Indoor air - Part 39: Determination of amines - Analysis of amines by (ultra-) high-performance liquid chromatography coupled to high resolution or tandem mass spectrometry
This document, along with ISO 16000-38, specifies the measurement method for determining the mass concentration of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) or high-resolution mass spectrometry (HRMS). The analytical procedure is covered by this document. The sampling procedure and the manufacturing of the samplers are covered by ISO 16000-38. This document describes specifications for the chromatography and the mass spectroscopy for the amines. Measurement results are expressed in μg/m3. Although primarily intended for the measurement of amines listed in Tables A.1 and A.2, it can also be used for the measurement of other amines in indoor air. This document gives instructions and describes procedures for the inclusion of other amines. The range of application of this document concerning the concentrations of amines in indoor air depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range of application can be expected to be from approximately 0,002 μg/m3 (100 l sample) up to 2 000 μg/ m3 (5 l sample) for a common analytical equipment (e.g. Waters „TQD“) for the majority of the amines listed in Tables A.1 and A.2. The analysis of derivatives of ethanolamine is usually about 10 times more sensitive and the analysis of short-chained aliphatic amines is usually about 10 times less sensitive than
the analysis of an average amine. The performance data of the analytical method is given in Annex B, particularly in Tables B.1 and B.2. This document can be used also for the determination of amines in water if the detection limit is sufficient. This document does not cover the determination of isocyanates in indoor air (nor in water samples) as corresponding amines (covered by ISO 17734-1 and ISO 17734-2).

Ta dokument, skupaj s standardom ISO 16000-38, določa metodo merjenja masne koncentracije primarnih, sekundarnih in terciarnih alifatskih ter aromatskih aminov v notranjem zraku z uporabo akumuliranega vzorčenja in visokozmogljive tekočinske kromatografije (HPLC) skupaj s tandemsko masno spektrometrijo (MS-MS) ali masno spektrometrijo visoke ločljivosti (HRMS). Dokument zajema analitični postopek. Postopek vzorčenja in izdelava vzorčevalnikov sta zajeta v standardu ISO 16000-38. Ta dokument opisuje specifikacije za kromatografijo in masno spektroskopijo aminov. Rezultati meritev so izraženi v μg/m3. Čeprav je dokument namenjen predvsem za merjenje aminov, naštetih v dodatku A.1 in A.2, se lahko uporablja tudi za merjenje drugih aminov v notranjem zraku. Dokument vsebuje navodila in opisuje postopke za vključitev drugih aminov. Področje uporabe tega dokumenta v zvezi s koncentracijami aminov v notranjem zraku je odvisno od linearnega obsega kalibracijske krivulje in s tem od volumna vzorca plina (tukaj: od 5 l do 100 l), volumna eluata (od 1 ml do 5 ml), volumna vbrizgavanja (od 1 μl do 10 μl) in občutljivosti analitične opreme (npr. linearni razpon od 2 pg do 2 ng amina). Področje uporabe je mogoče pričakovati od približno 0,002 μg/m3 (vzorec 100 l) do 2000 μg/m3 (vzorec 5 l) za skupno analitsko opremo (npr. vode »TQD«) za večino aminov iz preglednic A.1 in A.2. Analiza derivatov etanolamina je običajno približno 10-krat občutljivejša, analiza kratko verižnih alifatskih aminov pa je običajno približno 10-krat manj občutljiva kot
analiza povprečnega amina. Podatki o učinkovitosti analitske metode so navedeni v dodatku B, zlasti v preglednicah B.1 in B.2. Ta dokument je mogoče uporabiti tudi za določanje aminov v vodi, če je meja zaznavanja zadostna. Ta dokument ne zajema določevanja izocianatov kot ustreznih aminov v notranjem zraku (niti v vzorcih vode) (zajeto v standardih ISO 17734-1 in ISO 17734-2).

