Dsc 204 f1 device

Manufactured by Netzsch

Sourced in Germany

The DSC 204 F1 device is a differential scanning calorimeter (DSC) used for thermal analysis. It measures the heat flow associated with phase transitions and chemical reactions in materials as a function of temperature or time. The device provides precise and reliable data on the thermal properties of a wide range of materials, including polymers, metals, ceramics, and pharmaceuticals.

Thermal analysis was performed by differential scanning calorimeter (DSC) using a DSC 204 F1 device (Netzsch, Selb, Germany) under a nitrogen atmosphere. Samples of about 5.0–5.4 mg sealed in aluminum pans were heated from room temperature to 200 °C at rate of 10 °C/min. Indium with T_m = 156.6 °C was used as a calibrant. The crystallinity of PLA (χ_c) was estimated from the first heating cycle using the following Equation (1):
where ΔH_m is the enthalpy of melting during heating, ΔH_m* is the enthalpy assuming 100% crystalline PLA homopolymer 93.1 J/g [1 (link)].

Paramagnetic-to-Collinear Phase Transition

Check if the same lab product or an alternative is used in the 5 most similar protocols

The paramagnetic-to-collinear phase transition at T_collinear was also measured by differential scanning calorimetry (DSC) for REBaCuFeO₅ and YBa_1−xSr_xCuFeO₅ powder samples by using a NETZSCH DSC 204F1 device. Fine powders (mass, ~30 mg) were sealed into aluminum crucibles and heated up to 670 K with a rate of 15 K/min under Ar gas flow. The data were acquired during the heating process (see fig. S2).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
