THMSG600 Sample Preparation
When working with fluid inclusions both the
optical performance and the temperature perfor-
mance becomes critical. It is very important to
avoid using too many glass cover slips as each
layer affects the sharpness of the image seen by
the microscope.
For accurate results it is most important that the
surface of the block, window and carrier are ex-
tremely clean, since air gaps between the silver
block and the sample window will result in tem-
perature errors.
The block is made of silver and since it is a soft
metal it can get scratched easily especially by
using sharp fine tweezers. This can cause a ridge
to form which prevents the sample window from
sitting flat on the block with the resulting air gap
causing significant temperature errors.
For this reason we recommend that the sample
and windows are always handled using the
Linkam Vacuum Tweezers.
G7T Sample Holder with Silver Lid
The G7T (1) has a tapered internal edge (2) to
enable the straight edge of the 7mm sapphire or
quartz window to locate correctly inside the hold-
er.
To load the sample holder open the side door of
the stage and slide the G7T in. Push the sample
holder as far as it will go then gently push the
door shut and lock the door in place with the
thumb screw.
