Each method has its own benefits and draw-backs, which have already been discussed in detail by some reviewers.3,9 The more sophisticated methods, which require costly instruments like Infrared spectroscopy, Polarizing Microscopy and Thermogravimeter
have been reported to show overall accuracy of 80-85% in the estimation of renal stone composition.
Thermogravimetric analysis (TGA) was implemented by a thermogravimeter
(Q500, TA Instruments Co., USA) in the nitrogen atmosphere using a heating rate of 10[degrees]C/min from room temperature to 1000[degrees]C.
A TA Instruments Q500 thermogravimeter
(New Castle, DE) with an autosampler was used to measure the weight loss of the samples under a flowing nitrogen atmosphere.
Thermal stability was detected using a thermogravimeter
(TGA, TG 209 F3 Tarsus, Netzsch-Geratebau GmbH, Germany).
Thermogravimetric analyses (TGA) were performed on a TA Q500 thermogravimeter
. UV-vis absorption spectra were recorded using a PE UV-vis lambdazo spectrometer.
Thermogravimetric analysis (TGA) was performed on a Q500 thermogravimeter
(TA Instruments Company, USA) under nitrogen atmosphere at a heating rate of 10[degrees]C/min from 20 to 600[degrees]C.
This was identified via thermogravimetry, using a thermogravimeter
SDT-Q600, by considering that the water is more tightly bonded in C-S-H type products than in aluminosilicate type gels.
and Raman microscope were funded by EU, as part of the Operational Programme Development of Eastern Poland 2007-2013, Project no.
The as-received material was cut into small pieces (less than 20 mg) for testing by using a Netzsch-STA (TG-DSC) 449 F3 simultaneous thermogravimeter
. The heating rate employed was 10[degrees]C/min in a nitrogen atmosphere to prevent oxidation.
The oxidation degree of nanopowders was determined by the thermogravimeter
The polymer films were analyzed using a thermogravimeter
(TG 209F1, Netzsch) at a heating rate of 20[degrees]C/min within the range of 30-800[degrees]C under nitrogen atmosphere.
