7.2 Applying a Sample
The sample holder of the HTK 1200N consists of the
sample holder body, the sample carrier and a fixing
ring.
For faster work, the sample is prepared on the sam-
ple carrier and the sample carriers are simply ex-
changed.
Proceed, as follows:
1. Disconnect the cable for sample holder flange
from the sample holder.
2. Hold the sample holder flange and unscrew the
four fixing screws. Remove the sample holder
flange from the chamber and put it on the sup-
plied stand.
3. Apply a sample to an empty sample carrier, as
described in
and
4. Place the sample carrier (1) with the sample on
top of the sample holder body.
TIP: Make sure that the contact surfaces between
sample carrier and top of the sample holder body
are free of dust and sample residues to provide for
a good thermal contact!
5. Put the fixing ring (2) around the edge of the
sample carrier and carefully pull it downwards to
fix the sample carrier.
6. Insert the sample holder flange into the cham-
ber
.
7.2.1 Powder Samples
To apply the sample, use a spatula to press the
powder into the groove of the sample carrier and
subsequently smooth the powder's surface by
means of a glass platelet.
TIP: Make sure that the contact surfaces between
sample carrier and top of the sample holder body
are free of dust and sample residues to provide for
a good thermal contact!
CAUTION
Hot surface
Make sure that the sample holder is at room
temperature before touching it. We recommend
using a suitable meter for checking the tempera-
ture of the sample holder surface.
NOTICE
Risk of damage
When taking the sample holder flange out of the
chamber, immediately put it on the supplied
stand to avoid any damage.
NOTICE
Risk of damage
Before operating the
rotating
sample holder
beware of the shape of the thermocouple cable.
For safe operation do NOT tear at the cable and
preserve a minimum of four windings.
NOTICE
Risk of damage
The fixing ring is very fragile.
Please don‘t press or extend the fixing ring.
NOTICE
Risk of damage
Make sure that the materials of the HTK 1200N
are chemically resistant against the sample and
reaction products! Please refer to
