WebAPC operating principle. Argon plasma coagulation, APC for short, is an electrosurgical, monopolar procedure for superficial hemostasis, devitalization and ablation using ionized argon gas. Argon is an inert gas and can be easily ionized. WebGas plasma treatment of a biopolymer surface generates high energy reactive species that bond to the surface. Plasma treatment can be carried out in the presence of an inert or reactive gas, for example, air, argon, oxygen, or ammonia, with the formation of surface functional groups, such as –OH, –CHO, –COOH, or –NH2.