Introduction
ISO 16000 (all parts) describe general requirements relating to the measurement of indoor air pollutants
and the important conditions to be observed before or during the sampling of individual pollutants or
groups of pollutants, as well as the measurements procedures themselves.
The definition of indoor environment is given by ISO 16000-1. Dwellings [living rooms, bedrooms, do-
it-yourself (DIY) rooms, sport rooms and cellars, kitchens and bathrooms], workrooms or workplaces
in buildings which are not subject to health and safety inspections with respect to air pollutants (e.g.
offices, salesrooms), public buildings (e.g. restaurants, theatres, cinemas and other meeting rooms) and
passenger cabins of motor vehicles and public transportation are among the most important types of
indoor environment.

1 Scope
This document, along with ISO 16000-38, specifies the measurement method for determining the mass
concentration of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using
accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem
mass spectrometry (MS-MS) or high-resolution mass spectrometry (HRMS). The analytical procedure
is covered by this document. The sampling procedure and the manufacturing of the samplers are
covered by ISO 16000-38.
This document describes specifications for the chromatography and the mass spectroscopy for the
3
amines. Measurement results are expressed in µg/m .
Although primarily intended for the measurement of amines listed in Tables A.1 and A.2, it can also be
used for the measurement of other amines in indoor air. This document gives instructions and describes
procedures for the inclusion of other amines.
The range of application of this document concerning the concentrations of amines in indoor air
depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l
up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 µl up to 10 µl) and

amines
-3
nitrogen containing compounds with a sufficient vapor pressure (>10 Pa) and a free electron pair at
the nitrogen atom which can be protonated
4 Amines in indoor air
4.1 Properties of amines
Amines are basic and polar substances.
There are primary, secondary, tertiary, and quaternary amines.
Quaternary amines are not included in this document, as they have no free electron pair and therefore
have very different properties. In this document the term “amines” refers only to primary, secondary,
and tertiary amines.
Not protonated amines are oxidation sensitive.
Reaction of amines with acids results in ammonium salts of the amines. The ammonium salts are not
oxidation sensitive.
4.2 Origin and occurrence of amines
Amines are produced by technical chemical processes and processing and in addition by biotic or
abiotic decomposition of nitrogen compounds. Besides sources of biological origin, indoor air sources of
amines could be, for instance, products containing polyurethane, especially foams, e.g. in vehicle seats,
mattresses, pillows, and upholstered furniture or as thermal insulation or sound absorbing material.
Several amines, in particular aromatic amines, are known as harmful compounds. Furthermore, most
amines have an unacceptable odour in combination with a low odour threshold.
Further sources are for example food, e.g. fish (aliphatic amines), and cigarette smoke (aromatic
amines).
5 Analytical procedure
5.1 Preparation of sample solutions
ISO 16000-38 describes the procedure to get the aqueous eluate of the ammonium salts of the sampled
amines. The sample solution (which contains already approximately 0,02 µmol/µl up to 0,1 µmol/µl
phosphoric acid) can be used for the injection into the HPLC system without further treatment.

— precursor ion: M+1;
— collision gas: argon;
— calibration: external and additionally with Pyridine-d5 as internal standard.
5.4 High resolution mass spectrometry
+
— ionisation: electrospray ionisation, positive mode (ESI ).
5.5 Sample sequence and external calibration
— external calibration: run calibration standards at least at the beginning and at the end of a sample
sequence;
— every 25 samples or less and at the beginning and end, run a calibration blank and a calibration
check solution of an independent source;
— every 50 samples (for example) and at the end of a run, analyse an interference check solution (ICS).
6 Testing of the suitability of the equipment and the instrumental analysis
6.1 General
In Table A.3, several amines are listed which can interfere with another amine in the instrumental
analysis. In order to check and confirm the suitability of the selected system and procedure following
issues have to be tested.
6.2 High-performance or ultra-performance liquid chromatography (HPLC or UHPLC)
The chromatographic separation of following compounds has to be tested and confirmed:
a) Diethylamine (11) and N,N-Dimethylethylamine (24);
b) Isobutylamine (2) and n-Butylamine (10);
c) 2-(Dimethylamino)ethanol (8) and 2-(Ethylamino)ethanol (25);

