Pyrolysis Characteristic of Tobacco Stem Studied by Py- GC/MS, TG-FTIR, and TG-MS
Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (PyGC/MS), thermogravimetric analyzer coupled with Fourier transform infrared spectrometry, and mass spectrometry (TG-FTIR and TG-MS) techniques. The composition of evolved volatiles from fast pyrolysis of tobacco stem was determined by Py-GC/MS analysis, and the e...
متن کاملApplication of TG - DTA to study of Ancient Potteries from Kaveripakkam , Vellore district , Tamilnadu , India
Firing temperature Ancient Potteries are among the oldest and most significant technological innovations in the history of human achievement, and were the first truly synthetic material. Spectroscopic techniques are very useful tools to achieve a detailed knowledge of the art works. In the present study thermogravimetry (TG) and differential thermal analysis was carried out for pottery samples ...
متن کاملبررسی روند کاهش وزن مواد منفجره PETN و پنتاستیت به روش های آنالیز حرارتی DTA/TG
In this research, the thermal stability and decomposition kinetics of pentaerythritol tetranitrate (PETN) and Pentastite explosives have been studied experimentally using non-isothermal differential thermal analysis (DTA) and thermo-gravimetric (TG) methods at heating rates of 4.0, 6.0, 8.0 and 10.0 °C/min. The kinetic parameter of activation energy (Ea) and critical ignition temperature fo...
متن کاملبررسی رفتار گرمایی لیزاردیتهای طبیعی در فشار اتمسفری، بر اساس تجزیه دستگاهی XRD و DTA-TG
Determination of stability limits, mineralogical changes and thermal reaction of serpentine minerals are very important for the investigation of magmatism, mechanism and depth of plates of subduction. During the subduction process, serpentine (Lizardite) minerals will release their water due to thermal reactions. This dehydration can play an important role in volcanism processes related to ...
متن کاملRapid Quantification of Medroxyprogesterone Acetate (MPA) in Human Plasma by LC-MS/MS
Background:Medroxyprogesterone acetate (MPA) is a common contraceptive agent taken both orally and as a subcutaneous or intramuscular injection. Current LC-MS/MSmethods for MPA quantification require large sample volumes and low-throughput analytical run times. Therefore, there are opportunities to improve upon existing methods for MPA quantification. Methods: MPA was extracted from 600 μL plas...
