Surface active agents — Determination of 1,4-dioxan residues in surfactants obtained from epoxyethane by gas chromatography
ISO 17280:2015 provides a method for the determination of 1,4-dioxane residues in surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates. The method is applicable for samples containing 1,4-dioxane more than 5 mg/kg. For samples containing 1,4-dioxane more than 100 mg/kg, the sample solutions should be diluted to appropriate concentration.

Površinsko aktivne snovi - Določevanje ostankov 1,4-dioksana v površinsko aktivnih snoveh, pridobljenih iz epoksietana, s plinsko kromatografijo
Ta mednarodni standard podaja metodo za določevanje ostankov 1,4-dioksana v površinsko aktivnih snoveh, sintetiziranih iz epoksietana, kot so alkil eter sulfati in alkoholni etoksilati.
Metoda se uporablja za vzorce z vsebnostjo 1,4-dioksana več kot 5 mg/kg. Za vzorce z vsebnostjo 1,4-dioksana več kot 100 mg/kg je treba vzorčne raztopine razredčiti do ustrezne koncentracije.

1 Scope
This International Standard provides a method for the determination of 1,4-dioxane residues in
surfactants which are synthesized from epoxyethane, such as alkyl ether sulfates and alcohol ethoxylates.
The method is applicable for samples containing 1,4-dioxane more than 5 mg/kg. For samples containing
1,4-dioxane more than 100 mg/kg, the sample solutions should be diluted to appropriate concentration.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

ISO 3696, Water for analytical laboratory use — Specification and test methods
ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results — Part 2: Basic method
for the determination of repeatability and reproducibility of a standard measurement method
3 Principle
The sample is weighed into a head space vial and a calibration solution is added. The sealed vial is
placed in a head space sampling instrument and allowed to reach thermal equilibrium. A portion of the
vapour phase is then analysed by temperature programmed GC with flame ionization detection. Either
an internal standard or standard addition method of quantification are employed.
4 Reagents
During the analysis, use only reagents of recognized analytical grade and the water used shall conform
to grade 3 in accordance with ISO 3696.
