Method 3: Gas Analysis for CO2, O2, Excess Air and Dry Molecular Weight

This method provides for gas captured froma source to be delivered to a Tedlar bag at a constant flow rate. The bag contents is then analyzed for the gaseous parameters of interest. If a leak-free pump is placed in-line before the Tedlar bag, a moisture removal system must precede the pump for protection.

Intrinsically Safe Bag Sampling System

ESC Integrated Bag Sampling Systems include a bag vessel (10, 20, 30, 50 or 100 Liter internal volumes), a pump module with rotameter, valve, vacuum gauge and a quick connect on the vacuum and pressure side of the pump. The bag vessel is intrinsically safe, capable of maintaining 29" Hg vacuum, and can be used to sample in volatile areas where the use of electricity is prohibited.

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.

GCU-2 Coil Condenser System

Coil Condenser systems include either a coil condenser in an ice bath, such as our GCU series of moisture knockout systems, or a series of knockout impingers that comprise the condensing system as used in Method 4. Coil condensers are available with FEP Teflon or stainless steel coils and include a PFA Teflon catch vessel and a peristaltic pump to evacuate the collected condensate. 

Method 4: Determination of moisture content in stack gases

The Method 4 sampling train is an abbreviated Method 5 system that provides all of the equipment necessary to determine moisture content with the addition of our M5-CB-PA Probe Support Panel and M5-JB-1 Power Distribution Box that mount directly to the standard cold box that holds the condenser set of impingers.
