Q600sdt ta instrument

Manufactured by TA Instruments
Sourced in United Kingdom

The Q600SDT is a Simultaneous Differential Scanning Calorimetry (SDT) instrument manufactured by TA Instruments. It is designed to perform thermal analysis by measuring the heat flow and weight changes of a sample as a function of temperature and time. The Q600SDT can be used to study a wide range of materials, including polymers, ceramics, and metals.

Thermal Stability and Li+ Transfer in SPE Membranes

A Q600
SDT TA instrument was used to analyze the thermal stability of different
SPE membranes under an argon atmosphere at a heating rate of 10 °C/min
from room temperature to 800 °C. A Nicolet IS50 spectrometer
was used to collect the FTIR spectra of SPE membranes. The activation
energy (Ea) was used to evaluate the Li+ transfer capability of SPE membranes, which involves Li+ dissociation and migration. A small Ea value implies a lower energy needed for Li+ transfer
through SPE membranes. Ea can be extracted
from the following equation: where σ, A, k, and T are the ionic conductivity,
pre-exponential factor, Boltzmann constant, and absolute temperature,
respectively.

TGA measurements (TA Instruments, New Castle, UK) were performed over a temperature range of 30–350 °C under a 50 mL·min−1 N2 flow, on a Q600 SDT TA instrument equipped with a DSC heat flow analyzer. Samples (5–10 mg of weight) were placed into the furnace inside alumina crucibles and heated with a ramp of 10°C·min−1. DSC curves were collected on a DSC Q200 TA Instrument (TA Instruments, New Castle, UK). Samples were accurately weighed (5–10 mg) and put into sealed aluminum pans. Calibration for temperature and heat flow was performed using high purity standards of n-decane, benzene and indium. All measurements were performed in a 30–350 °C temperature range, with heating rates of 10 °C·min−1.

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.
