FLOW CELL FOR MULTIPLEX REFLECTION CELL TYPE GAS ANALYSIS SYSTEM, MULTIPLEX REFLECTION CELL TYPE GAS ANALYSIS SYSTEM, AND ADJUSTMENT METHOD OF MIRROR-TO-MIRROR DISTANCE OF FLOW CELL

摘要

PROBLEM TO BE SOLVED: To provide a flow cell for a multiple reflection cell type gas analysis system, capable of easily compensating an effect of variation in curvature radius of Miller with no increase in cost, a multiple reflection cell type gas analysis system, and an adjustment method of a mirror-to-mirror distance of the flow cell.;SOLUTION: The flow cell includes: a cylindrical cell body 5 having a sample gas inlet 15 and a sample gas outlet 16; a first mirror 2a located at a first termination section of the cell body 5, having a tunnel 4 through which incident light and emission light pass; a second mirror 6 located at a second termination section of the cell body 5, having a second mirror surface opposed a first mirror surface of the first mirror 2a; and spacer insertion units (11b, 12, 17b, 18) for inserting a spacer 13 between the second termination section and the second mirror 6 to adjust the distance between the first mirror 2a and the second mirror 6.;COPYRIGHT: (C)2009,JPO&INPIT
