting plate; opening the socket door, and inserting the plugboard from the socket; after the positioning groove of the plug board moves to the positioning point of the reed on the base, the positioning point blocks the positioning groove on the plug board, and at the moment, infrared spectrum measurement can be carried out on the sample on the wafer template corresponding to the positioning point.

5. The size of the upper inserting plate pipeline and the lower inserting plate pipeline can be just inserted into the inserting plate and can flexibly move in the inserting plate. The socket and the base are separated from each other, and the sample chamber top cover can be lifted and opened together with the socket, so that the operations of cleaning, maintaining and the like in the sample chamber are facilitated.

6. Except as specifically noted, the components are made of plastic or metal; all parts are black.

The utility model discloses the same with prior art is: the sample holder is used for placing the wafer template.

The utility model discloses the difference with prior art is: the sample frame comprises picture peg, socket and base, and the opening of sample room and external intercommunication is little, opens 3 samples of 3 sockets door survey during the use, so can reduce the disturbance of harmful gas to the internal environment of sample room, and can make things convenient for the operation that the sample put into, taken out, improves and detects work efficiency.
