Determination of step:
Open switch, stable 20min.
First set the starting temperature than the melting point of the low 10 , heating rate 2 / min.
The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample was compressed into about 1cm high .
When the actual temperature reaches the set temperature and stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.
