5.4 Performing Melting Point Measurement
1. Place a small amount of sample in a capillary
tube and insert into the aluminium sample
block. Up to three tubes can be
accommodated at any one time.
Note:- Only full length capillary tubes (100mm)
should be used with the SMP30. If capillary
tubes smaller than 60mm in length are used for
melt determinations it may be extremely
difficult to retrieve them from the sample
block.
2. Adjust the angle of viewing for maximum
comfort.
3. Set up the instrument with the required
plateau temperature and ramp rate using the
procedure described in "New
Measurement Set-Up".
4. Use the lower menu key next to "START" to
instruct the instrument to heat/cool to the
plateau temperature. The display changes to
indicate that the instrument is "Heating/
Cooling to plateau" and gives an estimated
time for the instrument to reach the plateau
temperature.
4.1 Once the instrument reaches the plateau
temperature the display changes to
"STABILISING AT PLATEAU 120". The timer
will then countdown from 120 to 0.
4.2 Once the countdown reaches 0 the
instrument will make an audible bleep and
the display will change to:
09:00
