This document describes a method for the sampling and measurement of mercury of both vapour and solid phases on stationary source flue gas streams. Mercury generally exists as elemental (Hg0) and oxidized (Hg2+) forms, both in the vapour and solid phases in flue gases. The vapour-phase (gaseous) mercury is captured either isokinetically or non-isokinetically with a gold amalgamation trap after removing solid-phase (particulate) mercury with a filter. Because gold amalgamation trap captures only gaseous elemental mercury, the oxidized mercury (Hg2+) in the vapour phase is converted to elemental mercury (Hg0) prior to the gold amalgamation trap. The concentration of gaseous mercury is determined using atomic absorption spectrometry (AAS) or atomic fluorescence spectrometry (AFS) after releasing mercury by heating the gold amalgamation trap. Separately, particulate mercury is collected isokinetically on a filter and the concentration is determined using cold vapour AAS or cold vapour AFS after dissolving the particulate mercury into solution.
The total concentration of mercury in flue gas is expressed as the sum of both gaseous and particulate mercury concentrations.
The gold amalgamation method is intended for short-term (periodic) measurements of gaseous mercury ranging from 0,01 μg/m3 to 100 μg/m3 with sampling volumes from 0,005 m3 to 0,1 m3 and sample gas flow rate between 0,2 l/min to 1 l/min. The measurement range of particulate mercury is typically from 0,01 μg/m3 to 100 μg/m3 with sampling volume from 0,05 m3 to 1 m3.

This document specifies the use of FTIR spectrometry for determining the concentrations of individual volatile organic compounds (VOCs) in waste gases from non-combustion processes. The method can be employed to continuously analyse sample gas which is extracted from ducts and other sources. A bag sampling method can also be applied, if the compounds do not adsorb on the bag material, and is appropriate in cases where it is difficult or impossible to obtain a direct extractive sample.
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 are described in this document.
NOTE 1 The practical minimum detectable concentration of this method depends on the FTIR instrument (i.e. gas cell path length, resolution, instrumental noise and analytical algorithm) used, compounds, and interference specific (e.g. water and CO2).

This document specifies a manual method of measurement including sampling and different analytical methods for the determination of the mass concentration of ammonia (NH3) in the waste gas of industrial plants, for example combustion plants or agricultural plants. All compounds which are volatile at the sampling temperature and produce ammonium ions upon dissociation during sampling in the absorption solution are measured by this method, which gives therefore the volatile ammonia content of the waste gas.
This document specifies an independent method of measurement, which has been validated in field tests up to a NH3 concentration of approximately 65 mg/m3 at standard conditions.
This method of measurement can be used for intermittent monitoring of ammonia emissions as well as for the calibration and validation of permanently installed automated ammonia measuring systems.

The purpose of this Technical Specification is to establish performance benchmarks for, and to evaluate the acceptability of, sorbent trap monitoring systems used to monitor total vapour-phase mercury (Hg) emissions in stationary source flue gas streams. These monitoring systems involve continuous repetitive in-flue sampling using paired sorbent traps with subsequent analysis of the time-integrated samples.
This Technical Specification is suitable for both short-term (periodic) measurements and long-term (continuous) monitoring using sorbent traps.
the substance measured according to this Specification is the total vapour phase mercury in the flue gas, which represents the sum of the elemental mercury and gaseous forms of oxidised mercury such as mercury (II) chloride, the mass concentration units of micrograms per dry meter cubed. The analysis range is typically 0,1 to greater than 50 µg/m3.
The sorbent tube approach is intended for use under relatively low particulate conditions (typically less than 100 mg/m3) when monitoring downstream of all pollution control devices, e.g., at coal fired power plants and cement plants. In this case, the contribution of mercury in the particulate fraction is considered to be negligible (typically less than 5 % of total mercury). However, it shall be noted that the sorbent trap does take account of the finest particle fraction that is sampled with the flue gas, in addition to capturing the vapour phase mercury.
This Specification also contains routine procedures and specifications that are designed to evaluate the ongoing performance of an installed sorbent trap monitoring system. The operator of the industrial installation is responsible for the correct calibration, maintenance and operation of this long-term sampling system. Additional requirements for calibration and quality assurance of the long-term sampling system are then defined in EN 14884 and EN 14181.

