An FTIR (Nicolet Magna 560) spectrometer [27] equipped with an attenuated total reflectance (ATR) probe was used to obtain the chemical composition of the polymeric material. Spectra can be obtained as either a pressed or cast film, or by attenuated total reflectance. The series encompasses a broad array of features and advantages, including a new and improved Universal Attenuated Total Reflectance (UATR) accessory, new fiber optic near infrared (NIR) probe, Go Button, and an enhanced version of PerkinElmer's Spectrum and AssureID(TM) software packages. |
