DILUTION SYSTEM OF A REFERENCE GAS, CAPABLE OF AUTOMATICALLY DILUTING A REFERENCE GAS OF HIGH CONCENTRATION TO MAKE THE GAS OF DESIRED CONCENTRATION

摘要

PURPOSE: A dilution system of a reference gas is provided to immediately stabilize a high concentration specimen with nitrogen after injecting the specimen so that a rapid dilution is possible.;CONSTITUTION: A dilution system(10) of a reference gas comprises a first multi-path valve(100), a second multi-path valve(200), and a controller. A reference gas and a dilution gas flow into the first multi-path valve. The first multi-path valve discharges the reference gas and the dilution gas. The second multi-path valve comprises one or more loops having various volumes. The second multi-path valve is connected to the first multi-path valve through a gas inflow path and a gas discharging path. The controller controls the rotations of the first and second multi-path valves.;COPYRIGHT KIPO 2012
