Laboratory Testing Services:

Our Laboratory follows EPA OTM-40 for the analysis of hydrogen chloride sorbent traps. Sorbent Traps are analyzed via ion chromatography. They are typically used to measure HCl content in coal-fired flue gas before a Method 26 or Method 26A compliance test. OTM-40 can also be used in lieu of Method 26 for compliance purposes, following the guidelines described in Alternative Test Method 129.

Hydrogen Chloride Analysis

NH3 sorbent traps are used to measure ammonia slip after SCRs, as well as ammonia concentrations between SCR layers. These sorbent traps are analyzed via ion chromatography.

Ammonia Analysis

SO3 Sorbent Traps are typically used in lieu of Method 8/8A/CTM-013 for engineering studies and process analysis, especially where Method 8 is too difficult to perform at the sampling site. Common applications include measurement of H2SO4 emissions from coal-fired power plant stacks, as well as testing of SO2 → SO3 conversion across an SCR module or other catalyst. These traps can be analyzed via ion chromatography or barium-thorin titration as requested.

Sulfur Trioxide/Sulfuric Acid Analysis

Our arsenic sorbent traps are also used for the capture and analysis of selenium, using the same analytical methods. Selenium measurements are typically of interest to utilities affected by EPA’s Effluent Limitations Guidelines (ELG), since the traps can be used to evaluate selenium control technologies in the gas phase, prior to selenium capture in the FGD.

Selenium Analysis

Our laboratory analyzes Method 26 and 26A samples for HCl, HBr, Cl2, and Br2.

Sampling Equipment and Supplies:

The sorbent traps used for capture and analysis of HCl can also be used for measurement of hydrogen bromide (HBr). These measurements are typically performed for engineering tests around Air Pollution Control Devices (APCDs). This measurement has been useful for testing native and artificial hydrogen bromide concentrations for the purpose of mercury oxidation.

Hydrogen Bromide Analysis
Arsenic Analysis

These sorbent traps are analyzed via hydride generation atomic fluorescence spectrometry (HGAFS) or graphite furnace atomic absorption spectrometry (GFAAS). Their common application is the evaluation of limestone combustion or injection and its effects in arsenic mitigation for the purpose of preventing catalyst poisoning.
