What is ISO 20264 - Mass concentration of individual VOCs on emissions about?
ISO 20264 discusses stationary source emissions with a focus on the determination of the mass concentration of individual volatile organic compounds (VOCs) in waste gases. ISO 20264 specifies the use of FTIR spectrometry for determining the concentrations of individual
volatile organic compounds (VOCs) in waste gases from non-combustion processes. It provides a method that is employed to continuously analyze sample gas that is extracted from ducts and other sources.
ISO 20264 describes the principle, sampling procedure, IR spectral measurement and analysis, calibration, handling interference, QA/QC procedures, and some essential performance criteria for measurement of individual VOCs.
Note: A bag sampling method can also be applied, if the compounds do not adsorb on the bag material and are appropriate in cases where it is difficult or impossible to obtain a direct extractive sample.
Who is ISO 20264 - Mass concentration of individual VOCs on emissions for?
ISO 20264 on mass concentration of individual volatile organic compounds applies to entities such as power plants, petroleum refineries, petrochemical plants, food processing plants, and other heavy industrial sources. ISO 20264 is useful for:
- Environmental regulatory bodies
- Industrial installations emitting gases
- Safety and regulatory authorities
- Laboratories
Why should you use ISO 20264 - Mass concentration of individual VOCs on emissions?
ISO 20264 provides a measurement in the infrared (IR) region over a wide spectral band. Analysis of the recorded spectra enables the concentration of a wide number of compounds to be quantified simultaneously. Overlap of IR absorption features with each VOC can affect the quantification of each compound. However, by using appropriate chemometric procedures for the overlapping IR spectra of VOCs, the concentrations are quantified for the individual compounds of interest.
ISO 20264 specifies the measurement method for determining concentrations of individual VOCs in waste gases from non-combustion processes by using FTIR spectroscopy. There are various volatile organic compounds (VOCs) emitted from stationary sources where organic solvents are used for painting, printing, cleaning, degreasing, and chemicals production.
