About This Simulation

This interactive visualization demonstrates the core components of an Inductively Coupled Plasma (ICP) torch, the heart of ICP-MS and ICP-OES instrumentation. The simulation shows:

RF Generator

A radiofrequency generator (27.12 or 40.68 MHz) powers the load coil, creating an oscillating magnetic field that sustains the plasma through inductive heating.

Argon Flow

Three concentric argon flows—auxiliary (coolant), plasma, and nebulizer (carrier)—work together to form and shape the plasma while transporting the sample aerosol.

Plasma Torch

At ~10,000 K, the argon plasma atomizes and ionizes sample atoms. This temperature is hot enough to ionize most elements in the periodic table with high efficiency.

🎮 How to Use

  • RF Generator — Click to toggle the radiofrequency power. The coil will glow orange when active.
  • Ar Flow — Click to toggle argon gas flow. Watch the particles stream through the torch tubes.
  • Both must be ON to ignite the plasma. Try turning one off to see what happens!
  • Sound — Click the speaker icon to hear the electrical hum and gas flow (unmute to enable).
