Sample Pan

Depending on the sample to be measured (especially if the sample is metal), it may melt the sample pan and damage the sample holder or other parts of the instrument. Before measurement, consider the compatibility of the sample with the sample pan and select the appropriate sample pan.

 ◆Aluminum sample pan

Used for general reactions, especially those involving the generation of gases such as decomposition reactions.

Leakage and deformation occur if the pressure inside the sample pan exceeds the pressure resistance (0.3MPa).  If dehydration, desolvation and other behavior (e.g. glass transition, melting) occur in the same temperature range, it may be possible to measure other overlapping behavior by reducing the heat absorption due to dehydration and desolvation. It allows for the measurement of gases generated by evaporation, sublimation, and decomposition without releasing them outside the sample pan.

◆Alumina sample pan

Used for general reactions in measurements above 500°C. 
Especially when measuring samples that react with Pt. 
The heat conductivity reduces the sensitivity of DSC (DTA) compared to Pt pans.

◆High-pressure sealable pan (SUS-SUS)

Sealing the sample pan enables measurement with reduced sample evaporation, sublimation and decomposition.
Leakage and deformation occur if the pressure inside the sample pan exceeds the pressure resistance (5 MPa).
Stainless steel reduces the sensitivity of DSC (DTA) due to low heat conductivity.

Sample pan shape

◇Open, crimp, seal

Pans are available in a number of shapes, including open, crimp, and sealed (hermetic) types. Since the DSC is used in most cases to measure the physical behavior of a sample, crimp pans are generally used in order to maintain efficient thermal conductivity between a sample and the thermal sensing plate. If the bottom of the pan is not smooth, a pseudo-peak may appear, or sensitivity may be reduced. Carefully check the condition of the bottom of the pan that comes into contact with the thermal sensing plate.

If the sample is a liquid or aqueous solution or when volatile components in the sample sublime or evaporate, you can use hermetic pans (sealed pans) to suppress sublimation or evaporation, making it possible to isolate heat endothermic reactions such as melting. Be sure to check the pressure resistance (maximum allowable pressure) of the pan to be used.

If pressure resistance is exceeded, sample and content leakage occurs. If the steam pressure or decomposition pressure of the sample is unknown, you can obtain the pressure resistance temperature for that sample using a sealed pan and the TG-DTA to check in advance the temperature at which the weight begins to drop.

Precautions regarding the selection of a sample pan

◇Precautions regarding the use of Al sample pans

• The melting point of aluminum (Al) is 660°C.
  Do not increase the temperature above 500°C when using an aluminum sample pan for measurement.
  Sample pans soften after being heated to high temperatures. Therefore, sample pans may deform if grabbed with tweezers or by the automatic sample changer. Be careful when handling sample pans after a measurement.
• Do not measure samples that react with aluminum. In some cases, the instrument may be damaged.
  Depending on the type of metal, the sample may form an alloy with aluminum and melt the aluminum.
  Samples containing acids and alkalis may react with aluminum.
• The zinc (Zn) calibration sample should not be reused as a calibration sample   as it may form an alloy with aluminum and the melting point may change.
