Method 17 provides in-stack filtration of particulate and eliminates the requirement of the Method 5 heated filter box. Our PRI-TO Stainless Steel Thimble Filter Holder, used for high particulate loading, holds both 30mm x 100mm glass fiber thimbles and 34mm x 100mm Alundum thimbles. The PRI-T-P Pyrex Thimble Filter Holder holds 30mm x 100mm Glass or Quartz fiber thimbles and is predominantly used in applications where it is prohibited to have metal in the sample pathway. Our GFS-2-10 Stainless Steel 47mm Filter Holder holds flat 47mm diameter glass fiber filter paper and is for low particulate loading applications. Both filter holders have 5/8" union fittings on inlet and outlet ends for fastening directly between the nozzle and probe sheath. Both stainless steel filter holders are available in Teflon coated stainless steel, specifically designed for mercury testing.

A Method 17 sampling train can be set up with an isolated probe and flexible heated or unheated sample transfer line to the impingers, or with the probe directly linked to the impinger set using our probe support adapter panel mounted to the impinger box.
