Simultaneous thermal analyzer-FTIR

Figures 8.2 and 8.3 show stacked curves obtained by TG-Fourier transform infrared spectroscopy (FTIR) of KL measured in air and nitrogen. TG-FTIR measurements were carried out using a Seiko TG 220 themogravimeter equipped with a JASCO FTIR7000 spectrometer [44,45,49,50]. Sample mass was 10 mg and heating rate was 200°C/min. Airflow rate was controlled at 100 mL/min. The gases evolved during the thermal degradation of KL were simultaneously analyzed by FTIR. Spectra were recorded at 30-second intervals each spectrum is the average of 10 one-second scans. The spectral resolution was 1 cm...

TG-FTIR was performed using a Seiko TG 220 instrument equipped with a JASCO FTIR 7000 spectrometer. TG measurements were carried out at a heating rate of 20 °C min. Nitrogen and air flow-rates were controlled at 100 ml min. The evolved gases during thermal degradation were simultaneously analyzed by FTIR. In order to obtain one spectrum, data of ten scans were accumulated at 1 s intervals. Each spectrum was recorded every 30 sec. The spectral resolution was 1 cm. ...
