Is Thermogravimetry an efficient alternative to gas chromatography in degree of biodiesel conversion?
(2018-05-17)
This work aims to determine if thermogravimetry could be used to determine the degree of conversion of soybean oil to biodiesel without knowing the amount of ester in the sample, comparing the results with the values ...

Study of some volatile compounds evolved from the thermal decomposition of atenolol
(Springer, 2014-03-01)
Simultaneous thermogravimetry-differential scanning calorimetry (TG-DSC) and coupled thermogravimetry-infrared spectroscopy (TG-FTIR) analyses were used to study the antihypertensive drug atenolol. The TG-DSC curves provided ...
