Stationary source emissions - Determination of total volatile organic compounds (TVOCs) in waste gases from non-combustion processes - Non-dispersive infrared analyser equipped with catalytic converter (ISO 13199:2012)
This International Standard specifies the principle, the essential performance criteria and quality assurance/quality control (QA/QC) procedures of an automatic method for measuring total volatile organic compound (TVOC) content in waste gases of stationary sources, using a non-dispersive infrared absorption (NDIR) analyser equipped with a catalytic converter which oxidizes VOC to carbon dioxide. This method is suitable for the measurement of TVOC emissions from non-combustion processes. This method allows continuous monitoring with permanently installed measuring systems, as well as intermittent measurements of TVOC emissions. The method has been tested on field operation for painting and printing processes, where TVOC concentrations in the waste gases were from about 70 mg/m3 to 600 mg/m3.

Introduction
Volatile organic compounds (VOCs) play significant roles in atmospheric chemistry, especially the formation
of photochemical oxidants and/or ozone (O ) and suspended particulate matter (SPM), which are known to
3
have negative impacts on human health and biological systems. There are many areas of the world where their
atmospheric concentrations are close to or above the level of the WHO guidelines for environmental standards
in each nation. It is therefore strongly required in many nations to reduce the emission of VOC from various
anthropogenic sources.
In order to manage VOC emission from stationary emission sources, it is essential for enterprises to evaluate
the quantity of VOCs emitted from their facilities where organic solvents as well as other chemicals are used
for industrial processes like painting, printing, cleaning, and degreasing.
A technique for continuously and precisely measuring the concentration of total VOCs (TVOCs) in waste
gases emitted from ducts to atmosphere, which is easy to operate and to maintain, is very helpful for both
governments and enterprises to control and reduce VOC emissions. This measurement method, based on
the use of an NDIR analyser equipped with a catalytic converter for oxidation of TVOCs to CO , has some
2
advantages compared to measurement methods using flame ionization detection (FID) and FID–GC (flame
ionization detection–gas chromatography), namely:
a) high-safety operation is possible, since no flame and no hydrogen are used;
b) response factors of individual VOCs are not different from each other;
c) no interference due to oxygen is observed.
Note, however, that this method is not applicable to waste gas from combustion processes.

5 Principle
5.1 Method of measurement
The measuring system consists of a sample conditioning system and the NDIR analyser for measuring CO
2
equipped with the converter for oxidation of TVOCs to CO as shown in Figure 1. A portion of sample gas (gas
2
A) passes through the converter (and the moisture removal system), and goes into the NDIR analyser, while
another portion of sample gas (gas B) passes through (the moisture removal system), and goes into the NDIR
analyser. The difference in the CO concentration between gas A and gas B is equal to the concentration of
2
CO which comes from TVOCs.

5.2 Analyser equipment
The gas analysers use, as the measurement principle, the absorption of infrared radiation (IR) by the component
measured in characteristic wavelength ranges. The analysers operate according to the non-dispersive IR
(NDIR) method, while the selectivity of measurement is achieved by the radiation detector which is filled with
the component to be measured. Schematic diagrams of a typical NDIR analyser for measuring TVOC mass
concentration are given in Figures A.1, A.2, and A.3.
5.3 Performance criteria fulfilment
5.3.1 General. The automatic measuring system (AMS) based on the NDIR method shall comply with
the performance criteria specified in Table 1. The associated performance characteristics are determined as
specified in 5.3.2 to 5.3.4.
5.3.2 General performance test. The manufacturer of the measuring system shall demonstrate in a general
performance test that the relevant performance criteria listed in Table 1 are fulfilled by the instrument type. The
procedure of this general performance test shall comply with the relevant standards.
5.3.3 Ongoing quality assurance (QA) and quality control (QC) in the laboratory. The user of AMS shall
demonstrate during regular laboratory tests conducted within the ongoing QC programme that the relevant
performance criteria listed in Table 1 are fulfilled for the specific AMS.
5.3.4 Quality assurance during operation in the field. The user of AMS shall check during field operation
that the relevant performance criteria listed in Table 1 are fulfilled.
6 Performance criteria and determination of the performance characteristics
6.1 Performance criteria
Table 1 gives an overview of the relevant performance characteristics and performance criteria of the analyser