This International Standard describes the method for the sampling and determination of selenium
compounds in both vapour phase and solid phase that are entrained in flue gases carried in stacks or
ducts. The selenium content in flue gas is expressed as a mass concentration of elemental selenium in
the stack gas.
Particulate and gaseous selenium compounds are captured by a filter and an absorber solution,
respectively. The total concentration of selenium compounds in flue gas is expressed as the sum of both
concentrations.
The concentrations of selenium in both samples are determined using inductively coupled plasma
optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS)
or graphite furnace atomic absorption spectrometry (GFAAS). Hydride generation (HG) techniques
coupled to atomic spectrometry can also be used such as HG-AAS, HG-AFS (atomic fluorescence
spectrometry), HG-ICP-OES and HG-ICP-MS.
The detection limit for gaseous selenium compounds is 0,3 μg/m3 using HG-ICP-MS at a sampling
volume of 0,12 m3. The detection limit for particulate selenium compounds is 0,001 2 μg/m3 using this
technique at a sampling volume of 2,0 m3.

This International Standard specifies the fundamental structure and the most important performance
characteristics of automated measuring systems for ammonia (NH3) to be used on stationary source
emissions, for example, combustion plants where SNCR/SCR NOx control systems (deNOx systems) are
applied. The procedures to determine the performance characteristics are also specified. Furthermore,
it describes methods and equipment to determine NH3 in flue gases including the sampling system and
sample gas conditioning system.
This International Standard describes extractive systems, based on direct and indirect measurement
methods, and in situ systems, based on direct measurement methods, in connection with a range of
analysers that operate using, for example, the following principles:
— ammonia conversion to, or reaction with NO, followed by chemiluminescence (CL) NOx difference
measurement for ammonia (differential NOx);
— ammonia conversion to, or reaction with NO, followed by non-dispersive ultraviolet (NDUV)
spectroscopy NOx difference measurement for ammonia (differential NOx);
— Fourier transform infrared (FTIR) spectroscopy;
— non-dispersive infrared (NDIR) spectroscopy with gas filter correlation (GFC);
— tuneable laser spectroscopy (TLS).
The method allows continuous monitoring with permanently installed measuring systems of NH3
emissions, and is applicable to measurements of NH3 in dry or wet flue gases, for process monitoring,
long term monitoring of the performance of deNOx systems and/or emission monitoring.
Other equivalent instrumental methods can be used, provided they meet the minimum requirements
proposed in this International Standard. The measuring system can be calibrated with certified gases,
in accordance with this International Standard, or comparable methods.
The differential NOx technique using CL has been successfully tested on some power plants where the
NOx concentration and NH3 concentration in flue gas after deNOx systems are up to 50 mg (NO)/m3 and
10 mg (NH3)/m3, respectively. AMS based on FTIR, NDIR with GFC and TLS has been used successfully
in this application for measuring ranges as low as 10 mg (NH3)/m3.

