Applicant's summary and conclusion
- Executive summary:
Test system
Capillary tube in a metal block
Stuart SMP30.
Preparation
The samples of the three batches are put into capillary tubes fused at one end. To obtain a uniformly packed sample, the capillary tubes are dropped from a height onto a watch glass.
Measurement
The three capillary tubes, filled with the samples, are placed in a heated metal block. The temperature is raised up to 60°C and once it is reached, it is stabilized for 120 s. Then the metal block is heated so that the temperature rise is 5°C/min.
