DILUTER, ANALYSIS SYSTEM, AND ANALYSIS METHOD

DILUTER, ANALYSIS SYSTEM, AND ANALYSIS METHOD

To uniformly dilute particulate matter contained in a sample gas, a diluter (3, 3', 3") includes an inflow portion (31), a mixing portion (32, 32"), a discharge portion (35), a connection portion (33), and an introduction portion (34). The inflow portion (31) allows a sample gas (SG)...

description To uniformly dilute particulate matter contained in a sample gas, a diluter (3, 3', 3") includes an inflow portion (31), a mixing portion (32, 32"), a discharge portion (35), a connection portion (33), and an introduction portion (34). The inflow portion (31) allows a sample gas (SG) to flow in. The mixing portion (32, 32") has an inner diameter larger than that of the inflow portion (31), and mixes the sample gas (SG) with a dilution gas (AR) to generate a diluted sample gas (DG). The discharge portion (35) discharges the diluted sample gas (DG). The connection portion (33) has a first tapered part (33a) whose inner diameter increases from a side connected to the inflow portion (31) toward a side connected to the mixing portion (32, 32"). The introduction portion (34) introduces the dilution gas (AR) into an internal space (IS1) from a position downstream of the connection between the first tapered part (33a) and the inflow portion (31).
