Low temperature plasma detection is a widely used method in the performance detection of clinical medical equipment. The basic material of this method is the low temperature plasma chemical indicator card.
Working principle of low-temperature plasma: Under negative pressure in the cavity, heated (90℃) sterilizing agent (H2O2) is injected into the cavity. High-temperature H2O2 liquid will form gaseous state under negative pressure. At the same time, the electrode in the cavity and the cavity itself form a high voltage of tens of thousands of volts, which decomposes H2O2 into hydroxyl radical HO, releasing ultraviolet rays and a lot of energy.
