PURPOSE:To cut down operation costs, by allowing plasma generating gas to circulate by connecting, beginning with the open side of a plasma torch part, followed by cold-wrapping vessel, compressor, gas holder, and gas admission part of the plasma torch part in a proper order. CONSTITUTION:At an opening of a plasma torch part, a system is mounted for circulation of Argon gas. Throughout this system, cold-wrapping vessels 10, 18 compressor 19, gas holder 20, and gas admission part of the plasma torch part are connected in a proper order for allowing the plasma generating gas to circulate. Thus, the plasma generating gas which has hitherto been discharged and consumed at a rate of approximately, 18l/min, when refilled once, can stand the analysis works, without consumption, by the ICP analyzer and consequently, operation costs of the ICP analyzer can be economized. |
