With industrialization, large quantities of gaseous and particulate matter are released into the environment. As a result, many former industrial sites and the surrounding environment have been exposed to chemical pollutants. Increasing environmental awareness and legislation has led to the introduction of new technologies to monitor emissions and potential harmful effects on the environment.
Alfa Chemistry offers a one-stop solution for stack emissions testing to assess the concentration and composition of pollutants emitted from industrial stacks or exhaust ducts to ensure that emissions comply with relevant environmental regulations and standards. We offer sampling sequences optimized using specific solutions or solid adsorbents to collect relevant analytes.
Samples are collected using an impactor series that absorbs the solution and prefilters are used to determine particle loading. Samples are analyzed using ion selective electrodes (ISE), titration, or ion chromatography (IC). Testing items: HCN, HCI, HF, Chlorine, Fluorine.
Metal emissions are sampled using an impinger system. Collect the gas load in an acidified hydrogen peroxide or potassium permanganate (Hg) solution. Analyze the following metals using ICP-OES/MS and AFS (Hg): Aluminum, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, calcium, chromium, cobalt, copper, iron, lead, lithium, mercury, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, silicon, silver, sodium, strontium, sulfur, tellurium, thallium, tin, titanium, tungsten, uranium, vanadium, zinc, hexavalent chromium.
Inorganic analysis
Sulfur dioxide from stationary sources: SO3 (or H2SO4) emissions are captured by 80% IPA impingement or by condensation. SO2 is captured and converted to sulfate by reacting with an aqueous hydrogen peroxide solution in an impinger. SO2 and SO3 are measured as sulfate by IC or barium-sorin titration. Ammonia from stationary sources: Air samples are collected using a sulfuric acid solution impactor. After distillation, the sample is analyzed photometrically. Nitrogen oxides (NOx) from stationary sources: NOx is captured by an oxidizing impact reagent and converted to nitrate. Total NOx is determined by the IC determination of nitrate.
Standard methods for stack emissions testing
Our stack emissions testing services are operated and analyzed in accordance with strict industry standard methods. Extensively validated, Alfa Chemistry can provide a range of approved analytical procedures for stationary source emissions. These standard methods ensure accurate, comparable and reliable testing and are widely recognized and accepted.
