Thermogravimetric Analysis (TGA) Simulator

Thermogravimetric analysis tracks a sample's mass while it is heated at a steady rate, and each drop in the curve is a real chemical or physical event — water leaving a hydrate, a gas splitting off a carbonate, a polymer's backbone breaking apart. This simulator drives three reference materials through a controlled heating ramp using genuine multi-step Arrhenius kinetics: pick calcium oxalate monohydrate to watch three distinct mass-loss steps unfold in sequence, switch to pure calcium carbonate for a single sharp decarbonation, or load PVC and toggle the furnace atmosphere between inert nitrogen and oxidizing air to see its carbon char survive or burn away. A 3D crucible empties instance by instance as each step's extent of reaction advances, while a live strip chart plots the TGA mass curve alongside its derivative, DTG, whose peaks mark each event's temperature of fastest decomposition.
