Being generation temperature of the ammonia due to differential thermal analysis system mass spectrometry and generation temperature

摘要

PROBLEM TO BE SOLVED: To provide a method for simultaneously evaluating the weight change of a test sample and the generation temperature and generation quantity of ammonia.;SOLUTION: A method for simultaneously evaluating both the generation temperature and generation quantity of ammonia employing differential thermal balance mass analysis is characterized by evaluating the generation temperature and the generation quantity of ammonia using an intensity profile calculated by a formula [I₁₇-I₁₈×0.212] from an intensity I₁₈ of a mass number 18 and an intensity I₁₇ of a mass number 17 determined using a mass analysis profile of the mass number 17 and a mass analysis profile of the mass number 18 of a measured test sample.;COPYRIGHT: (C)2012,JPO&INPIT
