Although the IR detectors are not as popular as the MS, pyrolysis-gas chromatography / Fourier transform IR (Py-GC/FTIR) occasionally has been used in polymer analysis. [Pg.188]

Infrared (IR) techniques are reported in literature to be used in combination with different thermal experiments as a convenient tool of analysis. For example, IR-EGA (infrared evolved gas analysis) was used for obtaining information on different thermal and combustion processes [19]. A simple IR attachment where the sample can be pyrolyzed close to the IR beam is also commercially available (Pyroscan/IR from CDS Analytical). Although the IR detectors are by far not as popular as the MS, pyrolysis-gas chromatography/Fourier transform IR (Py-GC/FTIR) occasionally has been used in polymer analysis. Such applications have been commonly related to the analysis of certain gases such as CO2, CO, CH4, NH3, etc., where the MS analysis is less successful [20, 21]. [Pg.141]

Analytical investigations may be undertaken to identify the presence of an ABS polymer, characterize the polymer, or identify nonpolymeric ingredients. Fourier transform infrared (ftir) spectroscopy is the method of choice to identify the presence of an ABS polymer and determine the acrylonitrile—butadiene—styrene ratio of the composite polymer (89,90). Confirmation of the presence of mbber domains is achieved by electron microscopy. Comparison with available physical property data serves to increase confidence in the identification or indicate the presence of unexpected stmctural features. Identification of ABS via pyrolysis gas chromatography (91) and dsc ((92) has also been reported. [Pg.204]
