Tg dsc

Manufactured by Netzsch
Sourced in Germany

The TG/DSC is a thermal analysis instrument that simultaneously measures a sample's weight changes (Thermogravimetry - TG) and heat flow (Differential Scanning Calorimetry - DSC) as a function of temperature or time under a controlled atmosphere. This instrument provides quantitative information about physical and chemical changes that a material undergoes during heating or cooling.

Oxidation Study of Yb-Lu-ZnSb

Check if the same lab product or an alternative is used in the 5 most similar protocols
Oxidation studies
of Yb14–xLuxZnSb11 (x = 0.3) were performed
on pieces of dense pellets using
thermogravimetry and differential scanning calorimetry (TG/DSC, Netzsch
STA 449 Jupiter) under a 50 mL/min flow of dry air (20% oxygen in
N2, Praxair) in Al2O3 crucibles from
room temperature to 1000 °C. To investigate the oxidation reaction
on a larger scale, a pellet of x = 0.3 was prepared
and after confirmation of purity by PXRD, the pellet was polished
and put in a box furnace in an Al2O3 holder.
It was heated at 200 °C/h to 1000 °C and held at that temperature
for 12 h in an ambient atmosphere. Half of this oxidized pellet was
set in epoxy for SEM imaging of the cross-section. The other half
was taken apart, the individual components were ground, and the PXRD
was collected and analyzed.

Maize Stalk Characterization Protocols

Check if the same lab product or an alternative is used in the 5 most similar protocols
Characterization of maize-stalk-loaded samples was done using a VERTEX 70 FTIR spectrometer (Bruker, Ettlingen, Germany) equipped with a diamond ATR accessory working at 4-cm−1 resolution with 128 scans, a scanning electron microscope Quanta FEG 250 (Fei, Eindhoven, The Netherlands) and a STA 409 PC Luxx simultaneous thermogravimeter-differential scanning calorimeter TG/DSC (Netzsch, Selb, Germany) for thermal analysis. FTIR spectra were acquired in quadruplicate, using atmosphere background, the best-quality spectrum, automatically ranked by OPUS software for consideration to be used in the analysis.

Comprehensive Characterization of Laminated AP Composite

Check if the same lab product or an alternative is used in the 5 most similar protocols
Field-emission scanning electron microscope (FESEM, Hitachi, Japan) was used to characterize the morphology, element mapping (EDS) and contents of the laminated AP composite. X-ray diffractometer (XRD, Bruker, Germany) was used to collect the XRD pattern of as-obtained samples. X-ray photoelectron spectra (XPS) were collected by an ESCALAB 250Xi photoelectron spectrometer (Thermo Fisher Scientific, USA). An BCA500 automatic oxygen bomb calorimeter was used to test the combustion heat value (IDEA SCIENCE, USA). The thermal decomposition properties of the samples were characterized by differential scanning calorimetry (TG-DSC, Netzsch, Germany) with the different heating rates (5, 10, 15, and 20 °C/min) in a Ar atmosphere over the temperature ranged from 25–600 °C.

Spectroscopic Characterization of AB 113 Dye

Check if the same lab product or an alternative is used in the 5 most similar protocols
The synthetic solutions of AB 113 used for adsorption, desorption and for biodegradation experiments were analyzed using a UV-Vis spectrometer from Hach Lange, Germany) in 1 cm quartz cells using the 200–800 nm. The spectra were recorded at 100 nm/min scanning speed for the ultrapure water in the adsorption experiment, acidic solutions for desorption experiment and dye-tampon buffer for biodegradation experiment. The pH buffer was measured with HI 255 Combined Meter (pH/mV & EC/TDS/NaCl) from Hanna Instruments, Nijverheidslaan, Belgium. The mass of IRA 402 and AB 113 powder was weighted with a XT220A analytical balance from Precisa Gravimetrics, Dietikon, Switzerland, with a precision of ±0.0004 g. For thermal analysis a STA 409 PC Luxx simultaneous thermogravimeter-differential scanning calorimeter TG/DSC from Netzsch, Selb, Germany was employed to verify AB 113 dye stability. FTIR spectra were acquired with a Vertex 70 spectrometer from Bruker, Ettlingen, Germany in transmittance mode in the 4000–400 cm−1 range with 4 cm−1 resolution and 32 scans.

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.
