FTIRphotoacousticvariable probe depthpolymer analysisFTIR Photoacoustic Spectroscopy (PAS) has advantages relative to conventional infrared techniques (transmission, reflection, and emission) because it is nondestructive, does not involve sample preparation, and can probe samples with compositional gradients and...
Solid State Analysis of Plant Polymers by FTIR 来自 Taylor & Francis 喜欢 0 阅读量: 36 作者:Abbott, Thomas P.,Palmer, Doris M.,Gordon, Sherald H.,Bagby, Marvin O.摘要: Wheat straw, kenaf, oak, and pine were extracted to give samples with various contents of lignin, hemicellulose, and...
Conclusions The composition an unknown polymer sample can be easily characterized by means of combined TGA/DSC-FTIR measurements. Table 1 summarizes the results obtained from the TGA measurement and the IR spectra for the particular sample investigated. The polymers in the unknown material were identif...
Fourier-transform infrared (FTIR) spectroscopyis the go-to technique for rapid identification of polymer compounds. In fact, the development of FTIR parallels the development of the plastics and polymers–from the chemistry lab to prototyping to production and shipment. Nicolet Summit FTIR Spectrometer ...
When selecting libraries, it is important to pick libraries based on mode of analysis and resolution. The libraries span applications for hazmat, forensics, food, polymers, organic and inorganic chemistry, and microplastics. Spect...
contamination may prevent or impede the chemical analysis of such items. If revealed to compromise archaeological remains, MP contamination could influence future excavation and sampling strategies, as well as impacting arguments for the long-term preservation of archaeological deposits. For buried archaeolo...
What is FTIR analysis used for? FTIR Analysis can be used to identify unknown materials, additives within polymers, surface contamination on a material, and more. The results of the tests can pinpoint a sample’s molecular composition and structure. How do you analyze FTIR results? The x-axis...

TGA-FTIR allows the polymer constituents of a sample to be analyzed. TGA analysis yields quantitative data relating to the composition of the elastomer whereas the IR spectra identify the decomposition products and through this the individual polymers involved. ...
Infrared spectroscopy combined with size exclusion chromatography has found wide acceptance in the study of deformulation of samples of unknown origin, compositional distribution in copolymers, impurity profiling in polymers, and branching in polyolefins. Use of this technique is enhanced by the availabilit...
