5 Sampling of N‐nitrosamines from test chamber air
N-nitrosamines in air samples are collected on special cartridges and are analysed either by GC-TEA or
HPLC-MS/MS.
Air samples shall be collected in duplicate. For this, N-nitrosamines from test chamber air shall be
collected simultaneously (or immediately sequentially) on two samplers.
A measured volume of 100 l of air from the emission test chamber is drawn at a controlled flow rate
(from 1,5 l/min to 2,0 l/min) through the sampler at specified times (as specified in
EN 16516:2017+A1:2020) during the emission test. The vapour-phase N-nitrosamines present in the
chamber air are trapped on the samplers as the air passes through. The sampler shall prevent the
formation of N-nitrosamines from amines, usually by use of an inhibitor (Example: Thermosorb-N Air
Sampling Cartridges from Ellutia). The loaded samplers may be stored or transported for a maximum of
seven days at room temperature before elution for analysis.
To confirm the absence of the N-nitrosamines, an additional sampling is recommended 24 h after the
start of the emission test due to the high volatility of the N-nitrosamines.
NOTE Materials containing vulcanising agents have a potential to form N-nitrosamines.
6 Preparation for subsequent analysis
6.1 General
The samplers are extracted in opposite direction of air sampling.
6.2 Elution for subsequent analysis with GC‐TEA
The loaded samplers are placed in an upright position with the “air-in” side on top. 100 µl internal
standard solution (see 7.1.2) are added with a syringe and left for 5 min. The sampler is turned around
that the “air-out” side of sampling is up and a 2 ml-vial is placed under the “air-in” side of the tube. The
sampler is eluted with 2 ml dichloromethane/methanol 3:1 mixture. The eluates are then analysed by
GC-TEA as described in 7.1.2.
NOTE Approximately 1 ml of extract is received, internal standard method compensates for varying extract
volume.
6.3 Elution for subsequent analysis with HPLC‐MS/MS
The loaded samplers are eluted with 1,5 ml methanol and made up to 2 ml. After shaking, the eluates
are left to settle for 5 min and then filtrated through a 0,2 µm membrane filter. The eluates are then
analysed by HPLC-MS/MS as described in 7.1.3.
NOTE Crystallization is sometimes observed after elution, therefore it is advisable to leave the eluates for
10 min before filtration.
6.4 Storage of eluted samples
The eluates can be stored for at least 14 days in a refrigerator protected from light at a temperature
below 4 °C without analyte losses. Tight-sealing vials are required to prevent the loss of the solvent.
7 Analysis and quantification
7.1 Analytical method of determination
7.1.1 General
The analytical step shall be carried out twofold for each eluate.
7.1.2 Calibration and analysis with GC‐TEA
A calibration shall be carried out before analysis of samples.
Commercially available standard solutions (single or mixture) may be used for calibration. N-Nitroso-
propylbutylamine (NPBA) is used as internal standard.
Examples of stock solutions:
— Analyte stock solution (1 µg/ml of each analyte): 100 µl of the commercially available standard
solution (100 µg/ml in methanol) is filled-up in a 10 ml brown glass flask to the mark with a
mixture of dichloromethane/methanol 3:1.
— NPBA stock solution (1 µg/ml): 1 ml of the commerci
