“…Chromatographic analysis, incorporating an eight-port valve, was used (20) for continuous monitoring of N2. The Derivatograph has had EGA incorporated into it (328), and equipment for simultaneous measurement of EGA and mass spectrometric analysis (444) has evolved so that DTA is incorporated as a simultaneous measurement technique (445). On application to a-KCH3SO4, EGA indicated (CH3)20 was evolved in small bursts, bubbles, and the mass spectrometry analysis confirmed this finding.…”
