Ta q500

Manufactured by TA Instruments

Sourced in United States

The TA Q500 is a thermogravimetric analyzer (TGA) that measures the change in the mass of a sample as a function of temperature or time in a controlled atmosphere. It provides quantitative measurement of physical and chemical changes that involve mass loss or gain due to decomposition, oxidation, or evaporation.

Thermogravimetric Analysis of CO2 Adsorption

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

Thermogravimetric sorption of CO₂ on zeolites, LDHs and composites was measured using a TGA analyzer (Q500 TA Instrument). All solids were first calcined in a muffle furnace at a temperature comprised between 400 and 600°C for 5 h, before transferring the samples to the TGA analyzer. To avoid any error, the test was done immediately after the first calcination. Finally, the samples were further calcined in situ for 1 h in N₂ prior to the measurement. CO₂ adsorption experiments were carried out at 1 atm with a constant flow of CO₂ (40 mL min⁻¹).

The zeta potential and particle size of the samples were measured by a Zeta-sizer instrument (3000HS, Malvern Ltd., UK). The elemental analyses were carried out by X-ray photoelectron spectroscopy (XPS, ESCALAB 250Xi). Extinction spectra were obtained using a Shimadzu UV 3600 spectrophotometer. The concentration of biogenic amines extracted from a raw fish (i.e., tuna) was determined by HPLC (Agilent 1260 series, Agilent Ltd.). The pH values of the solutions were measured by a pH meter (model: PHS-3E, Inesa scientific instrument Co., Ltd).

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.
