EPA Method 26A: Hydrogen Halides and Halogens- Isokinetic Method

The Environmental Supply Method 26a sampling system is for the determination of Hydrogen Halides such as Chloride, Fluoride, Bromide and Hydrogen Halogens such as Chlorine and Bromine. Method 26a is an isokinetic method which requires a Method 5 sampling train with the use of six impingers (instead of four impingers), reagents and PTFE coated glass fiber filter media. This method is particularly suited for sampling sources controlled by wet scrubbers emitting acid particulate matter. Sample flow rate averaging about 20 liters per minute. Teflon filters recommended unless the stack gas temperature exceeds 210 °C (410 °F), in which case a quartz fiber filter may be used.

Sampler Components Includes the following:

C-5000 Console with Open Frame Pump. The C-5000 Series consists of: 10” Dual inclined manometer with 1” incline and brass shutoff valves, manometer solenoid valves for on-the-fly zeroing capability, solid state temperature controllers for probe and filter, 7-station thermocouple selector switch, LED temperature readout, amphenol 4-pin fused power delivery, power-pump-timer-null-orsat power switch controls, brass valves and 1/2" QC sample inlet, 3/8" QC pitot inlets, 1/4" QC Orsat Inlet and pump connections.
