Soot content

Heating of the test sample at a stable rate, according to a controlled temperature change programme causes sample weight change through decomposition, oxidation reactions or emission of certain components. As a result, the method allows mass changes as a function temperature to be measured.
 

Equipment

  • The laboratory possesses a thermogravimetric analyzer:
    • TA Instruments model Q500 equipped with a quartz furnace for EGA analyses
    • device working temperature range from RT to 1000°C
    • controlled heating speed: from 0,1 to 100°C/min
