Dsc 60

Manufactured by Shimadzu
Sourced in Japan, Germany, United States

The DSC-60 is a Differential Scanning Calorimeter (DSC) manufactured by Shimadzu. It is a thermal analysis instrument that measures the difference in the amount of heat required to increase the temperature of a sample and a reference material as a function of temperature. The DSC-60 can be used to study a variety of thermal events, such as melting, crystallization, and glass transitions, in a wide range of materials.

Samples (3–7 mg) were accurately weighed using ENTRIS224-1S Balance, Sartorius Lab Instrument GmbH & Co. K.G. (Gottingen, Germany), into sealed aluminum pans with a capacity of 40 μL. The weighing pans were hermetically sealed with three vent holes. The samples were scanned at a heating rate of 10 °C/min under nitrogen purge from 25–400 °C [17 ] using Shimadzu DSC-60 (Kyoto, Japan) calorimeter. Shimadzu DSC-60 data analysis software was used for the analysis of thermodynamic events.

Melting points were measured in glass plates
on a Yanagimoto melting point apparatus. UV/vis/near-IR absorption
spectra in solution state and KBr pellets were obtained on a JASCO
V-650 spectrophotometer and a Shimadzu UV/vis/near-IR scanning spectrometer

recorded using an Ocean Optics HR4000 spectrometer. Differential scanning
calorimetry (DSC) was performed with a SHIMADZU DSC-60. TGA and differential
thermal analysis were measured using a SHIMADZU DTG-60. ESR spectra
were recorded with a JEOL JES-FE1XG. The magnetic susceptibility measurements
were performed using a Quantum Design SQUID magnetometer, MPMS-XL.
Single-crystal X-ray data were collected by a Rigaku XtaLAB P200 diffractometer
with graphite monochromated Mo Kα radiation (λ = 0.71075
Å). Powder XRD was performed on a Philips X’Pert Pro MPD
diffractometer using Cu Kα radiation (λ = 1.5418 Å).
Silver bis(trifluoromethanesulfonyl)imide, dehydrated dichloromethane,
and cyclohexane were commercially available and used without further
purification. N-n-Pentyl-10H-phenothiazine (1) and N-n-octyl-10H-phenothiazine (N-octyl analogue) were prepared according to the literature.19 (link) Compounds 1•+·BF4, 1•+·PF6, and 1•+·SbF6 were prepared
using corresponding silver salts by the similar method of 1•+·NTf2.

Lyophilized PEGylated nanoparticles were analyzed by means of the DSC method to ascertain the enthalpy changes that occurred because of changes in the physical and chemical properties of the samples. The Shimadzu DSC 60 (Japan) was utilized to carry out the DSC analysis on the PEGylated chitosan nanoparticles. In an un hermetically sealed aluminium pan, nanoparticle powder was placed, and the temperature was increased from 30 to 250 °C at a rate of 10 °C per minute while maintaining a 10 mL/min airflow min−1 (Madkhali et al., 2021 (link)).

DSC analysis of the samples was performed on a previously calibrated DSC 60 (Shimadzu, Tokyo, Japan) for temperature and heat flow precisely using Indium. SB, PCL/Pluronic F68, and SB loaded PCL/Pluronic F68 Nanoparticles DSC spectra were collected. Accurately weighted samples (3 mg) were put in hermetically sealed aluminium pans and heated at a scanning speed of 50 °C/min while purging with nitrogen at a rate of 10 mL/min through the melting temperature range. Endotherms were measured from 40 to 300°C against a reference of a sealed aluminium empty crucible.

Thermal Characterization of EPI Mixture

Check if the same lab product or an alternative is used in the 5 most similar protocols
The curing temperature of the EPI mixture was measured using a differential scanning calorimeter (DSC, DSC-60, Shimadzu, Kyoto, Japan). A total of 13 mg of the mixture was placed into an aluminum pan and heated to 30–300 °C (5 °C/min) in a nitrogen atmosphere at a feeding rate of 50 cc/min. In addition, the glass transition temperature (Tg) and curing degree of the postcured EPI was analyzed by placing a specimen of about 4.37 mg in an aluminum pan and heated to 30–300 °C (5 °C/min) in a nitrogen atmosphere at a feeding rate of 50 cc/min.
Thermogravimetric analysis (TGA, TGA-50, Shimadzu, Kyoto, Japan) can measure the initiating decomposition temperature, decomposition propagation behaviors, and total thermal stability in various atmospheres such as nitrogen, helium, and argon. The heat resistance of the EPI was measured by TGA. Thirteen milligrams of crushed blend samples (after curing) were placed into an alumina pan and heated to 900 °C (5 °C/min) in a nitrogen atmosphere at a feeding rate of 50 cc/min. The initial pyrolysis temperature (IDT), maximum weight loss temperature (Tmax), thermal stability index (A*·K*), and integral pyrolysis temperature (IPDT) were calculated based on the results of the TGA.

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.
