Method 10: Determination of carbon monoxide emissions from stationary sources

BSS-PC Integrated Bag Samper

Our BSS-100-PC Integrated Bag Sampling System is used to collect 60 to 90 liters of integrated sample in a Tedlar bag for analysis by NDIR. This lung system inflates the Tedlar bag with sample at a constant rate through an isolated sample pathway by evacuating the leak-free vessel that surrounds the Tedlar bag, using the PS-33 Pump Assembly.

PS-33 Pump Assembly

The PS-33 Pump Assembly includes a rotameter, valve, vacuum gauge and a quick connect on each of the vacuum and pressure sides of the pump.

GCU Series Sample Conditioner

Our GCU-1 conditioning system delivers a dry continuous sample directly to the analyzer. Sample exiting the probe passes through a Teflon coil condenser submerged in an ice bath. The excess moisture is captured in a Teflon collection vessel and removed by a peristaltic pump.

Method 17: Determination of particulate emissions from stationary sources (in-stack filtration method)

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.

PRI-T-HOOK Shepherd’s Hook

For vertical sampling, our PRI-T-HOOK is the ideal accessory to orient the thimble filter in an upright position, thus permitting gravity to assist the sample vacuum in keeping the particulate catch in the filter. 

The M17-SR Strain Relief is a probe mounted adapter used to hold the weight of a sample transfer lines to relieve stress at the probe liner connection.

Method 18: Measurement of gaseous organic compound emissions by gas chromatography

BSS-10 Intrinsically Safe Bag Sampling System

This method requires a Teflon or stainless steel pathway for integrated sampling into a Tedlar bag. Our Bag Sampling Systems, featuring our transparent bag vessels in 10, 15, 20 and 30 liter sizes, are used to collect an integrated sample in a Tedlar bag. The intrinsically safe vessel can be evacuated to 30"Hg vacuum prior to sampling and used in volatile areas where electrical equipment is prohibited. The system inflates the Tedlar bag with sample at a constant rate through the inert sample pathway by applying vacuum to the leak-free vessel that surrounds the Tedlar bag. The ideal bag connection for Method 18 is a double end shutoff quick connect stem, male adapter and Teflon nut that connects directly to a female stainless steel quick connect and 3-way valve assembly in the center of the vessel cover. The 3-way valve allows the probe to be purged before inflating the bag with sample. An additional female quick connect in the cover connects to a vacuum line that runs to either the pressure port of the pump for evacuating the Tedlar bag before sampling, or the vacuum port of the pump for evacuating the vessel during sampling. The integrated sample is analyzed for total gaseous organics by gas chromatography.

Tedlar Bags

ESC makes Tedlar bags in a variety of sizes and with a variety of valve configurations. Valves include a nickle plated hose barb valve, a septum fitting, a polypropylene valve and septum fitting, and a Teflon nut used to receive a variety of stainless steel quick connects or unions.