Usually 4-Ethylmorpholine (4) and 2-(Diethylamino)ethanol (3) as well as Morpholine (13) and
2-(Dimethylamino)ethanol (8) cannot be separated sufficiently on pentafluorphenyl terminated
stationary phases. These compounds have to be distinguished by high resolution or tandem mass
spectrometry.
The chromatographic separation of Diethylamine (11) and N,N-Dimethylethylamine (24) is not always

Introduction
ISO 16000 (all parts) describe general requirements relating to the measurement of indoor air pollutants
and the important conditions to be observed before or during the sampling of individual pollutants or
groups of pollutants, as well as the measurements procedures themselves.
The definition of indoor environment is given by ISO 16000-1. Dwellings [living rooms, bedrooms, do-
it-yourself (DIY) rooms, sport rooms and cellars, kitchens and bathrooms], workrooms or workplaces
in buildings which are not subject to health and safety inspections with respect to air pollutants (e.g.
offices, salesrooms), public buildings (e.g. restaurants, theatres, cinemas and other meeting rooms) and
passenger cabins of motor vehicles and public transportation are among the most important types of
indoor environment.

Indoor air —
Part 39:
Determination of amines — Analysis of amines by (ultra-)
high-performance liquid chromatography coupled to high
resolution or tandem mass spectrometry
1 Scope
This document, along with ISO 16000-38, specifies the measurement method for determining the mass
concentration of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using
accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem
mass spectrometry (MS-MS) or high-resolution mass spectrometry (HRMS). The analytical procedure
is covered by this document. The sampling procedure and the manufacturing of the samplers are
covered by ISO 16000-38.
This document describes specifications for the chromatography and the mass spectroscopy for the
3
amines. Measurement results are expressed in µg/m .
Although primarily intended for the measurement of amines listed in Tables A.1 and A.2, it can also be
used for the measurement of other amines in indoor air. This document gives instructions and describes
procedures for the inclusion of other amines.
The range of application of this document concerning the concentrations of amines in indoor air
depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l
up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 µl up to 10 µl) and
the sensitivity of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range
3
of application can be expected to be from approximately 0,002 µg/m (100 l sample) up to 2 000 µg/
3
m (5 l sample) for a common analytical equipment (e.g. Waters „TQD“) for the majority of the amines
listed in Tables A.1 and A.2. The analysis of derivatives of ethanolamine is usually about 10 times more
sensitive and the analysis of short-chained aliphatic amines is usually about 10 times less sensitive than
the analysis of an average amine.
The performance data of the analytical method is given in Annex B, particularly in Tables B.1 and B.2.
This document can be used also for the determination of amines in water if the detection limit is
sufficient.
This document does not cover the determination of isocyanates in indoor air (nor in water samples) as
corresponding amines (covered by ISO 17734-1 and ISO 17734-2).

nitrogen containing compounds with a sufficient vapor pressure (>10 Pa) and a free electron pair at
the nitrogen atom which can be protonated
4 Amines in indoor air
4.1 Properties of amines
Amines are basic and polar substances.
There are primary, secondary, tertiary, and quaternary amines.
Quaternary amines are not included in this document, as they have no free electron pair and therefore
have very different properties. In this document the term “amines” refers only to primary, secondary,
and tertiary amines.
Not protonated amines are oxidation sensitive.
Reaction of amines with acids results in ammonium salts of the amines. The ammonium salts are not
oxidation sensitive.
4.2 Origin and occurrence of amines
Amines are produced by technical chemical processes and processing and in addition by biotic or
abiotic decomposition of nitrogen compounds. Besides sources of biological origin, indoor air sources of
amines could be, for instance, products containing polyurethane, especially foams, e.g. in vehicle seats,
mattresses, pillows, and upholstered furniture or as thermal insulation or sound absorbing material.
Several amines, in particular aromatic amines, are known as harmful compounds. Furthermore, most
amines have an unacceptable odour in combination with a low odour threshold.
Further sources are for example food, e.g. fish (aliphatic amines), and cigarette smoke (aromatic
amines).
