Overview

ISO 22744-1:2020 specifies a standardized test method for the qualification and quantification of organotin compounds in textiles and textile products. Part 1 defines a derivatisation method using gas chromatography (GC) with mass selective detection (GC‑MS). The method extracts organotins from textile materials, converts polar/high‑boiling organotin species into volatile alkyl derivatives using sodium tetraethylborate, and determines them by GC‑MS. The standard is applicable to all types of materials of textile products (see CEN/TR 16741 for material applicability).

Key topics and technical requirements

Extraction and complexing: Organotin substances are extracted with a methanol–ethanol mixture using tropolone as a complexing agent.

Derivatisation reagent: Conversion to alkyl derivatives is achieved by sodium tetraethylborate (NaB(Et)4); solutions must be prepared in a fume hood and stored under inert gas (stable ≈ 3 months).

Instrumentation: Analysis requires a gas chromatograph with a mass selective detector (GC‑MS); Annex A suggests GC‑MS conditions.

Target compounds and internal standards: The standard lists mono‑, di‑, tri‑ and tetra‑substituted organotins and recommended internal standards. Tables and weighting factors are provided to convert organotin chlorides to organotin cation concentrations.

Sample preparation: Test pieces should be particles with a maximum edge length of 4 mm; up to three specimens may be combined if appropriate.

Calibration and quantification: Procedures for preparing stock and working standard solutions, calibration solutions, and calculation of mass concentration (ρ = ρCl × W) are included.

Safety: Explicit safety warnings-sodium tetraethylborate is air‑sensitive and can spontaneously combust; organotins are toxic and endocrine disruptors.

Quality and reporting: Requirements for blanks, expression of results, method reliability (Annex B) and test reporting are specified.

Applications and users

Who would use ISO 22744-1:2020:

Textile laboratories performing regulatory compliance testing for organotin compounds.

Manufacturers and chemical compliance teams verifying raw materials, coatings and finished textiles.

Regulatory bodies and accredited testing organizations assessing consumer safety and environmental risk.

R&D and quality control groups developing safer alternatives to organotin-based additives.

Practical uses:

Screening and quantifying organotin residues in fabrics, coatings and polymer components.

Supporting product compliance with chemical safety regulations and restricted substance lists.

Providing reproducible GC‑MS methods for inter‑laboratory comparison and certification.
