Definition of Plasma

Plasma is known as the fourth state of matter, in addition to the other three states:
Solid, liquid, and gas.  It consists of a group of positively charged ions and free electrons,generated when gas is supplied with sufficient energy, such as by electrical discharge causing the gas to become ionized.  Although composed of charged particles, plasma maintains an overall electrically neutral state due to the balance between positive and negative charges.
In CASP sterilizers, plasma plays a core role in the hydrogen peroxide low temperature sterilization process.  By applying radio frequency energy, plasma is generated throughout the entire chamber, activating the sterilant and accelerating its decomposition.  As a result, hydrogen peroxide breaks down into harmless by-products such as water and oxygen, ensuring safe, effective, and environmentally friendly sterilization, even for heat- or moisture-sensitive medical instruments.
