They e n guarantee that the sensor is not contaminated by the measurement. The type of crucible e used for a measurement can have a large effect on the quality of the results obtained, and G in addition, also influences important characteristics of the DSC measuring cell. Consider- ing the relevant factors before the measurement can often help to save time later on when interpreting the curve. Features and benefits: n Large volume – increases the sensitivity n Low mass – pushes the resolution to the limit n Purity – no interaction of the sample with the crucible n Material – guarantees high thermal conductivity and form stability n Flatness – ensures perfect thermal contact and no artifacts The following points are particularly important for DSC and SDTA measurements: Crucible volume Temperature Crucible mass range Crucible