The purpose of this document is to establish performance benchmarks for, and to evaluate the acceptability of, sorbent trap monitoring systems used to monitor total vapour- phase mercury (Hg) emissions in stationary source flue gas streams. These monitoring systems involve continuous repetitive in-flue sampling using paired sorbent traps with subsequent analysis of the time-integrated samples.
This document is suitable for both short-term (periodic) measurements and long-term (continuous) monitoring using sorbent traps.
NOTE   When this Technical Specification has been validated, the sorbent trap method will be an Alternative Method subject to the restrictions on applicability defined below. Until that time, EN 13211 is the only accepted Reference Method for both short-term (periodic) measurements and for calibrating continuous monitoring systems, including those with long-term sampling systems. EN 13211 is a wet chemistry approach that relies on absorption of mercury into impinger solutions.
The substance measured according to this specification is the total vapour phase mercury in the flue gas, which represents the sum of the elemental mercury (Hg0) and gaseous forms of oxidized mercury (Hg2+), such as mercury (II) chloride, in mass concentration units of micrograms (μg) per dry meter cubed (m3). The analytical range is typically 0,1 to greater than 50 µg/m3.
The sorbent tube approach is intended for use under relatively low particulate conditions (typically less than 100 mg/m3) when monitoring downstream of all pollution control devices, e.g. at coal fired power plants and cement plants. In this case, the contribution of mercury in the particulate fraction is considered to be negligible (typically less than 5 % of total mercury). However, it shall be noted that the sorbent trap does take account of the finest particle fraction that is sampled with the flue gas, in addition to capturing the vapour phase mercury.
This specification also contains routine procedures and specifications that are designed to evaluate the ongoing performance of an installed sorbent trap monitoring system. The operator of the industrial installation is responsible for the correct calibration, maintenance and operation of this long-term sampling system. Additional requirements for calibration and quality assurance of the long-term sampling system are then defined in EN 14884 and EN 14181.

These standards (EN 13284-1 and -2) have been published for over 10 years without revision. Significant advances have happened in the measurement of particulate at low concentration using continuous methods. Also various research studies carried out in the UK have indicated that there are some aspects of measuring low concentration of dust by the manual method require strengthening. Sections to be added should include: 1. filter preparation, conditioning and handling, 2. the number of samples required for an average measurement, 3. limit of quantification (separate from limit of detection). The standards also need revising to line up with EN 15259 as there is significant overlap in EN 13284 Part 1. EN 13284-2 needs to be updated to reflect imminent amendments in EN 14181 (from which it is derived).

This document describes a reference method for the measurement of particulate matter (dust)
concentration in waste gases of concentrations from 20 mg/m3 to 1 000 mg/m3 under standard
conditions.
This document is applicable to the calibration of automated monitoring systems (AMS). If the emission
gas contains unstable, reactive or semi-volatile substances, the measurement will depend on the
filtration temperature. In-stack methods can be more applicable than out-stack methods for the
calibration of automated monitoring systems.

This European Standard specifies a reference method for the measurement of low dust concentration in ducted gaseous streams in the concentrations below 50 mg/m3 at standard conditions. This European Standard is primarily developed and validated for gaseous streams emitted by waste incinerators. More generally, it may be applied to gases emitted from stationary sources, and to higher concentrations. If the gases contain unstable, reactive or semi-volatile substances, the measurement depends on the sampling and filter treatment conditions. This method has been validated in field tests with special emphasis to dust concentrations around 5 mg/m3. The results of the field tests are presented in Annex A.

This European Standard specifies a procedure to demonstrate the equivalence of an alternative method (AM) with the reference method (RM) or the standard reference method (SRM), both implemented to determine the same measurand.
In particular, this European Standard provides the statistical tools and different criteria to evaluate the alternative method. This does not release the body performing the equivalence testing from bearing technical and analytical judgement on the evaluation of the different criteria.
Three steps are required for demonstration of equivalence:
   description of the alternative method and setting of the field of application (measurement range and type of gas matrix);
   determination of the performance characteristics of the alternative method and calculation of the expanded uncertainty where appropriate and check of compliance with the maximum expanded uncertainty allowed for the reference method;
   check of repeatability and lack of systematic deviation of the alternative method in the field or on a recognized test bench in comparison with the reference method for the type of matrix defined in the field of equivalence.
This European Standard requires that a reference method has been defined and validated.
This European Standard only considers the case of linear quantitative methods.
This European Standard has been drawn up for laboratories working in air quality measurements and consequently an example taken from this sector are presented in Annex A.
