Evaluating the Role of antioxidants in the stabilization of hydroxypropyl cellulose by ATR-FTIR Spectroscopy
This study is aimed at evaluating the performance of tetrakismethylene-3-3,5-di-tert-butyl-4-hydroxyphenyl propionate methane S1010, tris2,4-di-tert-butylphenyl phosphite S1680 and ascorbic acid AA antioxidants in stabilization of hydroxypropyl cellulose HPC. For this purpose, a number of films with weight percent ratios of 0.4 w/w were prepared in a 1 isopropanol solution w/v. Then, the films ...
متن کاملChemical imaging of microfluidic flows using ATR-FTIR spectroscopy.
Elucidating the chemical composition of microfluidic flows is crucial in both understanding and optimising reactive processes within small-volume environments. Herein we report the implementation of a novel detection methodology based on Attenuated Total Reflection (ATR)-Fourier Transform Infra-Red (FTIR) spectroscopic imaging using an infrared focal plane array detector for microfluidic applic...
متن کاملRapid discrimination of maggots utilising ATR-FTIR spectroscopy.
Entomological evidence is used in forensic investigations to indicate time since death. The species and age of maggots or flies that are present at the scene can be used when estimating how much time has passed since death. Current methods that are used to identify species and developmental stage of larvae and fly samples are highly subjective, costly and often time consuming processes and requ...
متن کاملA new FTIR-ATR cell for drug diffusion studies.
The drug diffusion of most compounds, particularly hydrophilic molecules through the skin is limited by the permeation of the outermost cell layers of the epidermis, the stratum corneum(SC). For this reason it is of interest to characterize drug diffusion processes through this skin layer. A new FTIR-ATR cell was developed for non-invasive real time measurements of drug diffusion. The diffusion...
متن کاملAtr-ftir Spectrometry Characterisation of Polymeric Materials
The qualitative study on the efficiency of anti-caking and antioxidant additives as long-term thermal stabilizers for polypropylene (PP) using ATR-FTIR spectrometry is reported. Different kinds of additives are used in polymeric materials both for processing, for long-term stabilization and to prevent deterioration of the plastics performance. ATR-FTIR technique is one of the most important spe...
