Dry solid samples

In the case of dry solid samples, the sample is mounted on a circular flat plate drilled with one or several central holes (A), the plate is then screwed on the ring (B), which is then inserted in the sample stage (C). The sample is preferably mounted on the front side of the plate, but if needed, it can also be mounted on the back side, provided it fits in the 22 mm diameter.

The sample can be glued on the holder or clamped between 2 plates. The sample holder hole can also be covered with thin Ultralene film (SPEX-CERTIPREP) to maintain the sample without glue.

Keep in mind that only part of the holder is accesible with the motors and only a partial section of the holder is accesible in transmission.

                                                             

                         Areas accesible to the stage motors (in red) and accesible for transmission measurments (in blue).       

Large samples can also be  sealed between two ultralene (SPEX-CERTIPREP) films, using a "clip" sample holder.
