Polycyclic aromatic hydrocarbons (PAH) may be formed in technical processes, in which organic, especially fossil substances are processed, burned or pyrolized. Guideline VDI 3874 specifies a manual method for the determination of PAH in emissions from stationary sources of all industrial ...
Stationary source emissions - Determination of the total of nitro-gen monoxide and nitrogen dioxide - Ion chromatographic method
The emission of nitrogen oxides (NOx) from combustion processes and other industrial processes contributes significantly to air pollution. The guidline VDI 2456 specifies a wet chemical method which is applicable to the determination of the mass concentration of nitrogen monoxide and nitrogen ...
The guideline VDI 3451 deals with the formation, prevention, abatement and measurement of hydrogen chloride containing emissions, which arise from production and processing of gaseous and aqueous hydrochloric acid, furthermore processes are dealt with in which hydrogen chloride is a by-product. ...
Guideline 3892 Part 5 describes a method for the determination of lower aldehydes especially acrolein (2-propenal) in waste gases of e.g. firing plants (especially wood firing), of internal-combustion engines or smokehouses as well as of foundries or chemical productions. The present Guideline ...
Guideline VDI 3499 Part 2 and 3
The Guideline VDI 3499 describes emission measurement methods for the sum of the 17 polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF) according to the international toxicity equivalents (I-TEQ). The methods described in Part 2 and 3 which differ especially regarding sampling, are ...
Guideline VDI 3481 Part 4 (Draft)
The FID method, which is specified in guideline VDI 3481 Part 4, allows both the measurement of total organic carbon (TOC) and the measurement of methane. The combined measurement is made possible by using a selective catalytic converter, which nearly completely removes the organic compounds ...
Guideline VDI 3862: Gaseous emission measurement
Guideline VDI 3862 describes measurement procedures for the determination of aldehydes and ketones in stack emissions. The present parts broaden the spectrum of proven measurement procedures with two more methods. Guideline 3892 Part 6 describes a method which is used for ambient and indoor air ...
The parts of this guideline describe complete methods to determine the metals and metalloids in the suspended particulate matter of the ambient air and in the dust deposition, which enter ambient air from combustion plants and during their manufacture and processing. The selection of components ...
