(Model 8300 Optima Manufactured by PerkinElmer)

The ICP has become the most widely used source for emission spectroscopy. Its success stems from its high stability, low noise, low background and freedom from much interference. When plasma energy is given to an analysis sample from outside, the component elements (atoms) will be excited.

When the excited atoms return to low energy level, emission rays are released and the emission rays that correspond to the photon wavelength are measured.

The element type is determined based on the energy level of the photon rays, and the content of each element is determined based on the ray intensity. To generate plasma, first, argon gas is supplied to torch coil, and high frequency electric current is applied to the work coil at the tip of the torch tube.

Solution samples are introduced into the plasma in an atomized state through the narrow tube in the center of the torch tube.
