06-02-2004: 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 describes the method for acrolein as an example. In principle, the method can be used for other aldehydes.
The aldehydes are sampled on a solid sorbent in a sampling tube, which is coated with 2?HMP. The determination is carried out by reaction of aldehydes with 2-(hydroxymethyl)-piperidine (2-HMP) which react quantitatively to the corresponding oxazolidines. The latter are determined with gas chromatography after extraction with toluene.
Guideline VDI 3862 describes measurement procedures for the determination of aldehydes and phenols in stack emissions. The present part broadens the spectrum of proven measurement procedures with one more method.
Determination of NOx-Emissions - VDI Guidline 2456
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 nitr ... more

New Guidline for Measuring Dioxines
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 ... more
