Thermogravimetric Analysis (TGA) Services

Overview

Volt Carbon Technologies provides thermogravimetric analysis (TGA) services for customer-submitted samples, including graphite, battery materials, polymers, flame-retardant materials, minerals and other non-toxic powders. Testing is available under nitrogen and air atmospheres at temperatures up to 1100 °C.

Thermal Stability & DecompositionOnset, decomposition and DTG peak temperatures

Volatile Content & Mass-Loss TransitionsStep-by-step mass loss under nitrogen or air

Oxidation BehaviorAir-atmosphere testing, including carbon and graphite burn-off

Residual & Ash ContentInorganic residue remaining at the end of the test

TGA Data ReportingTG and DTG curves, mass-loss steps, residual mass and summary tables
