Tga 60

Manufactured by Shimadzu
Sourced in Japan

The Shimadzu TGA-60 is a thermogravimetric analyzer that measures the change in weight of a sample as a function of temperature or time in a controlled atmosphere. It provides precise and reproducible measurements of weight changes in materials during heating, cooling, or isothermal conditions.

Thermal Analysis of IVS320 Compound

Check if the same lab product or an alternative is used in the 5 most similar protocols
TG and DTA curves for IVS320 were obtained on a SHIMADZU thermobalance, model TGA 60 (simultaneous TG/DTA), using an alumina pan (samples weighting 8 ± 0.1 mg) at a heating rate of 10 °C·min−1 in the 25–900 °C temperature range, under dynamic atmosphere of Air and N2 at 50 mL·min−1.
The TGA 60 equipment was calibrated using In, which was heated up to 200 °C followed by correction of the calibration temperature. Next, another experiment was run with the purpose of checking whether the melting temperature varied within ±0.5 °C.
In order to identify the thermal events presented as well as the temperatures (Tonset, and Tpeak) and energies (J·g−1) involved in these events, thermal curves were analyzed with the aid of the SHIMADZU software TASYS.

The TGA profiles were obtained in a thermobalance, model TGA-60 (Shimadzu). Samples were subjected to heating in the temperature range between 30 and 600 °C. Approximately 2 mg of sample were added in alumina crucibles, which were heated under a dynamic nitrogen atmosphere (50 mL min−1) and heating rate of 10 °C min−1. The thermobalance was calibrated using a CaC2O4.H2O standard in accordance with ASTM.

Comprehensive Material Characterization of Films

The film’s surface characteristics were studied by morphology observation through scanning electron microscopy (SEM) with a Jeol, JSM-6060 microscope. Energy-dispersive X-ray spectroscopy (EDX) was performed to determine the element’s concentration on the film’s surface under 10 kV incident electron energy. X-ray diffraction (XRD) was performed to evaluate the crystalline areas using a Bruker D8 Advance diffractometer under a voltage of 40 kV, current of 30 mA, and an incident angle of 2Ɵ (10 to 50°). The measurements of attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) were performed using a Prestige 21 model (Shimadzu) equipment, and the spectra were obtained under the spectral resolution of 4 cm−1. A calorimeter (Shimadzu, TGA-60, Kyoto, Japan) with a nitrogen flow rate of 50 mL/min was utilized to determine the thermal properties through differential scanning calorimetry (DSC). For DSC, samples were sealed in aluminum pans and submitted to the heating rate of 10 °C/min to be scanned from 30 to 200 °C.

Thermal Analysis of Chitosan-Aloe Vera Films

Check if the same lab product or an alternative is used in the 5 most similar protocols
Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were performed on chitosan films and aloe vera extract. TGA and DSC were done with a TGA-60 (Shimadzu, Kyoto, Japan) and DSC-60 (Shimadzu, Kyoto, Japan) analyzers, respectively. TGA analysis was performed with 5–10 mg samples in platinum pans in a dynamic nitrogen atmosphere (100 mL/min), in a range of 30 to 700 °C. The experiments were done at a scanning rate of 10 °C/min. For DSC analysis, samples (approx. 5–10 mg) were scanned in a sealed aluminum pan and heated to a temperature of 450 °C at 10 °C/min in a nitrogen atmosphere with a flow rate of 50 mL/min.

Characterization of Nanomaterial Composites

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fourier-transform infrared (FTIR) spectroscopy (Shimadzu FT-IR Affinity 1 S, Japan) was used to determine the functional groups of the obtained nanocomposites. The FTIR spectra were recorded in the range of 400–4000 cm−1 using the KBr disc technique. Morphological analysis of the composites was performed by scanning electron microscopy (SEM) (NanoSEM 650, detector: TLC). The X-ray diffraction (XRD) analyses were recorded using a Bruker D8 Advance diffractometer with Cu K α radiation and a 2θ scanning speed at 1.281°/min and in the range of 20°–80°. Transmission electron microscopy (TEM) was used to determine the average size and distribution of ZnO nanoparticles in the nanocomposites. The TEM images were recorded using a Hitachi HT7800 transmission microscope at a voltage of 100 kV. The thermogravimetric (TG) properties and thermogravimetric analysis (TGA) of the composites were determined by the TG-60 and TGA-60 (Shimadzu, Japan) instruments. The differential scanning calorimetry (DSC) and TGA measurements were made in aluminum containers using 6–8 mg of substance in a nitrogen atmosphere.

Differential scanning calorimetry (DSC) and termogravimetric analysis (TGA) studies were performed on zeolite-chitosan composite films. TGA was done with a TGA-60 (Shimadzu, Kyoto, Japan) analyzer. All analyses were performed with 10~15 mg samples in platinum pans in a dynamic nitrogen atmosphere (100 mL/min), between 30 °C and 700 °C (10 °C/min). DSC analysis was performed with a DSC-60 (Shimadzu, Kyoto, Japan) analyzer. Samples (approximately 2–3.5 mg) were scanned in a sealed aluminum pan and heated to 550 °C (10 °C/min) under the nitrogen atmosphere (50 mL/min). The weight loss (TGA) and the enthalpies (DSC) were calculated using the TA.60 software provided by Shimadzu.

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.
