The Dutch Society for Thermal Analysis has developed tests to measure the resolution and the sensitivity of Differential Scanning
Calorimeters. For this test the substance 4,4′-azoxyanisole is used. This substance shows two transitions: a solid to liquid
crystal transition at about 117°C (ΔH≈120 J g−1) and a liquid crystal to isotropic liquid transition at about 134°C (ΔH≈2 J g−1). The resolution test is performed using an amount of 5 mg substance and a high heating rate of 20°C min−1. The resolution is evaluated by measuring how well the two peaks are separated. An amount of 0.25 mg substance and a low
heating rate of 0.1 °C min−1 is used for the sensitivity test. The sensitivity is evaluated as the ratio of the peak height of the LC-transition and the
top-top noise level.
Members of the TAWN were asked to participate in the test. Each participant was provided with an amount of sample and a test
procedure. 47 Contributions were received and these results are presented.
