Structural Characterization of FAP and FGA Polymers

Check if the same lab product or an alternative is used in the 5 most similar protocols
The structures of FAP and FGA polymers were identified with FTIR spectrophotometer (Frontier IR, PerkinElmer Inc., USA). The polymers and potassium bromide were mixed uniformly and pressed into a thin sheet with tableting machine (FW-4A, Tuopu instrument Co., Ltd, China) under 22 MPa. The spectra were scanned from 400 cm−1 to 4000 cm−1. Additionally, the structures were further identified by 1H-NMR (Bruker, Karlsruhe, Germany) at 600 MHz with deuterated chloroform as the solvent.

DRIFT Spectroscopy of Lignin Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
DRIFT spectroscopy was performed on a PerkinElmer Frontier IR instrument. Lignin samples were prepared by mixing lignin (0.015 g) and potassium bromide (0.5 g) in a mortar until a homogeneous solid powder was obtained. Spectra were collected at room temperature from 500 to 4000 cm−1 with a scan number of 32. The background was recorded using solid KBr finely ground in a mortar.

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.
